Portal is a PC/X360 game where you play a silent female protagonist in a large
test facility, owned by Aperture Science. Aperture Science is a corporation in
the HalfLife Universe, and prior to HalfLife 2, a major competitor for funding
(provided by the DoD of course) against Black Mesa. Not a spoiler, just a fact.

1. [FAQ]
--------
"Why write this tutorial?"
Why not? Well, this morning, nobody had written one. By the time I typed it all
out, there were three posted. If someone has a problem with the others, maybe
I’ll state it in a different fashion, and help some people out. Plus, I have
some neat information on ApertureScience.com! Plus, I have camera information!
"A game about a Portal-Gun? Didn’t they have portals in Prey?"
Yes, they did, but they also had portals in "Narbacular Drop", which was made
by DigiPen (Before Prey had ever come out, if I recall correctly). The entire
team that made Narbacular Drop was hired by Valve. Right out of school. That’s
what you get for thinking with portals!
"I heard this game was short. Is it worth it?"
Absolutely. You won’t want to go back to other styles of games. It’s addictive!
"Are there only nineteen levels? That doesn’t sound like a lot."
There are actually twenty "Test Courses". They start their arrays at Zero. Of
course, the early puzzles are very simple, and you don’t even start with a
portal gun!
"I don’t?"
Nope. You start with your wits, and the ability to pick up objects.
"Well then, how do those portals randomly appear? Where do they come from?"
Do you see those vertical bars on the wall on either side of the portal? You
know, the white ones with the blue strips down the center? Those are GLaDOS’s
"Portal Generators". The computer can place portals wherever she likes, as long
as they are between Portal Generators. Now that’s an efficient security system!
"Didn’t I see some weird website about Aperture Science a while back?"
Probably. And yes, it’s related to Portal. Just point your browser to;
www.ApertureScience.com
or
www.ApertureLaboratories.com
or
www.ApertureLabratories.com
"How many Achievements are there?"
In both the XBox360 and the PC version, there are achievements. I can’t speak
for the XBox users, since I own the PC version, but maybe they’ll help me out.
The achievements section lists them all.
(Thanks to Elmo[aka: Wgpfly] for agreeing to help me out here)
"How can you play an entire First Person SHOOTER without a weapon?"
Well, it wasn’t easy, but when it comes down to it, Portal is really a Puzzle
Game at heart. Even when there are things shooting at you, you could
theoretically get through the whole game without taking any damage.
"You take damage? Whoa. How much life do you have?"
As long as you don’t get hit by too many bullets, you stay alive. You will
regenerate back to 100 health very quickly. Then again, there are some things
that will destroy your character instantly. Watch out!
"Can I ask a question too?"
Feel free to ask me anything. If I consider it worthy, and I know the answer,
I’ll add it here.
-------------------------------------------------------------------------------
2. [Game Mode Tutorials]
------------------------
There are five different modes to play the game.
The first mode you will encounter is the Storyline Mode. You must play this
mode to unlock the other modes. (You have to get to level 13 in the main game
before you can play level 13 in the other modes.)
The next easiest mode is the "Advanced Mode". You can play any Bonus Room level
you have unlocked so far in "Advanced Mode". The levels have been changed in
this mode, and they are much more challenging.
The three hardest modes are all found in "Challenge Courses". Some of these
will seem downright impossible. To get Gold on some courses, you need to fire
ONLY TWO portals, or beat the level in ONLY TEN seconds! Yes. Difficult indeed.
but with a bit of thought, some trial and error, or with the ideas I’ll write
in this guide, you can figure them out! ;)
-------------------------------------------------------------------------------
3. [Tips for Beginners]
-----------------------
For the most part, this game is fairly linear. There will be places that you
can’t get to. This usually involves solving a puzzle. Sometimes it’s easier to
shoot a portal through a door. Sometimes you have to do it the hard way. The
best I can tell you is to keep at it. Really, you shouldn’t have to read this
guide for every level. The game is fairly straightforward. The only level I had
any problem with was level 18 (They didn’t fully explain the concept you need
to use in the last room of this level, so I was stuck). But now, I am thinking
with portals!
Something else to note is that you can’t place a portal on moving concrete.
When concrete starts to move, any portal that was on it will disappear. Keep
this in mind, as some of the Advanced Rooms exploit this fact.
Since you don’t start with a portal gun, keep an eye out for what we call the
"Portal Generators" on certain walls. They are vertical white strips that run
beside every panel that a portal will appear upon. Portal Generators exist in
both Blue-Portal and Red-Portal forms.
-------------------------------------------------------------------------------
4. ["Weapons Guide" - Using Portals for Fun and Profit!]
--------------------------------------------------------
You only get one weapon in the game. The "Portal Gun". There are two versions
of this gun, however.
When you start the game with no portal gun, GLaDOS places all the portals you
will need. When you get the "Downgraded portal gun", GLaDOS places all of the
orange portals you will need. The "Downgraded gun" only shoots blue portals.
Once you acquire the "Upgraded gun", you can place both portals, and none will
be placed for you.
There are a variety of weapons that will be used against you. I will list them
here, and they are also listed on every ’billboard’ before you enter the level.
* Aperture Science Weighted Cubes.
These can fall on you and cause damage. This is shown on every ’billboard’
before each level that has cubes. Though I have never found a way to kill
myself with spare cubes, it doesn’t mean that it can’t be done. Maybe if I
caused a cube avalanche...
* Energy Pellets.
These balls of energy are usually fired out of Energy Emitters, and usually,
the goal is to deflect or redirect the balls of energy into Energy Receptors.
Energy Receptors are usually wired to Platforms or Doors that will help you.
These Energy Pellets can also be used for knocking over turrets.
* Pools of Acid.
Do not fall into these. Normally, this feat is easy, but there are some rare
exceptions.
* "Friendly" Turrets.
These have a "Friendly" red laser indicating their line of sight. Their visual
range is about 45 degrees to either side, however. If you find yourself being
shot by a turret, duck and cover! Alternatively, you could portal yourself away
(Aim down, fire portal), but I find that takes too much thought. If I came from
somewhere safe, I make sure I can get back to it. If you can’t get back to it,
bring a weighted cube or two with you, at least, for cover. The only way to
stop a "Friendly Turret" is to knock it over, before it shoots you with too
many "Friendly Bullets".
* Cake?
Well, it’s listed on the billboard, but cake has never hurt me. ^_^
* Other?
There are rumours that there are other types of weapons to be found in the
Aperture Science Testing Facility that can hurt you! Are these rumours actually
true, or just fabricated? Are there weapons that can shatter glass? Can you use
them to your advantage somehow? Can they be fired through portals? Hmm!
--
How do you use portals "for fun and profit", you ask? Well, I think it goes
something like...
1. Fire blue portal.
2. Fire orange portal.
3. ???
4. Profit!
Some think step 3 involves videotape. Some say it involves learning Klingon.
I can’t say for certain, but it oughtta be pretty fun to figure out!
-------------------------------------------------------------------------------
5. [A Note on Techniques from an advanced player]
-------------------------------------------------
There are a few techniques listed here that are demonstrated in the early maps.
There are a few techniques here that are required to beat the game. There are
a few techniques here that only the advanced players know about. Hopefully
these will help you, before you get to the actual walkthrough and spoil it for
yourself.
Flinging: This concept is taught on the latter half of the course. It involves
placing one portal on a high-up wall, and shooting the ground with another
portal, just before you hit it. When you do, you will "fling" out of the higher
portal with high velocity, flying over any walls or gaps that might be in your
way. This technique comes in handy extensively in the bonus rooms.
Firing in Midair: There are two ways to do this. The flinging technique
described above uses this to your advantage.
"Bouncing": I haven’t heard anybody coin the term yet, but it involves coming
out of a portal (placed flat on the ground) with such velocity that you spring
up into the air. I dunno. "Portal-Bouncing" sounds nice. What do you think?
-------------------------------------------------------------------------------
6. [Aperture Science Test Course]
---------------------------------
In this game, you play "Chell", the silent female protagonist in an orange
jumpsuit. Is she a convict? Is she involved with Aperture Science? Well, let’s
find out!
The first few rooms teach you the basic concepts. Portals do not lead into
other dimensions. Portals lead you from one part of the Test Facility to
another part, usually within the same room. The computer voice, who you will
eventually get to know as "GLaDOS", seems to have the ability to create portals
wherever ’she’ wants. This works out to your advantage in the early rooms.
{Use the mouse to look around}
{Press W to move forward}
{Press S to move backward}
{Press A to strafe left}
{Press D to strafe right}
{Press E to grab or drop an object}
{Press Ctrl to Crouch}
{Press Space to Jump}
-------------------------------------------------------------------------------
Room 00; GLaDOS will introduce you to your life as a test subject. After a
minute of studying your clipboard and listening to the radio in your
"Recreation chamber", ’she’ will open a portal for you. At this point, you may
leave your cell. You will also see yourself walking through the portal, and
though disorienting, this lets you know that you are not in some other world.
You are in the same dimension, you are just outside your cell. An interesting
note; If you take the radio with you, and place it in the doorway to the next
room, the door will malfunction when it tries to close. ;)
The "Box on Button" concept is fairly simple. You place a box on a button, and
a door opens, or a platform moves. Interestingly enough, you can also stand on
a button to see what it does. Sometimes, you won’t even need a box. You may
only need to press a button once. Anyways, in this next room, you find a box,
and a button. Placing the box on the button will result in success.
If you needed a tutorial for this level, then I’m not sure you’ll do so well on
the later levels... :(
-------------------------------------------------------------------------------
Room 01;
This level may be a bit confusing, but it’s easy to stumble through. You start
out with one orange portal. Like all orange portals early in the game, this one
will not move, but the destination is constantly changing. The idea here is the
same as the last room. You need to grab the box, and put it on the button.
The difference is that the box and the button are in different rooms, totally
closed off from eachother. If you are quick about it, you can run into the box
room as soon as you see it, grab the box, and back out of the portal before it
changes rooms. If you are not fast about it, you might lose the box, or become
trapped until the portal comes back. No worries. When it comes back, now is the
time to step through, and wait until you see the button through the portal.
Rush in, show the button what a cube is for, and run back out before the portal
leaves you. If you are forced to suffer prolonged exposure to this button, do
not worry! You will have your cake eventually, and that’s all you need.
When you are finished here, just go through the door when you see it.
-------------------------------------------------------------------------------
Room 02;
[3 Cameras]
You finally have your portal gun! It is time to break Vital Testing Apparatus!
Okay, well, you don’t have your portal gun yet. There are a few steps to take
before you can get to it. First, wait for the speech to stop. Then go through
the door. Wait for the blue portal to appear. The portal gun will fire this
portal through the makeshift window. When you go through the blue portal, you
will come out on an upper ledge. Simply jump down, and grab your very own
Portal Gun!
{Left-Click to place a Blue portal}
{Press E to grab an object with the portal gun’s stasis field}
Hoorah! Now you can shoot... err... Blue portals? Well, still, that’s very
awesome. The power of the thing! You are bending space to your will! Here’s the
cool part. Stand near the orange portal, and shoot blue portals at any place
you can see. Shoot off to the left, and you can get back to the beginning of
the level by stepping through the orange portal. Look for a camera. There are
three of them in this room. Shoot a blue portal at the first one you see. Since
the camera is now ’attached to air’ through the portal, the wires and bolts are
cut, and the camera falls off the wall. GLaDOS doesn’t seem too happy about
your destructive tendencies. However, one of your mission objectives is to
destroy every camera you come across. Might as well get them all your first
time through.
Once you have successfully pruned the other two cameras from their native
habitats, feel free to go through the doors and leave the room.
-------------------------------------------------------------------------------
Room 03;
[3 Cameras]
"Mind the gap". This level is simple. It also again demonstrates the use of the
blue portal as both an entry point, and an exit point. Shoot the cameras off of
the walls when you see them. Place a blue portal anywhere nearby to get through
to the platform with the orange portal, then place the blue portal near the
door to complete the level. If you didn’t see the cameras, try looking up. ;)
-------------------------------------------------------------------------------
Room 04;
[2 Cameras]
Again with the boxes and buttons. This is simple. The orange portal is on the
upper level. The boxes drop into the lower level. Theoretically, you could put
a portal into the lower level, under the box, and it will fall out of the one
on the upper level. You could shoot a portal on the wall of the lower level,
and walk through the orange portal to grab the box. You could jump down to the
lower level, place a portal anywhere, grab the box and walk through it.
However you get the box, place it on the button for the door to open. Don’t
forget to shoot the two cameras off the wall before you leave!
--
Room 05;
[3 Cameras]
Before you walk into the room, shoot a portal at the camera. It will fall clean
off the wall. As you walk in, look to your left to find the second camera. Now,
you’ll notice two buttons. One block is on a high platform, and one is in a
pit. Shoot a portal under the block in the pit, and it will fall out the orange
portal onto the other platform. Shoot a portal near the floor to walk through,
grab the block, and put it on one button. Go back through the portal and shoot
a portal behind the other block while standing on the platform with the orange
portal. Go back through the orange portal, grab this block, and put it on the
other button. Go through the door. Shoot a portal on any wall here and fall
through into the room above. Knock the camera off the wall and exit the level.
-------------------------------------------------------------------------------
Room 06;
The "Energy Pellet into Receptor" concept is a little more advanced than the
"Box on Button" concept, and it was first introduced in the Halflife Series,
when the player used the gravity gun to fire these energy balls into receptors.
Basically, the Energy Emitter fires an Energy Pellet, and you place portals
constructively in order to make the Pellet reach the Receptor.
There are no cameras in this room since it has metal walls. The room is simple
as cake, however, just one portal is required. The orange portal is placed for
you, in just the right spot. Put a blue portal where you see the orange glow,
above the Receptor, and ride the lift to victory!
-------------------------------------------------------------------------------
Room 07;
Just like the last room, you need to redirect an energy ball into a receptor.
To make this easy, wait for the energy ball to bounce off the wall. It will
leave a charred mark where you need to place a portal. Once the energy pellet
is through, just put a portal on the ceiling above the conveyor. Jump through
the orange portal, and ride the conveyor TO YOUR DOO- I mean... To happy fun
times with cake. Did I say Doom? No, that’s got nothing to do with Portal.
Totally different game.
-------------------------------------------------------------------------------
Room 08;
In case the energy pellets weren’t painfully obvious... (If you haven’t been
hit by an energy pellet yet, keep up the good work!) This room features yet
another form of the Pellet Puzzle. This time, you need to place two portals to
get the pellet to where it wants to go. First, put a portal at the black mark.
Then, after the pellet goes through, hit the orange glow with a portal. The
pellet will bounce off of the wall, go back through the orange portal, and come
out straight into the receptor. At this point, the conveyor will start up.
Now, place a blue portal where it is easy to get to. Walk through to the
platform near the orange portal. Then, place a blue portal near the level at
which the conveyor will stop. You should be able to walk straight through onto
the conveyor with no problems. It will take you straight to the next room.
-------------------------------------------------------------------------------
Room 09;
The following test is impossible. You know, you pick up a block here, and try
to drag it through the fizzler and stick it on the button, but the block just
keeps getting fried! No matter how many times you try to drag it through!
Obviously there is no way to complete this test. Well, not without portals at
least. (Did you think you were getting away from room 09 without shooting a
single portal? FAT CHANCE! Ha ha.)
The "Fizzler" concept rarely comes into play. It is in this room where the
’Emancipation Grill’ (known to the Development Team as a Fizzler) is
introduced. Trying to take an item (such as a box or camera), through the glowy
blue particle field will destroy that object. The only objects that can pass
through unscathed are yourself, and your portal gun.
Anyhow... To beat room 09, place a portal where you can get to it, easily. Grab
the cube, and take it up onto the platform with you, near the orange portal.
What an interesting viewpoint! You can see right through the window into the
other room! Why... There’s concrete in that room! And concrete... Is good for
making portals! Shoot a portal into that room, grab the box, step through, and
you’re home free. Box+Button=Win!
Crazy Emancipation Grill. I think I lost a few teeth going through that time.
-------------------------------------------------------------------------------
Room 10;
[1 Camera]
There’s a lot of flinging in this puzzle, and there’s also... a hidden camera!
Can you find it? No? Aww. It’s right there though! Look up. And to the left.
Aha! Now, just walking through a portal won’t get you onto the staircase. But,
if you employ the force of gravity, there should be enough power to send you
through. Shoot a portal on the ground, jump in, and you’ll "fling" yourself to
the stairs. It might also work if you get a good head start or jump through.
In the next room, notice the portal on the extended platforms above you. To get
over the gap, you’ll need to fling yourself hard... And that’s why the pit is
so deep! You’re going to have to shoot a portal while you’re falling. So, look
straight down, step off the precipice, and shoot! The blue portal opens up, and
you "Fall" forward over the chasm.
One more room. This one has multiple levels. As you walk to the ledge, the
panels behind you will extend. There’s an orange portal at the bottom of the
pit. If you don’t have funneling turned on, now’s a good time as it might be
hard to hit the portal otherwise. When the panels behind you stop, shoot them.
Now, jump into the orange portal at the bottom of the pit. You’ll fling out to
the second level, and the panels will extend even further. Again, shoot them,
and jump into the same orange portal. You will probably come out upside down,
DO A BARREL ROLL, and land on your feet. This is because Chell is a cat.
Secretly.
-------------------------------------------------------------------------------
Room 11;
[1 Camera]... Keep an eye out for it!
You start in a room overlooking the main chamber. There’s no way into the
chamber at the moment, and GLaDOS will let you know that the floor is
dangerous. Looking down, you should see a gun that is shooting orange portals
onto different surfaces.
Wait, a gun that shoots ORANGE portals? OMG! Why... That’s a whole new game!
Don’t get too excited. Just shoot a blue portal on a wall, and wait for a
destination that has solid ground to walk on. Every third portal fired will be
in a small alcove. Step through. Notice the button on your left. Walk up and
press it. The door across the chamber opens, but there is no way to get to it.
Not in the three seconds they give you, anyhow. So shoot a portal through that
door.
When the orange portals come around again, step through into YIKES! There are
Energy Pellets in here! Well, there was a receptor outside, wasn’t there? Yeah.
The portal gun only hit three walls because the fourth one had a Receptor. So,
Shoot a blue portal at the black mark on the wall. Eventually, the pellet will
hit the receptor. You can peek through the portal to check its progress. Once
it does, the conveyor will start up. When the orange portal comes around to the
conveyor, jump through the blue portal... This is where the good music starts.
And you’ll soon see why.
{Right-Click to place an Orange portal}
{Left-Click to place a Blue portal}
{Press E to grab an object with the portal gun’s stasis field}
Grab the Fully Powered Aperture Science Handheld Portal Device. A button podium
will rise from the acid. Press it and shoot a blue portal through the door
above. Ride the conveyor back across the acid, shoot an orange portal at the
wall. Step through. Congrats! Your first orange portal!
-------------------------------------------------------------------------------
Room 12;
There are a lot of shiny steel walls here. The basic idea is the same as room
10 though. Simply place one portal on the outcropped panels, and shoot the
other one into the bottom of the pit as you fall.
On level 2, there is a higher set of outcropped panels. Jump into the pit here,
and it will fling you to level 3. Once there, two things will happen. First, a
cube will drop on a higher platform behind you. Second, a panel in front of you
will extend, and angle itself upwards. I’m sure you can guess what you need to
do. That’s right. Put a portal on the angled panel, and jump into the pit
again. Now you can grab a box from the fourth platform, jump down to the third,
and put that box on the button.
Jump down into the pit again (without any new portals) to get back up to the
platform where you got the box. GLaDOS will malfunction? But now you can leave
the level.
--
[NOTE: The next six puzzles have many different ways to win. Here, I will give
the most accepted (and probably lengthiest) solutions for each puzzle.]
-------------------------------------------------------------------------------
Room 13;
[3 Cameras]
Enter the room, and notice a camera on the wall to your left. There is also a
box on a grating. Though you can technically jump off the button to grab the
box, that is difficult to do, and takes many tries. So place a portal above the
grating, and one where you can get to it. Grab the box, jump down, and put the
box on the button. The door above will open. Shoot a portal through the door,
grab the cube, and go through the portal. Make sure to get the camera here.
In this room, there are two button platforms. One high near the wall, and one
low away from the wall. There is also an energy pellet emitter and receptor,
and a box on an unpowered conveyor. To power the conveyor, shoot a portal at
the black mark, and another portal at the orange glow on the ceiling. Now, fire
a portal off to the concrete area on the ceiling above the conveyor, and one
portal on a wall that you can reach to step through. Grab the box from the
conveyor, and jump off. Now, place one portal above a button, and drop a box on
top of it. Place a portal above the other button, and drop a box onto that one
as well. The door will then open and you can go through to find another camera!
That’s it for level 13... for now!
-------------------------------------------------------------------------------
Room 14;
Nowadays, I always breeze through room 14 using the two-portal technique. But
I’ll give you a break and describe it the right way. First, walk down the hall.
Turn left. Stairs will rise here leading you to... a Receptor? There’s no
emitter in sight! Hmm... Oh, hey, there’s also a box up here! Grab that sucker.
What? You can’t reach it? No sweat. Place a portal on the floor next to it.
Now, where can we build up some velocity. Let’s backtrack... Hey, the stairs
are gone! This is perfect! Shoot the other portal at the bottom of this pit.
Drop into it, and you’ll find you fling yourself upwards fast enough to get
yourself on top of the box’s pedestal. Grab the box, and jump down. And jump
down the stairs. Now head for the button. Hmm... That didn’t bring the lift
down, but it did open a door. Lets go through there.
Hmm, there are some lifts inside some acid? But why bother. Put a portal at the
end of the room, and send yourself through. Now here’s something interesting.
The Energy Pellet Emitter! Put a portal somewhere where you’re not going to be
hit by the Energy Pellet. Then put the other portal on the black mark. Keep
track of which is which, because you don’t want to come back here.
Now, if you want to skip the acid again, you’ll have to go through the portal,
so be aware of the energy pellet at all times. Once you get back to the main
room, put the correct portal on the glowy orange part of the ceiling, and the
lift will descend. You’re home free!
-------------------------------------------------------------------------------
Room 15;
[5 Cameras]
I don’t know why they say there are only 20 tests here. Some of these are
multi-layered. And some are multiple choice! So in this room;
Put a portal on the outcropped panel above you. Shoot the camera off the wall.
(It’s in the hallway.) Put a portal near the middle of the checkerboard pattern
on the floor, and fall through. You should fall through it twice, and fling
yourself through the large fizzler. Once you’re past that, shoot the camera
from the upper right off of the wall.
The next room requires speed and timing. There are two large fizzlers (these
erase your portals, btw...) and an emitter as well as a receptor. How you do
this one; First off, leave the camera on the wall, as it helps you to tell
which panels are on which sides. Now, before stepping through a fizzler at all,
shoot a portal at the black mark, and another one on the panels to the other
side of the camera. The energy pellet should travel through. Run through the
fizzler by the receptor, and place a portal on the wall where the pellet leaves
a black mark. Place the other one on the orange glowy part on the ceiling. Once
the pellet hits the receptor, the lift will descend. Take a moment to shoot the
camera off the wall, then step aboard the lift, and go up into the next room.
This one’s tricky. You know a portal goes on the outcropped cement, but you
can’t reach the checkerboard pattern on your good graces alone. So step into
the room to your left, shoot the camera off the wall, and jump into the pit.
Shoot the ground before you hit it, and you’ll fling out of the portal with
enough force to reach the checkerboard. Shoot *another* portal at the
checkerboard and you’ll fling out with enough force to clear the fizzler.
On this side of the fizzler, you have an outcropped panel and a checkerboard
that’s easy to reach. You need to be on the other side, so do the fling thing
and get over there. This side of the room is symmetrical. Where the flat part
of the wall has a black mark, put one portal. Put the other portal on the
opposite side, and the Energy Pellet should bounce off of one angled panel, go
through the portal, bounce off the other angled panel, and go straight to the
Receptor.
Do the fling thing again, to get yourself back over the wall, and then go
right... WHOA BOY HOWDY! Something’s not right with this tunnel! I’m not sure
the folks at Aperture Science Inc like you very much. Anyway, here is a good
place to test your portalling skill. Place one portal near the end of the
hallway, by the arrow sign. Place another on the wall next to you. Step halfway
through the portal and look for a conveyor. When one comes along, step out onto
it, and place a portal at the end of THAT hallway. You have two options here;
You can be impatient like me, and try to jump back through the portal you were
standing in, but that’s risky if there’s no conveyor there. You could do the
other impatient thing, and keep placing the other portal along the wall until
the conveyor you’re waiting for actually shows up, or you can do the smart (but
patient) thing, and ride the conveyor all the way back to the end of the tunnel
where you put your first portal on the wall. Whatever you do, keep doing this
until you can portal yourself into the final room of this level.
For the final room; The Receptor here is behind two doors. You need to redirect
an Energy Pellet, and then open both doors in order to activate the lift. The
easiest way to do this is with portals. So portal yourself up into one of the
rooms on the side. (...or take the lift. Spoil sport!) Each of these rooms has
a button podium, which opens one of the doors. From up here, first place a
portal on the black mark on the floor, and then one on the outcropped ledge.
Watch out, here, because if you don’t place these portals right, the Pellet
might ricochet off the Emitter, and then you might be in trouble when the
Pellet comes after you! So when you have those portals placed right, do the
following;
Wait until the Pellet travels down through the portal.
Place a portal in the far button podium chamber.
Place a portal in your podium chamber.
Hit your podium button.
Step through the portal.
Hit the other podium button.
If you timed it right, the Receptor should activate, and the lift to the exit
should come down! Congrats! Oh, and don’t forget the camera right above the
entrance to this room!

The first camera here is right through the door and WHAT? Live fire course
designed for androids?! I’m not made of metal! Help mee!
Okay, after you disable the first turret (all you have to do is knock it over,
You can pick it up and throw it and you can even drop a portal on it...), there
will be a metallic hallway to your left. Take your time, as the next turret is
pointed straight at you. After the metallic hallway, the second camera is also
on the wall in front of you. Looking through the new door to your left, you can
make a portal on the wall there and get through to cover virtually undetected.
Of course, there is a small time delay between the point the turrets see you,
and when they actually start firing. Technically, you could run diagonally
through the laser to cover. Anyhow, portal behind the next turret, and knock it
over with portals or by throwing it. Or just set it up so it can’t see you
because you won’t be back this way anyhow.
The next turret is such that you can’t run past it, but you can portal past it.
Don’t, however, since it’s guarding a camera, and you need that camera! You
need every camera, in fact. So portal the camera off the wall, and then portal
past it. You might also take this opportunity to knock over the turret by
sending another live turret at it through a portal. That achievement was easy,
wasn’t it? Now, after this tunnel, you’ll find your first clue that something’s
not quite right in the Aperture Science facility (As if you didn’t catch on
already)... The word "Help" is scrawled in blood in numerous places, and if you
manage to crawl behind the panels, you’ll find what appear to be very slum-like
living conditions. You can now use portals to drop these two boxes onto the
turrets in the hallway. Watch out though, because they can see eachother.
Once those two turrets are disposed of, portal behind the turrets in the next
room. Watch out for the ones through the door that can see you. Knock these two
turrets’ heads together. You’ll find a storage closet in front of you, with a
malfunctioning cube-transit tube and a pile of boxes. Feel free to portal these
boxes onto the turrets in the next room. Pry the fourth camera off the wall in
this room. Then use one of the boxes here on the button.
When the door opens, a turret will be looking straight out of it. Don’t tell me
you didn’t see that coming. Anyhow, portal behind that turret, and then drop it
back through the portal so it falls over. Pry this camera off the wall, and
portal into the last room. If you do it right, you don’t even have to worry
about the final turret. Just walk past it, and exit the level.

So now you know. Everyone has been talking about this "Companion Cube". And now
you have your very own! You’ll have your cube forever! Yay Cube! You can even
find desktop wallpapers, avatar images, and papercraft for your companion cube
on the internets, if you look hard enough.
I’m going to show you how to do this level with TWO portals. =D
Use the cube to climb to the top of the platform in the next level. Place it
near a high wall, jump{with Space} to the top of the cube, and then once you’re
up, grab {with E} the cube. You may need to crouch {with Ctrl} to reach the
cube to grab it. Now here are some energy pellets. To protect yourself, walk
holding the companion cube in front of you. The pellets will bounce off the
cube, and you should be safe. Once you get to the end of the first hallway,
wait until the energy pellet passes you, and place a blue portal on the far end
of the hallyway.
Grab the cube again, and walk down the second hallway with the same tactics. If
the energy pellet breaks, walk backwards "dragging" the cube behind you. Once
you get to the end of this hallway, shoot the camera off the wall with an
orange portal[if you’re not doing the 2-portal challenge]. Go through the door
to your left, and shoot the other camera off of the wall with another orange
portal[if you’re not doing the challenge]. Grab your cube and jump down.
Watch out for Energy Pellets! This is where they will all go. Place the orange
portal on the outcropped panel down here. Run through the door behind you (the
one with the closed door behind it) Do not put your cube on the first button.
Head left, and put your cube on the button atop the shelf. Now go back to the
first button, and wait for an Energy Pellet to pass. Step immediately on the
button, and the pellet should pass through both doors, and hit the Receptor.
Now, go back and get your cube. Watch out, because the Receptor will not have
shut down. They turn off in a specific order, and this is important. Use your
cube to deflect the next Energy Pellet into the receptor to your left as you
leave the two-button room. You may have to get your cube angled the right way,
so try putting it on top of the outcropped panel, and catching it while it
falls to get it angled just right. After that Receptor is happy, go into the
small room to your left, and use your cube again to deflect the Energy Pellet
into the Receptor.
Go back through the portal, run down the hallways with your cube, and go
through the door to your left again. The lifts are now up. Jump to the first
one. Get a running start and jump to the second one. Do the same for the third
one. Turn right, and jump to the platform. Put your box on the button to open
the door. Go through the door to press the button to open the furnace. Run back
and grab the companion cube, and get ready for a tear-jerking scene as you drop
it into the furnace!

This level is full of fun. But if you think it’s hard now, just wait until you
try it on Advanced. Okay, so lots of acid. Portal over it. Some more acid. Put
a portal on the center of the ceiling to your right. Or take a break, and look
to your left to find another live-in space...
So how do you get to this portal? Well, you’ve only got one reachable area of
concrete, so you’re going to have to jump down into it, and hope you don’t miss
and hit the acid. Also, when you come out of that portal, you have to aim,
because there’s acid on either side of it. The test goes on like this... Portal
to the platforms. Eventually, you should come to a closed door, and a button on
a higher ledge. "Fling" yourself to this ledge with a few well-placed portals.
In here, there’s a button podium. Press the button and walk through. The
turrets won’t shoot you... yet. Just stay to the left. Now, there’s an Energy
Pellet Emitter here. And there are four very black marks on the wall. Fire an
orange portal at one of them, and a blue portal at the point where a laser
meets the wall. You should see the Energy Pellet fly through the portal and
knock the turret off of the platform. Do this for all four turrets. It will
make your life a lot simpler. Also; Shoot the camera.
Now, you need to get an Energy Pellet into the Receptor to power the lift. To
get to the Receptor, you have to open a door. To open the door, you have to
place a portal on the wall that you can reach, and one high up near the podium
button. After you’ve tried this out once or twice, and you’re fairly satisfied
you can do it on command, now’s the time to test out your prowess. Shoot a
portal on the outcropped panel straight across from the Receptor door. Shoot
another portal on one of the very-black-marks. Once you see the energy ball go
through, IMMEDIATELY place your two portals at the podium button, leap through
and press it. If you did it right, the Energy Pellet will enter the Receptor
and the lift will be powered! Now is the fun part! You’re almost to your cube!
[If this last part was hard, there’s a really easy way to get the Energy Pellet
into the Receptor; Simply portal yourself inside the receptor room. Once you
get stuck inside that room, the door will open, and you have all the time in
the world to let the Pellet hit the Receptor. You don’t even have to press the
button at all! - thanks to ’Zater Roflcakes’ for pointing this out.]
Ride the lift across the acid lake. Jump down to this button. This is the
button that activates the doorway out of here. What you’ll need to do is place
a portal on a panel that is not a part of the doorway. Press the button. If the
portal disappears, that is a part of the doorway. Shoot a portal somewhere
else. Now, behind you there is some concrete. Shoot the other portal there, and
jump through. Make sure you have enough time to scurry back out the doorway.
NOTE: If your portal is ON the doorway, you WILL fling yourself into the acid!
Now that you’ve made it back out of this infernal room, you’ll obviously be
asking "Hey, where’s my box?!"... Well, you have every right to. I’ll tell you.
Press this button. Run out. Place a portal on top of this angled panel. Now,
look off to your right. There is a checkerboard platform down there, right
above the acid. TRUST ME. Okay, now that you see it, jump down and shoot the
other portal before you hit. If you were fast enough, you should fling yourself
across to where the boxes are. Grab a box, and jump down to the conveyor. You
now have two options, depending on how safe you want to be with your box. First
you could ride your conveyor all the way across the lake of acid and put it
safely on that side, then riding back to hit the button to open the door, or...
you could bring the box with you when you hit the button to open the door.
Either way, make sure you have the box as you go through the doorway. Now put
it on the button, and you’re home free!
Oh, did I say free? I meant you have to do THIS puzzle next. There are four
platforms, and one angled panel before the exit (and the final camera). Simply
shoot the first platform with a random portal. Now, off to your left, there
should be a deep pit with concrete at the bottom. Jump into the pit, and shoot
the opposite portal at the floor before you hit it. You will fling upwards out
of this portal.
This is the part I had trouble with. See if you can figure it out on your own,
before I tell you...
...
Okay, now, you can’t make it to the next platform by trying to angle your way
there. You have to shoot it with a portal. So at the apex of your ascent, shoot
a portal at the next platform. I notice that I always come out of the next one
facing backwards. So before you hit the portal below you, turn around. Now,
you’ll come out, and you should see the next platform. Shoot it with the
opposite color than the one you just shot. When you go through this portal, you
should be looking at about 45 degrees behind you. So look toward the window to
your right. When you go through the portal, you’ll be looking down to your
left. Shoot a portal at that ledge. For some reason when you come out of there,
you’ll be facing the ceiling. Get the jump on this by looking up as you go in.
You should be able to spot the tilted panel now. Shoot the opposite color at
that one, and it will fling you across to victory.
Remember to shoot the camera!

At last! The hour of your cake is nigh!
Walk in. Notice the billboard. Look! Cake! Yay!
To your right, as you enter, there will be a camera. Shoot it.
The next puzzle is fun. An emitter is shooting straight down, and the Energy
Pellet is bouncing off of a slanted panel. Shoot a portal onto this panel, and
onto the panel on the opposite side. When the Pellet is on the Receptor side,
get rid of your portal (by shooting it again), and the Pellet should bounce
straight into the Receptor. This will power the conveyor. And... Oh, look, it’s
going the right way this time! Someone up there likes you!
Feel free to ride the platform, or just portal across to the grate. Ride the
platform some more or portal into the next room. There’s a button here that
opens a door for a split second. You’ve encountered this type of puzzle before
in level 11. Put a portal on the other side, where you can step across to the
platform. Make sure you kill the camera here. Now, step through the portal when
the platform comes around. There’s no turning back now! Exciting! Uh oh! That’s
an Energy Pellet bouncing back and forth making all that racket! Well, let’s
liberate it. Shoot a portal behind the camera at the end of this hall, and
another portal on the black mark on the wall. Oh, hey! That was your last
camera! Good for you! Now, the Energy Pellet will be free, flying far above
you. Get rid of that portal so the ball doesn’t come back.
I’m so excited! I can almost taste the cake!
Now here’s the last puzzle before the cake. You see a cement wall in front of
you. The cement wall doesn’t want you to have your cake! Well, you’ll see about
THAT! Shoot a portal on the wall to the left, behind the cement barrier. Then
shoot a portal ON the cement barrier. Now, when half of your conveyor is past
the barrier, jump through.
Looking forward, there is a GIANT billboard exclaiming your victory. AT LAST!
CAKE!

Allright, I doubt it was any surprise. GLaDOS did tell you earlier didn’t she?
Well, I’m sure you know what to do here, but it’s not so obvious to some
people. The far wall is entirely concrete. You don’t want to be baked, (I hope)
so portal across. The walls beside you are also concrete. Put a portal there,
and jump through. Cross your fingers! Now that you are here, GLaDOS isn’t going
to do you any favors. So here’s where the walkthrough really begins.
--
The Escape;
Fling yourself across the cake room. Turn left. Pick up a barrel. I know, it
seems weird, but it’s only when I picked up the barrel that I got the ’party
escort submission position’ achievement. Now, turn right. Go up the stai-...
Nevermind, portal up the stairs. Go through the door. {Press E to open it}
Go up these stairs. This door is locked. Portal through the fence. Open that
door. Portal behind the fans, and under your feet in the concrete area. Watch
out here, the fans will hurt you. Portal up across the acid-filled gap. See
that catwalk near the ceiling? That’s where you want to be. Put a portal really
high on that side of the room and one behind you. Try to land on the catwalk.
Turn left to see a hidden Powerpoint presentation which shows that GLaDOS was
meant to be a De-icing component for fuel systems. I think someone interpreted
"icing" the wrong way. Also, you can run around and look at the old levels you
played through, from the other side of the frosted glass! If your textures are
set to high, you should also be able to notice what looks like a garbled Cake
Recipe on all of the monitors. Anyhow, no time now, go back across the catwalk.
Head down the stairs. It looks like someone scrawled an "Exit symbol" here...
They scrawled it in something red. I don’t think that’s marker. I hope I’m
wrong. Anyway, above where the exit symbol is, place a portal on the very top
of the wall. Fling yourself across to the next area. Turn left. Go up the
stairs, and go up some more stairs. You should find a broken Cube Transport
Tube here. Jump in!
Hey, this level looks familiar! You don’t need a cube now that you have both
portals. Just stand on the button and portal through the door. Hey! Where’s
the elevator! Jump down. Place a portal at the bottom of the elevator shaft,
and place another portal on the concrete area you can see from here. You should
drop about 2 feet. Crouch {Press Ctrl} and crawl out of this area towards the
steam lifts that push you upwards. Stand on the topmost one, and shoot a portal
to the top of the platform you just crawled out from under. Run back around,
and crawl under the platform again. You should be able to jump up through the
portal underneath the platform, and out of the one on top of the platform. Now,
ride the horizontal steam compressor toward the exit from this room. Shoot a
portal to the other side of the grate, and then go back to the cement platform
you jumped through. Place another portal here to get to the other side of the
grate. Place a portal high up in this small room, and one down low. You should
be able to jump from the higher portal to the exit.
-------------------------------------------------------------------------------
[Loading] (You didn’t notice it before when there were elevators did you?)
You will enter a large room with five large presses. The two at the end will
crush you (like they’ve already crushed the ceiling). Standing on the middle
platform, you should be able to see a concrete wall at the top of the broken
ladder. Put a portal there, and jump down and put a portal near the floor. Run
down the stairs to find a small room with two small presses. Looking up, you
should be able to find a place for a portal. Put a portal there, and one on the
ceiling where the presses are pressing. Yes, this is a little dangerous, but
it’s the only way. (You don’t want to backtrack, do you? Oh, well, fine. What
do you need this guide for anyway!) Sorry, GLaDOS’s pessimism is getting to me.
Place a portal high up, and slingshot yourself across this room. Don’t bother
with the pumps in the next room. Portal past them. Also portal past the two
presses which will inevitably press you if you don’t portal past them.
Place another really-high-up portal, and a low one on the wall. See if you
can’t stand on a press, and shoot a portal into the next room through the
fence. Portal into that room, and you should find a glass tube you can walk
along. Walk along this until you see a glass tube down below. Jump down, and
walk along this tube until you come to a room. You want to get to the top of
this press, so shoot a portal above where it is crushing, and go back along the
tube to where the walls are made of concrete. Shoot a low portal, and jump in!
Hopefully, you land on the press, and not IN the press. Run along the press and
exit to your left. Jump over the rails and down the hole.
-------------------------------------------------------------------------------
[Loading]
Walk forward until you see six large presses. Step on them, and they will let
you into the ambus-(ahem) into the room below. You might want to grab a barrel
unless you’re confident with your portals. One by one, doors will open. Each
door has a turret behind it. Knock them over or portal them out of comission.
The final door has a hatch. Shoot a portal through it.
In this place, you can find the only ’broken turret’ in the game. It’s a sad
sight. When you want to get out, find a place that there is no railing on the
catwalk above, that you can portal up to. Portal up to it. You should find a
small room with a hole in it, where an active turret awaits behind a door. This
turret is not broken! Jump down and pick up the turret. When the door opens,
throw the turret out.
Jump out into this room, and use the slanted platform above you to fling
yourself up and to the exit. As you walk down the hallway and through the
office to the next area, GLaDOS will explain how this is your fault. Ignore her
and open the door. Press the button on the podium here and you will be
introduced to a new foe...
This guy is fairly slow acting. He shines a laser at you, beeps a few times,
and shoots a rocket at you. You step out of the way. He shatters the glass.
Well, there’s a lot of glass all over the place. See how much of it you can get
him to shatter. Shatter the glass between you and him. Shatter the glass on the
other side of the room. Place a portal in this room. Run through the glass he
shattered for you, and go through the next door. Down a little hallway and
through another door, there will be more glass. Place the opposite portal here,
and stand in front of it. Normally I wouldn’t say "Stand in front of a rocket
launcher" but there are rare exceptions. Okay, so he shattered the glass for
you. Place a portal on the floor under the Cube Transport Tube here. Jump in.
Get him to aim another rocket at the portal there. It should shoot straight up
into the cube transport tube, and if you’re lucky, a cube should pop out of the
portal for you! Take this cube and run back down the hallways. Use this cube as
a step to climb up into the air vent.
Crawl through the air vent, and shoot a portal down through the fan blades.
Crawl back through the vent. Place another portal, and go through.
Next you will have to portal yourself across a river of acid. Straightforward.
[Loading] (This is the last one, I promise!)
After you get past acid river, portal yourself up through a grate. If you’ve
taken your cube this far, I applaud you, but it won’t help you jump out of the
river of goo. That’s why you have your portal gun! Portal yourself up, and get
ready for the fight of your life!
-------------------------------------------------------------------------------
[Turret Ambush]
Doors all around you will open, and you will be defenseless. Oh, wait, what am
I saying, you have a portal gun! Portal behind each turret in turn, and kick it
out of its place. If you haven’t done the ’knock over a turret with another
turret’ accomplishment, try it here. I think you have to use portals to get it.
Anyhow, once all the turrets are out of comission, you’re going to want to
fling yourself using the slanted panels, so portal into a high-up alcove, and
fire a portal at one of the slanted areas. Portal through it, and portal when
you hit the ground. You might also be able to get the accomplishment called
’Long Jump’ in this room, with some creative jumping. So anyhow, once you fling
yourself out of the highest slanted panel, you should end up in a larger alcove
and two more turrets will ambush you. Portal them wherever you want them.
Now, back where the turrets were... How can you get up enough speed to jump up
through that hole in the ceiling? Well, there is a really tall room you just
left. Place a portal on the floor here, and use the height of the last room to
fling yourself upwards to the next area. Here, portal yourself up to where
you’re supposed to be, and then take a casual stroll down the catwalk (it was
far above the turret ambush room before) to the door. Open the door, and walk
through the Aperture Science Main Lab. Prepare yourself for the boss fight of
the century! What’s that? You didn’t bring any firearms? Aw, shucks.
-------------------------------------------------------------------------------
[GLaDOS]
The giant grape-looking thing in the middle of the room is GLaDOS, the Genetic
Lifeform and Disk Operating System, also capable of removing ice from your fuel
injectors. Don’t ask me how. Probably with rockets. Get a general feel for the
room. You have time. On the left is a button podium. The button opens the
Emergency Intelligence Incinerator. That’s a handy thing to have in a room with
a rogue AI gone wild, isn’t it? Remember, the fast way to get around is with
portals, since the whole room is practically made of concrete. You might want
to keep one portal on the far side of the room (to the right of the
incinerator) on the wall facing GLaDOS. You might as well leave it there for
the entire fight. If you’ve gotten used to left-clicking to place the important
portals, like I have, and rightclicking only when you need it, you might just
make this the orange portal.
Anyhow, to get this all started, GLaDOS will malfunction, and her Purple AI
module will fall out. Place a blue portal over near the button podium shelter.
Grab the Purple AI module, and head through the orange portal. Drop the AI
module, press the button, pick up the module, and head back through the blue
portal. Turn right, and place the Purple AI module into the Incinerator.
Uh oh! GLaDOS explains that the purple sphere was her morality core! Oh well.
I guess the morality core was the only thing standing between you and toxic
nerve gas. You now have five minutes left to live. To make matters worse, now
they’re firing rockets at you! Better hope you can find a way out of this
quick!
Place a blue portal underneath GLaDOS, and stand in front of the Orange Portal.
The rocket launcher will shoot a rocket (which you dodge) through the portal,
and another AI module will pop off of GLaDOS. This one seems to be "Curiosity".
It is yellow or orange or something, depending on your video settings. Portal
up to it and grab it through the orange portal. Portal back to the button and
press it. Run back through the portal, and destroy the Curiosity Module.
Fire another rocket straight up into GLaDOS’s core. Her blue module will pop
off. This one seems to have cake recipes stored in it. To get to it, you need
to shoot a portal fairly high up, in order to get to a glass platform near the
top of the room. Grab the module, jump down, and portal yourself to the button,
and then to the incinerator. Do away with this module. One left!
GLaDOS’s main module seems to have problems. It is a scary red module. Do the
same "Rocket Technique" to dislodge the module from the control core. Place
another high-up portal, or do some fancy portal-flinging to get to it.
{Press E} to grab it out of midair. It will snarl and growl and yipe and make
all sorts of fancy scary noises. That it is red makes it that much more
ominous. Throw this module into the incinerator.

7. [Advanced Mode]
-------------------------
I have completed all six of these rooms. They are grossly evil parodies of the
rooms you encountered during the last half of the storyline. Namely, room 13
through room 18.
Room 13 Advanced; [ADV13]
There are no boxes in the first room. This means two things. First, you must
stand on the button yourself and portal through the door. Second, once through,
you will have to acquire the box in order to open the second door. So portal
the Aperture Science High Energy Pellet into the receptor, and then portal
yourself onto the conveyor to get the box. Since the floor here is made of
acid, you must either jump down to the metal platform and take your chances in
leaping to the nearest wall, or jump from the conveyor to the platform beneath
the second door. You can put a portal on the wall, here, in order to get to the
higher button safely. Portal the block onto one of the buttons and step on the
other button. Then portal through the door to win!
Room 14 Advanced; [ADV14]
This chamber is nothing special. It is specially formulated so that you have to
solve it the way the programmers intended. You cannot use the 2-portal method
here. (However, the Room 14 Least Portals Challenge is quite the opposite.)
So, put a portal near the cube pedestal. Put a portal at the bottom of the
rising-stair-pit. Jump down into the pit, through the portal, and pop up onto
the pedestal to get the box. Put the box on the button. Go through the door.
Portal across the acid. Put a portal in the energy pellet room, and put the
opposite portal above the Energy Pellet Receptor back at the top of the
rising-stair-pit. Basically, follow the exact steps I have listed earlier to
beat this room in the normal game.
Room 15 Advanced; [ADV15]
Okay, I’ve seen video footage, it’s apparently possible to fling yourself past
the first room here, even though the high panel and floor panel are diagonally
skewed from eachother. Who knew! The method I used was completely different,
and probably easier. The method I used also exposes what may be a bug in the
game. Put a portal on the ceiling, and one on the floor (in order to create a
’Terminal Velocity Loop’). When you step in while looking down, "Portal Funnel"
will keep you falling into the portals. But if you look anywhere else, the
Portal Funnelling will not work. This means you have to be quick about it.
Shoot a portal (the same color as the ceiling portal) on the extended platform.
You should fling out and over the wall.
The next room should be easy. Put a portal on the black mark and one on the
wall to the right of the black mark. When the energy ball goes through, run
through the fizzler behind you, and put a portal on the wall to your right. Put
another portal on the wall right before the energy ball hits it. Run through
the fizzler to your left after the ball goes through the last two portals. Now,
put a portal on the ceiling where the orange glow is, and one last portal on
the wall before the ball hits it. The ball should drop into the Receptor. Note;
You have to get this right the first time. If the ball bounces even once, it
will fizzle out.
Enter the lift, and turn right down the hallway. This next test is impossible.
...
Okay, no, I was just kidding. ;)
A portal goes near the fence, in the checkerboard squares. You need to build up
enough energy to hop over, however, and you can’t do it by just jumping into
the pit. You have to fall into the pit from the top. So enter the room to the
left, and put one portal on the ceiling. Go back out into the big room, and
step into the checkerboard portal. As you fall into the room, place the same
colored portal that’s on the ceiling on the floor instead. You’ll now barely
have enough speed to hop over the fence.
Now, if you can’t get past the acid pits without activating the conveyors, then
here’s how you do it. Fling past the fence. Now there are two flat walls here,
right in the corner. Place a portal on both of them. The first should be where
the black mark is, and the second should be on the wall perpendicular to it.
To the left, right across the corner. What will happen is that the Energy
Pellet will bounce off of the diagonal panel, go through the portal, and come
straight back out through the fizzler, bounce off of the two diagonal panels
on the far side of the room, come back, bounce off the two diagonal panels on
the right, and bounce straight back into the Receptor. Fun, eh?
Portal through the acid hallway in the normal fashion (See the game walkthrough
above if you’re not sure how), and then, when you reach the next room, it is
also a lot like the game walkthrough. It’s a lot more time-critical, and there
are a lot more metal-panelled walls. Just jump down to the floor and portal
through the concrete on the ground to get to the second button in time. Really,
the challenge here is to get through without using the "Room 14" trick of
"Bunny-hopping" to the exit lift. Yes, you can technically do that. Yes,
exploiting this fact helps you in the Challenge rooms. Yes, you can also avoid
placing those portals by crawling along the wall. Yes, there’s a youtube video
with more details.
Room 16 Advanced; [ADV16]
This level is fun. There are many different ways through, but we’ll see if I
can’t get you there fast. I’d say portal past the first turret. Takes the least
amount of time. Alternatively, get on top of the turret cage, crouch and crawl
through, and try not to get shot in the back. Portal behind the second turret.
Portal under the third turrets lasers. Grab the two boxes here. Crouch. Put one
"in front of you", and drag the other "behind you". Basically, keep one box
between yourself and either turret in the next hallway, at all times. Whichever
one you’re holding, you will be ’seen’ through, but even though the turret
shoots at you, it can’t hit you through the box if you are crouched and holding
the box in front. So, back into the box "in front of you", and keep the box
that’s "behind you" such that it’s always between you and the turret you’re
facing. Back up all the way until you can portal yourself into the box room, or
into the 2-turret room. I’d recommend the box room, but it’s your call. Once
you’re here, portal yourself some boxes. You’ll need one to keep between
yourself and either turret in the next room, and you’ll need to put something
on the button. Good luck with that. Once the door is open, you should be able
to portal straight into the final room from outside the door, bypassing both of
these turrets. Congrats!
Room 17 Advanced; [ADV17]
For the most part, this is just like the Companion Cube level, except that the
Heartless Sphere can roll out from under you. Oh, and it’s difficult to guess
just which direction an Energy Pellet will be deflected. So let’s go! Use the
sphere as though it were a cube, and jump up the steps. Put a blue portal on
the black mark at the end of the first hallway. Hold the sphere out in front of
you while walking down the hallways. Keep the sphere between you and the
pellets. Jump down. Put the orange portal on the outcropped panel. Enter the
room with two doors. There is now a button on either side. You can use your
sphere as a stepladder to jump up onto a button. This is the easiest way to
realize when it’s time to run over to the other button. Anyhow, grab the
sphere, stand on the button, and wait until the Pellet is between the two doors
before jumping down towards the other button, and putting the sphere on it. One
down, two to go. Grab the sphere. Keep in mind that the Pellet will still come
out of the same portal. You might want to replace the portal up and to the left
of the outcropped panel, so the pellet comes out closer to where it should be.
Deflect it with your sphere so it goes into the Receptor here. One last pellet.
Go into the pellet room and... OMG! Who put that glass wall there! Anyhow, the
easiest way I’ve found to do this is to deflect the pellet at the steel wall to
the left of the Emitter, so that it bounces upwards, over the wall, and back
down into the receptor. Good luck here, because it’s a lot harder than the
others. After that’s done, you can portal behind the outcropped panel in the
lift room to see the secret "Companion Cube stalker" area. When you’re done
with that, portal back up to the newly raised platforms, jump across, and go
left. There’s a new room that assumes you’re going to fling through with your
"Companion Sphere". Well, you’re not. Place one portal on the left wall over
the pit. This will give you a good view of the concrete wall on the other side,
through the hole in the glass. Put another portal where you can easily get to
it. Step through, and shoot a portal onto the other side of the glass. Now take
your companion ball, and step through to the portal. From here on out, it’s the
same as the normal walkthrough. Only, it’s a sphere instead of a cube that you
will be forced to fry.
Room 18 Advanced; [ADV18]
And you thought the last levels were impossible. Okay, I’m sure you know how to
fling across to the first platform. Put a portal high up on the wall, and one
on the floor beneath you. Look down and aim for the portal. While you’re
flinging yourself, however, you need to shoot a portal on the top of the ledge
to your right. That’s right, you have to think ahead, and put a portal on the
floor there WHILE you’re flinging. Not too big a problem, but trying to get
through that portal without falling back out into the acid will be fun.
Once there, there are a few different ways to do this. My way involved shooting
a portal right above the steel block outcropping below the next platform. After
that, portal yourself up to the lowest platform. From there, you should be able
to see the outcropped panels, and you can fling yourself up and over to the
button. Enter the turret room. These turrets are more difficult to get rid of,
since there is no energy ball! Luckily, the conveyor is already working though.
Also, notice the platform in the acid has moved. These turrets also don’t seem
capable of being knocked over by other turrets shooting at them. You’re going
to have to get yourself to their platforms somehow. This somehow could involve
flinging, and it could also involve luck. I managed to complete the room after
knocking off only two turrets.
First, the far one on the left can easily be flung to by placing a high-up
portal in this area, and jumping before entering a portal on the floor. Then,
the close one on the right can be knocked off its platform easily by dropping a
turret through a portal placed on the wall above the platform. The far one on
the right doesn’t really matter much, and the close one on the left can be
avoided by crouch-crawling to the conveyor. Once it starts shooting at you on
the conveyor, though, you’ll have to run and jump across to the button podium
area.
Alternatively, you can follow the advice of a guy calling himself ’Inferno
Rapist’, and portal past all the turrets. In his own words;
"you can make a portal on the left wall, as far as you can make a portal, and
jump through and land on the part of the wall that is sticking out crouch
behind the wall that sticks out, and make both portals down on the platform by
the water. jump through the one closest, and if you’re lucky you will fly up
onto the area with the cube. go back and move to where, the sentries can’t
hurt you, make a portal across the room, to the safe area on the right, drop
the cube on the platform where the other portal is, hopefully, the cube wont
fly off into the water.(didnt happen to me) jump through, but right when you
fall through the portal, hold down so you dont fly off the edge. repeat the
first process to get to the switch, then get back up through a portal."
Sounds tricky, but you never know. It might work for you!
-------------------------------------------------------------------------------
8. [Challenge Courses]
---------------
Again, these courses are rooms 13 through 18. The idea of the courses are that
you must complete each course using a small number of portals, a small number
of steps, or simply, the quickest time possible. You’d be surprised on how much
you panic when you’re working under a time constraint. You forget how to place
portals. You forget how to put buttons on cubes. You forget how to pick stuff
up. You get all jittery. You curse like a sailor. It’s all in a day’s work,
however, as once you have the Science Awards, you can brag to all your friends.
Listed here are the absolute best scores I can find out how to accomplish. If
you have tips on how to best these scores, please send me a message. In all of
these courses, remember; Quicksave Often! When it is important, I will put a
R or B near the portal number, to denote that a portal should not replace a
portal that has already been placed.

-------------------------------------------------------------------------------
Least Steps Rooms; [LSR]
This section is incomplete. Doing least steps rooms is not too difficult, as
you have no time constraints, and no portal constraints. The thing to remember
is that jumping usually means two steps; one step to jump off of the floor, and
one when you land. Directing your movement in midair takes no steps. When you
create portals, make sure to portal yourself as far through the level as you
possibly can. Also, straight out walking is more advantageous than jumping, in
most scenarios.
My advice would be; watch the speedruns for these rooms as they appear on
youtube or portalwalkthroughs or one of the other fine sites hosting them. The
information for completeing these rooms in the least number of steps should be
fairly similar to what you see presented in the speedruns. It’s a hard concept
to describe in a text-only FAQ, or else I would. If you have any ideas on how
to describe it, send me a message, and I’ll think about adding your ideas here!
-------------------------------------------------------------------------------
Least Time Rooms; [LTR]
This section is incomplete. Doing least time rooms doesn’t seem like it should
be too difficult, but you would be surprised how jumpy you get when you’re
under the pressure of a time constraint. All in all, you’re likely to get
so frustrated, you’ll purposefully jump into that pit of acid, just to take a
relaxing dip. Well, don’t give up. You have a portal gun! You have all the time
in the world. Try doing the level at a very slow pace first, and then try it a
little bit faster, each successive time. Once you’ve bested a level about 5 or
6 times, it should be a breeze to breeze through.
My advice would be; watch the speedruns for these rooms as they appear on
youtube or portalwalkthroughs or one of the other fine sites hosting them. The
information for completeing these rooms in the least amount of time should be
fairly similar to what you see presented in the speedruns. It’s a hard concept
to describe in a text-only FAQ, or else I would. If you have any ideas on how
to describe it, send me a message, and I’ll think about adding your ideas here!

* Lab Rat: Acquire the fully powered Aperture Science Handheld Portal Device.
You get this achievement in level 11.
Simply pick up the orange portal gun to complete this.
* Fratricide: Do whatever it takes to survive.
You accomplish this achievement in level 17.
Simply destroy your companion cube when instructed. (NOOOOOO!)
* Partygoer: Make the correct party escort submission position decision.
You accomplish this achievement in level 19.
After you portal out of the firepit, fling yourself back across the firepit
using a very high portal. The achievement didn’t register for me until I picked
up the barrel at the end of the hallway to the left.
* Heartbreaker: Complete Portal.
You accomplish this achievement in level 19.
Play through the rest of the game.
* Terminal Velocity: Fall 30,000 feet.
This one is simple. Set one portal on the ceiling. Set one on the floor. Make
sure "Portal Funnel" is checked in the options. Now, look down, and jump in!
Mute the sound, and turn off the screen. Take a break from the computer. Make
yourself a sandwich. Eat the sandwich. Watch Doctor Who. Paint the fence. Fix
the car. Take a trip to the mall. 30,000 feet is a LOT higher than it sounds.
Consider: The typical hallway is 10 feet tall. You’ll have to fall through the
portals 3,000 times in a normal hallway. Some people say that taller rooms are
better for this. Well, if you turn your graphics detail way down in the options
then I don’t see the difference. Just make SURE that you are facing down...
Portal Funnelling doesn’t work if you are not facing down, and therefore you
will not achieve Terminal Velocity if you are not looking downwards.
(Special thanks goes to Renato Marchi for having me revamp Terminal Velocity)
* Long Jump: Jump 300 feet.
The best place to accomplish this feat is in level 19.
Once you reach the turret ambush room, you are in the right place. Experiment
with distance jumping, and you’ll get it... Eventualy...
* Cupcake: Beat two Portal advanced maps.
* Fruitcake: Beat four Portal advanced maps.
* Vanilla Crazy Cake: Beat all six Portal advanced maps.
Read the "Advanced Mode" section above for more information.
* Basic Science: Earn bronze medals on all Portal challenges.
* Rocket Science: Earn silver medals on all Portal challenges.
* Aperture Science: Earn gold medals on all Portal challenges.
Read the "Challenge Courses" section above for more information.
* Camera Shy: Detach security cameras from the walls.
Section 6 of this guide has a list of which rooms have which cameras. Just
keep an eye out, and don’t leave a level until you’ve knocked off all the
cameras. There are 33 cameras in total, and 3 are in level 19! Don’t worry
about the ones you see in levels 00 and 01. You can’t get them anyway.
* Friendly Fire: Knock down a turret with another turret.
You are most likely to accomplish this in level 16.
Knock over one turret with another turret. Both turrets must be alive. Another
good place to accomplish this is level 19, in the turret ambush room.

10. [Cheats, Glitches, and Spoilers]
------------------------------------
Cheats can be found in the console window. GameFAQs has a section devoted for
these. To open the Console window, simply press the [`~] key during the game.
Type in the cheats as instructed, and voila! Now you can shoot rockets too!
There are a few more ’cheats’ that involve getting stuck in certain rooms. When
you get stuck, the doors will open permanently. This breaks some of the puzzle
elements inside the game. You can get stuck in room 11, 12, 13, and 18 if you
try hard enough. From what I hear, getting stuck in room 12 is permanent. You
will have to reload your game if you manage to get stuck there, so be careful!
- Thanks to CCDemon for this tip!
Glitches? Heck, GLaDOS is a glitch. I wouldn’t say there are any real glitches
that I’ve found in this game. It is truly linear. There are not multiple paths
so far as I have found. If you have any information on this, if you have found
multiple endings, or if you have discovered a way to beat the game without
burning your companion cube, let me know! ;)
As for spoilers... THE CAKE IS A LIE!
Again, Aperture Science and Black Mesa are competitors for DoD funds. GLaDOS
was originally slated to be a de-icing module for Fuel Systems. However, the
kind folks at Aperture Science decided to also turn it into an artificial
intelligence with Genetic Lifeforms at its core... Oh, and as if that wasn’t
enough, they also made it into a Disk Operating System. Because you need to
integrate everything into one system. That couldn’t possibly go wrong.
Well anyhow, if you’re going to have an artificial intelligence run your
corporation, take Marvin’s Advice, and don’t imbue it with cake recipes.
"Here I am, brain the size of a planet, and they ask me to take you to the
bridge. Call that job satisfaction? ’cause I don’t."
Anyway, GLaDOS does give you some more story before she bites the big one.
"You’re not even a full-time employee". Apparently, Chell works here. It is as
I had thought; A Cube Zero scenario. Chell was an employee who became trapped
in the system. I don’t think the system was supposed to be that bad, either.
I think that GLaDOS’s malfunctioning had a LOT to do with how dangerous many of
the trials were.
So, Chell is a female. GLaDOS has a female personality. Do any males work here?
I guess Black Mesa was a corporation that consisted mostly of male scientists
and male security guards. If Aperture Science isn’t run solely by females, it’s
not very apparent by playing Portal’s first incarnation. Also, portals seem a
lot more stable than the teleporters you see in halflife 2.
The "Artificial Intelligence" is pretty well thought out. Actual A.I.s actually
do need a curiosity module, a computing module, and a ’morality’ module is very
much implied, at least since the introduction of Asimov’s three laws of
robotics. An Emotion module isn’t required, and if you do put one in, it’s a
good suggestion to limit it to simply ’coloring the language’, not influencing
the entire behavior of the computer.
So how does Aperture play into the Halflife universe with Black Mesa and all of
that? Well, I guess you’ll just have to play HL2:ep 1 and 2 to find out!

AKA: More Spoilers
If you go to this website, you are presented with a prompt. You can type:
LOGIN
LOGON
USER
at the prompt, and you will be asked for your name and password. There are two
options here. (As of this writing, the website is at version 17. Version 16 had
only one login name).
Your options are as follows;
Username: Any User Name
Password: PORTAL (or PORTALS)
You will taken to a Disk Operating System (Aka: GLaDOS). Only one file will be
present on the disk; "Apply.exe"
Username: CJOHNSON
Password: TIER3
You will taken to GLaDOS. Two files will be present on the disk; "Apply.exe",
and "Notes.exe".
The only differences between accounts is that Notes.exe exists for Cave Johnson
and that "Interrogate" is a valid option for Cave Johnson. (Unfortunately, no
user exists to interrogate.)
Anyhow, typing "Apply" will take you to a fairly amusing test for employment at
Aperture Science. Certain letters during the test will flicker. In order, the
letters that flicker are T, H, E, C, A, K, E, I, S, A, L, I, E.
Typing "THECAKEISALIE" at any time during the prompt will result in a
secret video of level 00, as well as a "Boss Screen" which appears to show a
budget for thumbtacks, a lot of flour (for baking all those cakes?), and one
extra large "Intub". I’m going to assume that this is the "Relaxation Vault".
[Special thanks goes to Jakub Offierski for pointing out the right way to get
to this area.]
Typing "Notes" as Cave Johnson will take you to some back story. Apparently,
"Aperture" was originally a term regarding shower curtains. Who knew! There are
also some amusing projects listed there, like the Take-a-wish foundation. xD
