[I. Introduction]  
 ---------------  
Hey guys! Saul here. This will actually be my first guide I have ever  
written, so I hope you guys enjoy it. I have included links to videos that  
I have recorded throughout this guide if you need some visual aid.   
Contact me anytime via my email, and I will be happy to update my FAQ   
and answer anyones questions. Also, please ask permission before you put  
this guide on another site.  
 
UPDATE: (May 29, 2011)  
I have come to the conclusion that it takes WAY too long to write and  
record video for my FAQs. I may do it in the future, but for now, I can't 
promise I will finish the videos for the other sections of this guide.  
HOWEVER, if you have a video you would like to share, send me a link to 
swiggy12@gmail.com. I will give you full credit! Thanks guys.

~~~~~ CHAPTER 1: The Courtesy Call [C1] ~~~~~  
  
  
  
[0.0] - Tutorial  
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
When you begin the game, you will wake up in what appears to be a hotel room.   
To ensure you are physically fit, a male voice will ask you to look up and   
down. Whew, what a workout! Next, go stare at the picture of the mountain   
on the wall when asked. When you have done all, go back to bed. Easy stuff.   
  
After you wake up, you will hear someone speak. Walk over to the door in your   
little  hallway and open it to find Wheatley, your new robot friend! The   
voice over the intercom will alarm you that itís time to evacuate. Wheatley   
will then enter a hole in the ceiling, but rest assured, he will get you out   
of here!   
  
When Wheatley asks you to say yes, press A. You will jump. He then asks you   
to say apple. Press A again, and you jump again. Wheatley will then go back   
up to the roof and start moving the room around.   
  
Jump into the debris of your chamber. Wheatley will leave you shortly after   
this for the time being. Head forward and fall through the glass and into   
a room. This activates the male announcerís voice. Let the tests begin!   
  
  
  
[1.1] - Test Chamber 00       
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
Well, doesn't this look all too familiar! You should notice that this   
first chamber looks similar to the first room in Portal 1. There will be an   
orange portal that appears on the wall. Stepping through it will make   
you come out the blue portal outside of this glass chamber. Go through the   
first hallway. Stepping the big red button on the floor will release a   
cube. Go over, pick it up with X, and carry it back to the big red button   
and press X again to release the cube on top of it. The door will open.   
Go through it.   
  
  
  
[1.2] - Test Chamber 01       
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
Dropping down into this chamber, you will notice there are three glass   
rooms. Pressing the red button in front of these rooms will open up blue   
portals. First, press the red button on the right, then head through the   
orange portal (located right behind you when you first drop into the   
chamber). Pick up the cube, then turn back.   
  
Go hit the red button on the left of the room, then go through the orange   
portal again. Drop the cube on top of the big red button. Head back.   
  
The door on the north end of the room is now open. Hit the red button   
in front of it, and go back in the orange portal. Continue through the door   
and onto your next test.   
  
  
  
[1.3] - Test Chamber 02       
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
Going into this test, you will reunite with Wheatley. Hurray! Go towards   
the middle of the room where the portal gun is suppose to be. Instead, the   
floor will give way, making you fall down with it. Make your way to the   
room with crazy drawings on the walls. Go up the stairs and you will   
find your precious portal gun. Finally!   
  
Using your new toy, shoot a portal at the wall. It will make you come   
out of the orange portal up top. Climb up the stairs and simply walk   
through the various hallways. Eventually, you will drop down, and an   
orange portal will appear. Shoot a portal at the wall to come out the   
orange side.   
  
You will come to an area that seems like a dead end, but fear not! Simply   
shoot a portal near the door in which you are trying to get to, and   
go through the orange portal behind you. Go through the door and   
onto your next test.   
  
  
  
[1.4] - Test Chamber 03  
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
This next room will have smooth jazz to sooth your soul. Neat! You   
will notice a cube falling down into a deep pit on the right side   
of the room. When it falls down, shoot a blue portal underneath   
it, making the cube come out of the orange portal on your level.   
Simply take the cube and put it on the big red button.   
Continue through the door to your next test.   
  
  
  
[1.5] - Test Chamber 04  
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
When you enter this room, you will notice an orange portal appear up top.   
Shoot a blue portal at a nearby wall to get up there. Next, shoot a portal   
at the wall directly across from you (the platform with the cube).   
Turn around, go through the orange portal, and grab the cube on the   
other side. Drop down and put that cube on one of the big red buttons on   
the floor.  
  
On the north side of the room, there is a small pit with a cube in it. Shoot   
the floor underneath the cube to make it come out of the orange portal. Get   
back up there, grab the cube, and put it on the other big red button.   
Head through the door. You will be in a closed-off room, so just shoot   
a portal on the wall to get out. Head to the elevator.   
  
  
  
[1.6] - Test Chamber 05  
(Video - http://www.youtube.com/watch?v=fsFDgu0VgfQ)  
----------------------  
Entering this room, shoot a blue portal on the floor to come out of the   
orange one. Now press the standing red button to dispense a cube on the   
north-east corner of the room (follow the blue dots on the wall to find it).   
Shoot a portal underneath the newly-dispensed cube to make it come out of the   
orange portal behind you. Pick it up and put it on the big red button.   
There are some stairs that will form after you do this, so go up them.   
  
Go towards the two standing red buttons. The left one will release another   
cube, and the right one will bring up the wall. What you must do is shoot   
a portal where the cube falls, sending it out of the orange one. However, a   
couple seconds after releasing the cube, go over and hit the button on the   
right. This will bring up a wall that keeps the cube from flying into the   
water. Go down and pick up the cube. Climb back up the stairs and place   
it on the big red button on the floor. Head through the door.   
  
  
  
[1.7] - Test Chamber 06  
(Video - http://www.youtube.com/watch?v=UlpTzRoEP00)  
----------------------  
Shoot a portal on the wall to get into the next room. Now you will want to   
shoot a blue portal in the bottom of the pit in the middle of the room.   
Next, jump down into the portal. The momentum will send you flying onto   
the other side of the room. While on this platform, there is a small   
glass room with a hole in it below you (near the edge of the platform).   
Looking through the hole, shoot a portal underneath the cube in this   
small room. This will send the cube through the orange portal. Go back   
and pick up the cube.   
  
Shoot another blue portal in the pit, and then   
jump through it while still holding the cube. Put the cube on the big   
red button, and go through the door. When you enter the next room, look   
to the left. Shoot a portal on the slanted panel, and then jump down into   
the pit and through the orange portal. Next, grab the cube, shoot a portal   
on the opposite side of where you shot your first portal, and jump down into   
the orange portal again (while still holding the cube). Go put the cube on   
the big red button on that platform.   
  
Now, shoot a portal way up high on the same wall that you did last time.   
Jump through the orange portal, and walk through the door.  
  
  
  
[1.8] - Test Chamber 07  
(Video - http://www.youtube.com/watch?v=RhXI4o8T1UM) 
---------------------- 
You'll meet back up with your witty robot friend, Wheatley. Hurray! Place   
a portal on the wall behind him and jump through the orange one. He'll   
detach himself from the rail, so pick him up with X and plug him into   
the socket that comes out of the wall. After he opens up a secret wall,   
Pick him back up, get on the catwalks, and follow them to the next area.   
You will eventually reach a broken-down GLaDOS. Go past the big metal   
circular object and you will find some stairs. Following that, you will   
reach the breaker room/cylinder. Plug Wheatley in when you get the   
chance. After he accidentally wakes up GLaDOS and you fall into the pit,   
move along the rails and wreckage until you come across the complete portal   
gun. Fire a portal on the wall ahead and then fire one on the wall next to   
you to continue on. The rest of this chapter just consists of firing portals   
to get past obstacles. End of Chapter 1!   
  
  
  
~~~~~ CHAPTER 2: The Cold Boot [C2] ~~~~~  
  
  
  
[2.1] - Test Chamber 01  
(Video - http://www.youtube.com/watch?v=oPfdwgYi1xo) 
----------------------  
In this room, GLaDOS says she is going to trap you in a room with deadly   
lasers! Oh no! Well, luckily, there is only one laser. You will want to   
shoot a blue portal where the laser is hitting on the ground. Go stand   
on the lift near the door. Now, shoot an orange portal above the laser   
receiver (follow the illuminating dots on the left wall to find it).   
  
The lift will rise, and you can go ahead and continue unto your  
next chamber.  
  
  
  
[2.2] - Test Chamber 02  
(Video - http://www.youtube.com/watch?v=oPfdwgYi1xo) 
----------------------  
First, jump over the laser in this room. Find the small area in this  
chamber's corner that has a cube in it. Shoot a blue portal under the cube,  
and then shoot an orange portal on a nearby wall to grab it.   
  
Position this cube in front of the laser beam (while still holding it), and   
then try to deflect the laser into the receiver nearby (again, follow the   
glowing dots on the wall). Walk up the newly-formed stairs.  
  
You still need a cube to put on the red button. While still being on the   
second floor, shoot a portal underneath the cube you just used. Fire another  
portal on the floor, grab the cube and put it on the red button. 
 
Continue through the door.   
  
  
  
  
[2.3] - Test Chamber 03  
(Video - http://www.youtube.com/watch?v=oPfdwgYi1xo) 
----------------------  
When you enter this room, get up to the platform with the cube on it (not   
the platform in the middle that raises) by using portals. Look up. See that  
laser receiver? Go ahead and shoot an orange portal on the floor   
directly below it. Grab the cube and jump to the middle platform.  
  
There are two laser receivers in this room--one on the wall, and one on the   
ceiling of the platform you just jumped from. Using the cube, deflect a  
laser into the receiver on the wall. Next, shoot a blue portal on the   
wall that the other laser is running into. Both lasers should now be hitting  
their receivers, allowing you to go to your next chamber.   
  
  
  
[2.4] - Test Chamber 04  
(Video - http://www.youtube.com/watch?v=ERuu6_uo7Nk) 
----------------------  
Look to the left when you enter this room. Place an orange portal on the   
middle part of the wall, and a blue one on the platform with the red button   
across from you. Hit the red button so a cube appears. Now shoot a blue   
portal on the wall that the laser is hitting into, making it come out of   
the orange portal and hitting the receiver. The platform will now start to   
move. Jump on it with the cube in hand, and ride it until you hit the other   
side. Place the cube on the big red button and carry on through the door.  
  
  
  
[2.5 - Test Chamber 05  
(Video - http://www.youtube.com/watch?v=ERuu6_uo7Nk) 
----------------------  
This is probably one of simplest (and enjoyable) challenges yet. The launch   
pads are bouncing a cube back and forth, so all you have to do is jump on one   
yourself and catch the cube. Try to launch yourself when the cube is near 
its highest point. When you have grabbed it, put it on the big red button.   
Carry on to your next test.  
  
  
  
[2.6] - Test Chamber 06  
(Video - http://www.youtube.com/watch?v=ERuu6_uo7Nk) 
----------------------  
Jump on the launch pad in this room. You will bounce around a couple times,   
and then head towards a wall with two slanted panels. The idea here is to use   
momentum to shoot out one slanted panel and through the next, launching you   
to the other side. You have to try and act fast because you only have a   
limited amount of time. But if you screw up, no worries--just portal yourself   
to the start and try again.  
  
Once you are on the other side, hit the standing red button for a cube. After   
GLaDOS is done being a funny gal by sending you junk to use, she will send   
you a cube. Catch that when it is coming near you. Shoot a portal atop of the   
big red button nearby, and the other on a wall. Try to drop the cube through   
the portal and onto the big red button. Once you have accomplished that, head   
through the door.  
  
  
  
[2.7] - Test Chamber 07  
(Video - http://www.youtube.com/watch?v=ERuu6_uo7Nk) 
----------------------  
Grab the cube with the heart symbol on it. After GLaDOS dissolves it a few   
times (damn her trickery!), she will give you a proper one. Block the lasers   
path via the cube, and jump on the elevator. You will want to now move the   
cube to go up, so move the cube with portals.   
  
Now that you are up top, get the cube up there by using portals. Stand   
between the two slanted panels and look across the room. Grab the cube, turn   
left and shoot a portal on that panel. Using momentum, jump down through the   
other portal, sending you to the other side. Put the cube on the big red   
button. Move the portal on the panel to the panel beside it, and using the   
previous principles, use momentum to get to the other side. Go through the   
door.  
  
  
  
[2.8] - Test Chamber 08  
(Video - http://www.youtube.com/watch?v=lhoD3-OJTh0) 
----------------------  
When GLaDOS is done talking, head up the stairs and through the translucent   
wall. Hit the standing red button to call down a cube. It will dissolve if
you try and bring it through the wall, so you will have to use your portal 
gun. Shoot a portal through the glass portion of the wall with a hole in it, 
and another behind you. Bring the cube through the portal.   
Using the cube, aim the laser to hit the receiver outside of the wall. Head   
through the door. Congratulations on completing Chapter 2!   
 
 
 
~~~~~ CHAPTER 3: The Return [C3] ~~~~~  
 
 
 
[3.1] - Test Chamber 09  
(Video - http://www.youtube.com/watch?v=i6Xa56-5qOE) 
----------------------  
There is a story bit at the first of this room. When GLaDOS finally lowers 
the ceiling, shoot a portal up there--one right above the launch pad, and  
the other slightly further north. Hop on the launch pad and jump through the 
portals. There are three slanted panels in this room. Shoot a portal on  
the slanted panel furthest from the rooms exit. Go back to the launch pad. 
Shoot the opposite portal above it. Using momentum, you should go flying  
up to the second floor. Press the red button, and a cube will drop directly  
across from you. Shoot a portal on the other nearby panel, and using the  
previous step, shoot across to the other side and grab the cube. 
 
Using the cube, jump down and direct the laser beam towards the lone wall 
that blocks the laser receiver. Shoot a portal on the slanted panel near 
that wall, and go back to use the launch pad to go through it. Now that 
you are up there, shoot two portals on the lone wall below--one on each  
side of it. The laser should go through the portals as if the wall wasn't 
there, and hit the laser receiver.  
 
 
 
[3.2] - Test Chamber 10 
(Video - http://www.youtube.com/watch?v=i6Xa56-5qOE) 
----------------------  
This will probably be the first test that will leave you scratching your  
head. When you first enter this room, look to the right--you will see a  
cube. How do you get over there? Momentum, of course! Turn around, and  
shoot a portal as high as you can above the entrance door. Go towards  
the platform with the cube. You will notice there is a skinny pit before 
it, and this is where you will use your momentum. Shoot a portal down  
there, and jump through. You should now be on the platform with the cube. 
Grab it, and go back to the entrance. 
 
With the cube in hand, jump on the launch pad. You will hit a glass wall.  
Go towards the laser receiver and put your cube down infront of it. With  
the glass wall lowered, go jump on the launch pad again, which will now  
launch you unto a higher floor. 
 
Hit the standing red button up here. It will shoot a cube up towards you.  
When it reaches you, grab it. Take it down a floor, swap it with the cube 
in front of the receiver, and direct the laser beam to hit the portable  
wall in the distance. Grab the cube that isn't doing anything and hop on 
the launch pad again. Now shoot a portal on the wall across from the laser 
receiver. Pick the cube back up, jump down to the launch pad, and ride it 
one last time. The glass walls shouldn't be up anymore, which will send 
you to the highest floor. Place the cube on the big red button, 
and head through the door.  
 
 
 
 
[3.3] - Test Chamber 11 
(Video - http://www.youtube.com/watch?v=OqDfBAYAywQ) 
----------------------  
This is the first room that will make you utilize light bridges! First,  
shoot a portal on the wall the bridge is running into. Next, shoot the 
opposite portal across the way near the exit. Once you are over there, 
hit the standing red button. You can see through the glass that the  
poor cubes are just falling in the water! This will not stand! 
 
Alright, so now you have to get over to where the cubes are dropping. 
Walk back onto the bridge, and at about the half way mark turn right 
and shoot a portal slightly lower than the height you are at. Now the 
light bridge is running the opposite way. Turn around and walk in the 
direction towards the falling cubes. Turn left, shoot a portal, and go  
forward. Turn right and shoot a portal on that wall--now the bridge  
should be running under where the cubes are dropping, allowing you to 
grab one. With a cube in hand, head through the portal you just made, 
making you come out near the entrance. 
 
Shoot a portal on the same wall the bridge is running into, but higher 
up. Grab your cube, and go through. Without going too far, turn left 
and shoot on the portal close by while standing on your cube (you need 
to keep your cube with you). Go half way on the bridge and look to the 
left--see that glass room with the big red button? Yeah, you need to 
get over there. Turn right and shoot a portal while standing on your 
cube. Walk across the bridge with the cube and put it on the big red 
button. 
 
Alright, home stretch! Simply use portals to get to the exit door. 
You can now head on through it.  
 
 
 
[3.4] - Test Chamber 12 
(Video - http://www.youtube.com/watch?v=Lp07VEfHLoU) 
----------------------  
When you enter this room, shoot a portal above the light bridge up 
and to the left. Then shoot the opposite portal on the nearby wall. 
Now that you are on the bridge, shoot one portal on the wall the  
bridge is running into to, and the other in the distance to the right. 
Go through the portal, which should bring you to the start. Hit the 
standing red button, and make sure your bridge is under the location 
where the cube is falling. Grab one.  
 
Now you need to get to the other side! Get back up to where the 
original light bridge is again. Go to the source of the light bridge, 
and look down. Place another portal on the vertical part of the  
standing red button platform. Ride it to the other side, which should 
lead you to the exit. Place your cube on the big red button.  
 
 
 
[3.5] - Test Chamber 13 
(Video - http://www.youtube.com/watch?v=fQhT1KRSq1s) 
----------------------  
In this chamber, you will be introduced to those pesky turrets. To  
destroy these buggers, simply pick them up and throw them down with X. 
Get rid of the first one this way. Don't run around this first corner  
or you will be pelted with bullets. Instead, shoot a portal behind the 
turret around the corner, and another on a nearby wall. This allows  
you to get behind him without harming yourself. Destroy it. There is 
another corner after this. Shoot a portal underneath the turret, and 
another one on the wall. This should destroy the turret. Continue ahead  
and up the stairs.  
 
To get rid of the two turrets in the glass room, you need to shoot a  
portal on the ceiling, but behind the turret. Repeat this step again  
for the other one. Now they both should be down. 
 
In the next room, there should be three turrets. Using the previous step, 
shoot a portal on the ceiling to drop down behind them. If you are fast  
enough, you can just run to all three and destroy them without getting 
hurt. Simply go back and pick up a cube near the glass room, and bring  
it near the exit door. Place it on the big red button. 
 
 
 
[3.6] - Test Chamber 14 
(Video - http://www.youtube.com/watch?v=YpHmOrOEGPI) 
----------------------  
Once you get lifted up to the next platform, the tests will begin. Pick  
up the cube in this room and take it to the right side of the room  
(while still being lined up with the laser beam). Line up the two 
receivers on the left and direct the laser beam through both of them. 
Now there is just one left! 
 
Shoot a portal on the wall that the laser is now running into. Now 
shoot the opposite portal on the right wall. The laser coming out 
of the portal must hit the remaining receiver. Once you have done 
that, you are granted access to the next chamber.  
 
 
 
[3.7] - Test Chamber 15 
(Video - http://www.youtube.com/watch?v=C62vFmpXShI) 
----------------------  
You will again have to utilize light bridges in this chamber. Shoot a 
portal on the wall where the light bridge is running into. Creep around  
the corner slowly and put the opposite portal on the wall in front of the 
turret, granting you a barrier. Get as close to the turret as possible,  
shoot a portal off to get rid of the barrier and run to destroy the turret. 
Continue on to the wide-open room. 
 
To walk around this room without getting lit up, you will have to use the  
light bridge as a barrier wherever you go. While protecting yourself this  
way, head towards the exit. You will see two launch pads. They will just  
send you back and forth unless you have a light bridge in the middle of  
them, so create one above the exit door. You need to run across the glass 
bridge, but they will pelt you if you don't protect yourself. Shoot a light  
bridge going across the lower part of the room. Now run across the glass  
bridge and fall down. Quickly take out the four turrets there. Grab the  
cube and put it on the big red button in the middle of the room. 
 
Just one small part left! To destroy the two remaining turrets, simply use  
the strategy that I introduced in the first part of this room. Head through  
the door.  
 
 
 
[3.8] - Test Chamber 16 
(Video - http://www.youtube.com/watch?v=xkjsyR2eY6o) 
----------------------  
Get into the middle of this room and stand on the big red button. See that  
laser beam shooting down towards the floor? Shoot a portal underneath that.  
Then, shoot a portal on the wall that faces those damn turrets. The laser  
should come out of the portal, destroying the turrets. Go ahead some, grab a  
cube (not the reflecting one, the standard cube), and bring it back to the 
big red button. Set it on top of it.  
 
Go back and put up the reflecting cube. Point it towards the turrets past the 
glass wall, destroy them, and then point it towards the receiver over there. 
Now you can head towards the exit and through the door.  
 
 
 
[3.9] - Test Chamber 17 
(Video - http://www.youtube.com/watch?v=O9t8wA_U_L0_) 
----------------------  
Yay, more light bridges! Shoot a portal on the wall that the light bridge is 
running into, and another on a nearby wall to get up there. Before you grab 
the cube, shoot a portal on the opposite wall of where your light bridge 
portal is. Grab the cube and head through the portal to the other side. You
should be close to the laser receiver this time. Place the cube near the 
front of the receiver, blocking the beam. It should also be directly over the
big red button. Head towards the elevator. 
 
While standing on the elevator, get rid of the bridge going across the big red  
button. The cube will fall, which should land on top of the big red button and  
lifting the elevator in the process. Congratulations, you just completed  
Chapter 3!  
 
 
 
~~~~~ CHAPTER 4: The Surprise [C4] ~~~~~  
 
 
 
[4.1] - Test Chamber 18 
(Video - http://www.youtube.com/watch?v=IanUwyNjVic) 
----------------------  
This room is a bit unusual. Not only is it very open, but there is a lot of  
things going on. First, Shoot a portal on the other side of the room while 
using the vertical light bridge for cover. Go through the portal. 
 
You should see a standing red button to your left. If you press it, you'll  
notice that the two cubes just bounce into each other and then fall into the  
water. Using the light bridge, make a barrier between them near the far launch 
pad. If you get do it right, both cubes should be on the far away launch pad. 
Return to the start of the room using portals. 
 
BE CAREFUL! If you haven't noticed yet, there is a turret in this room that  
will rip you to shreds. You may need to use cover by constantly using the  
light bridge as a barrier (shoot one portal above the light bridge, and the 
other portal wherever you are on the floor). Go grab a cube, and carefully  
move to the south-west area of the room. See the laser shooting down? 
Direct the laser into the two receivers that are lined up perfectly. Go back 
and grab the other cube. Using the cube, direct the laser in the middle  
of the room to the turret, destroying the thing once and for all! Then,  
simply shoot the laser through the two remaining receivers.  
 
 
 
[4.2] - Test Chamber 19 
(Video - http://www.youtube.com/watch?v=zxeQ9ErGNMU) 
----------------------  
This chamber is hard if you don't know what you are doing. First, grab the  
cube in the middle of the room and bring it to the right side of the room.  
Look up and shoot a portal to the upper platform. Get up there using portals, 
while bringing the cube with you. Direct the laser to the receiver across from 
you. Go back to the middle of the room. Look up where you dropped down near the 
first. Then, look slightly left of that--you will see a small portable tile  
on the ceiling. Portal your way up there and grab the cube when you fall down. 
Bring it up to the entrance door.  
 
Next, you need to get the third cube. Shoot a portal above the launch pad in 
the middle of the room and hop on there using another portal. While you are 
going up and down on this launch pad, look around the room--see the cube up 
high near the entrance? You will need to use momentum to get there. Shoot  
your other portal on the big portable wall on the side of the room. Once you 
get to this final cube, bring it back to the entrance door like you did with  
the second one.  
 
Now we need to get to the location where the first receiver we saw was. Using 
momentum and portals on the wall, shoot a cube over there first. Then, Go 
over there yourself and direct the laser towards the receiver near the  
entrance door. Go back up near the entrance door. Now use the final remaining 
cube to direct the laser towards the turrets across from you, and then towards 
the final receiver near the exit door. A bridge will form. Use momentum and  
portals on walls to get over there. Go through the door.  
 
 
 
[4.3] - Test Chamber 20 
(Video - http://www.youtube.com/watch?v=9Z8Z2pkcbX0) 
----------------------  
Explore this room for a minute. You will find three laser receivers near the  
exit door. Put a portal on the lone wall in front of them. Now look at the  
wall on the right of the entrance door. Place the other portal on that wall 
where the laser is running into. Now one of the lasers should already be  
hitting a receiver.  
 
You will notice that there are two cubes in this room. Take one of them and 
direct the one of the other laser beams into the nearby portal. Position it  
so you can see that you are hitting a receiver. Repeat that step again, and 
you should be hitting all three receivers! 
 
 
 
[4.4] - Test Chamber 21 
(Video - http://www.youtube.com/watch?v=qY_dDT-lOoM) 
----------------------  
Shoot a portal on the wall the light bridge is running into, and another on 
the wall right by the standing red button in the distance (use zoom if you 
need to find it). Press the button and a cube will fall behind you. Go grab 
it...well, try to. The power will go out, and your friend Wheatley will  
return once more. After your chat, start running! 
 
Wheatley will encourage you to keep running, and I suggest you do just that. 
Continue running through the linear path until you get to the room with  
turrets. Find your way around these little guys and destroy them. Near the 
turret that was furthest away is a low wall that you can see over. There 
is a wall outside that you can shoot to portal yourself out of there. 
The rest of the chamber will simply consist of more running until you get 
to the elevator.  
 
 
 
~~~~~ CHAPTER 5: The Escape [C5] ~~~~~  
 
 
[5.1] - Manufacturing Area 
(Video - Coming soon!) 
---------------------- 
The first door will not open, so shoot one portal through the door and the 
other next to you. After walking on a bunch of catwalks you will drop  
down on a moving conveyor belt. Watch out for lasers near the end of this 
section. Next, portal your way up to the next area. Once you are there,  
Wheatley will shine his light on a wall across the way that you can portal  
over to. Do this again and you're back on solid ground. 
 
Well...not for long. The next catwalk is broken, so jump  
down to crate, then down to the next one, and onto the tube. Work your way  
down to the next area. 
 
 
 
[5.2] - Factory 
(Video - Coming soon!) 
---------------------- 
Place a portal somewhere in the office and another one on the wall above the  
first conveyor belt. Move along up to the second conveyor belt. At the end  
of the conveyor belt, drop down onto the catwalk below. 
 
You will then reach a room in which there are some turrets unloading bullets  
on a wooden dummy. Shoot a portal on the wall and the other above the dummy.  
When the turret runs out of bullets, quickly shoot a portal through the far 
window and another on the wall behind the dummy. Continue through the portal. 
 
Keep going until you see a turret assembly line on the left and an incinerator 
on the right. Once in a while, if the turret is bad, it will be flung through 
the air into the incinerator. Wait and catch one of these bad boys in mid-air, 
because you will need it in a minute. When you find the next room, wait 
for Wheatley to destroy the glass. After that happens,  portal inside the 
little room and remove the template turret. Replace the template turret with  
the busted one you caught a minute ago. Follow the linear path after that to 
the end.  
 
 
 
[5.3] - Neurotoxin Generator 
(Video - Coming soon!) 
---------------------- 
Keep waking on the catwalks until you reach the elevator. Once you ride that 
up, press the red button to open the nearby door. Before going in, look up. 
See where that laser is running into the wall? Shoot a portal there. Continue 
through the door. I suggest you listen to Wheatley ramble on in the next room-- 
not because it's important, but it is damn funny. :) 
 
Okay, now go past the room Wheatley is in. Look out and to the left. You will  
see walls slowly rising up in the distance. Shoot your other portal on one of  
the walls. It will destroy the first set of tubes. Now look up and to the  
right of that location. You will see walls moving across the ceiling. Shoot 
a portal on one of these to destroy the rest of the tubes. After this, go  
into the room where Wheatley is, and get sucked into the next area. 
 
 
 
 
[5.4] - GLaDOS' Chamber 
(Video - Coming soon!) 
---------------------- 
Just continue to go through the tubes with Wheatley. Once you reach a part 
where you can go left on a ledge, look up. Shoot a portal up on the ceiling, 
and the other on a nearby wall. Portal yourself over there.  
 
Open the door. It's a fake! GLaDOS has tricked you good! Fall down on the  
moving lift with the toilet. I won't spoil anything here, so just wait until  
you can get out of your glass room and then pick up Wheatley. When the time 
comes, plug him into the computer under GLaDOS. 
 
Head up the stairs. You need to get to that standing red button, but GLaDOS  
will try to prevent you from getting there. You will have to portal yourself 
over there using the wall and the floor underneath your feet. Use the walls 
to get around this next part--when the floor raise and blocks you, run  
through a portal to the other side of the room. Hit the button! Watch the  
craziness that ensues, and fall down to the next chapter.  
 
 
 
~~~~~ CHAPTER 6: The Fall [C6] ~~~~~  
 
 
[6.1] - Area 01  
(Video - Coming soon!) 
---------------------- 
You will reach this area after falling through the wooden planks with the 
"potato". Walk through all the wreckage until you reach a dead end with  
a chain fence. Shoot a portal on the wall across from the fence, and  
another on a nearby wall. Portal yourself over there. Now look up and  
shoot a portal on the portable wall, then portal yourself up there.  
 
 
Walk through the dark alley until you reach another dead end. Shoot 
a portal up and left of the fence (you may need to zoom to find it). 
Get over there using portals. Fall down and walk along the metal  
debris. Take a left. You will see signs like "DO NOT ENTER". Look way 
up and left (again, use your zoom). Shoot a portal up there, and another 
on a nearby wall. Once up there, go down the first set of stairs. Look 
down past the "KEEP OUT" sign. Shoot a portal on the wall down there. 
Go through another portal to get down there.  
 
Fall down and continue walking past the "KEEP OUT" signs. follow the 
path until you reach the levers. Press it. After this, portal over to 
one of the rooms with the numbers above it. You need to press both  
buttons in these rooms within 4 seconds of each other, so use portals  
to do that. Once accomplished, a door will open. You can now go into  
the vault and into the next area. 
 
 
 
[6.2] - Area 02  
(Video - Coming soon!) 
---------------------- 
Go through the door. Walk along the catwalk and go up the stairs. You 
will see a door that is half open. Shoot a portal inside the room and 
get in there. Hit the lever inside and go through the door. You will 
enter a room with a recording being heard over the loud speakers. You  
will need to get to the room to the right of the entrance door. It's  
momentum time!  
 
Look way up and to the right of the broken elevator. Place a portal  
up there and get up to that area. Follow the steal walkway to the  
left and look back and down. Your aiming to go through the the big O 
in the sign down there, so shoot a portal on the wall that will send 
you through there. Shoot the other portal on the floor below, and use 
momentum to shoot yourself through the O and on to the other side.  
Go through the door. 
 
Keep walking until you reach an elevator. Hop on it and go up. When 
you arrive at the top, get out and look to your left. In the distance 
there is a small area with a slanted roof and a few inoperable doors. 
Shoot a portal on the slanted roof. Now go down a couple of flights  
of stairs until you can look down the elevator shaft. Shoot a portal 
down there and fall through, shooting you to the next area.  
 
Hit the switch in this next room. After that, shoot a portal way 
up on the highest catwalk in the next room. Portal up there. Walk  
outside and down the blue gel pipe. Ride the elevator. 
 
 
 
[6.3] - Area 03  
(Video - Coming soon!) 
---------------------- 
Follow the catwalks to the next room. Now you will experiment with  
repulsion gel! This blue gel makes you jump a bit higher. First, portal 
up to the platform with the big red button. Then, jump across the room 
to the standing red button (the blue gel will make you jump higher the 
higher you fall). Hit the button and go grab the cube. Portal up to the  
big red button again and place the cube on it. Jump across the room and  
through the door. 
 
In this next part, look up and shoot a portal on the one portable wall 
above the speaker. Portal yourself up there by shooting the nearby wall. 
Follow the linear path. 
 
 
[6.4] - Area 04  
(Video - Coming soon!) 
---------------------- 
In this room, you will want to portal yourself on to the moving lift.  
Once you are on there, ride it to the standing red button and press it. 
Grab the cube and portal yourself over to the big red button. Place the  
cube on it. You'll notice that it opens up a small portal wall a little 
bit high up. Portal yourself up there, then use the blue gel on the  
floor to jump across to the next room.  
 
In here, jump in between the walls by using the blue gel. Grab the  
cube and bring it back to the big red button. This will open up a final 
portable wall. Portal up there and jump across the room, just like  
before.  
 
 
 
[6.5] - Area 05 
(Video - Coming soon!) 
---------------------- 
Once you get out of the elevator, fall down and walk across the broken 
catwalk. After this, look up very high and shoot a portal on the only 
portable wall up there. If you need help finding it, look for the  
blue gel pipe--it's above the base of that. Portal yourself up there 
using a nearby wall. Walk around the catwalk and you should see a room 
in a short distance. Shoot a portal on the ground in that room and  
portal over there.  
 
When you enter the next room, hit the standing red button. This will  
make the blue gel begin to drip. Shoot a portal underneath it and  
another one on the wall next to the platform that is slightly above  
you (they kind of resemble stairs, but you need the blue gel to  
jump up there). Repeat this step to get up even higher. Shoot a portal 
on the floor between you and the platform with the slanted panel so 
that blue gel comes out of it. When it comes through, move the portal  
so the blue gel falls on the floor. Now use this gel to jump across.  
Do the very same thing again when you get on this platform to jump 
up higher.  
 
Next, shoot a portal on the slanted panel so blue gel goes flying  
through that. Once that is done, you will want to go through 
the slanted panel using momentum. Once achieved, you should fly through 
the panel, hit the blue gel, and finally get to the exit. Neat!  
 
 
 
[6.6] - Area 06 
(Video - Coming soon!) 
---------------------- 
Head into the next room. Shoot a portal on the floor where the gel is 
dripping, and the other on the floor next to the standing red button 
up high. Move the portal when the gel is in the air so that it splats 
on the floor. Jump up and hit the button--this will stop the water flow 
in the middle of the room, but only for a limited time. Quickly shoot 
a portal on the small wall above you behind the mesh steel. You will need  
the gel to shoot through this portal so that it hits the area where  
the water was hitting, and then jump on the gel, shooting you up to the  
platform above you.  
 
Once you go through the door, shoot portals so that the blue gel comes  
out of the slanted panel. Now that the area is coated with blue gel,  
go up high on the catwalks. Jump through a portal and out the slanted 
wall. You will hit the gel and fly up top.  
 
Before going too far, look back down and make sure there is a portal 
underneath the dripping blue gel. Continue on up the stairs and look  
in the distance. Shoot a portal on the wall high up and to the left. 
Once the opposite wall is coated in gel, shoot a portal beneath you and 
use momentum to hit that gel. Once up here, shoot the wall on the pillar  
you are on. After that, look directly up and shoot a portal up there.  
Go through.  
 
 
 
[6.7] - Area 07 
(Video - Coming soon!) 
---------------------- 
In this room, you will notice a glass chamber with a cube inside. Shoot  
portals so that blue gel drips into this chamber. The cube will jump 
around and break the glass completely. Grab the cube. Wash the cube off 
in the nearby water. After that, go place it on the big red button. 
 
Get up to the lift by using repulsion gel and portals. Once you are on  
the lift, shoot a portal above the cube so that gel hits it, making it  
jump up in the air. The lift will raise.  
 
 
 
[6.8] - Area 08 
(Video - Coming soon!) 
---------------------- 
In this next bit, walk forward until you are slightly past the catwalk. 
Turn around and look to your left--there is a portable wall there. Shoot 
a portal there, then return to the entrance lift. Look to the right on the 
big wall that says "1971" and shoot another portal over there. Get over  
there and go through the door.  
 
In this room, portal yourself up top on the catwalk. Look down and place  
both of your portals on each of the white patches on the floor. What you  
will need to do is jump through the nearest portal, and as you are coming 
out of the second one, shoot a portal on the white panel so that you come  
out of that one next. If you did it right, it will send you up to where  
you need to be. Once you're up top, go inside the office and hit both blue 
and orange gel pressure control levers, then move outside. 
 
 
 
 
[6.9] - Area 09 (Control Room) 
(Video - Coming soon!) 
---------------------- 
This is the last area in Chapter 6. Woohoo! Alright, first, get up to the  
catwalks above you using portals. After that, look to the right where a  
massive pipe is. You need to shoot a portal slightly to the right of that, 
and then another one beneath you. Jump down and the momentum will take you 
through to your next area. 
 
Well well, look who it is! Your old buddy GLaDOS is still alive and kicking 
(despite being a potato...). After your chat, she will join you for a bit.  
After this, the lift will raise. You will need to use momentum again to get 
on to that catwalk. Shoot a portal as high as you can while still being  
aligned with the catwalk, and then fall down into another portal. If 
successful, you have just completed Chapter 6!  
 
 
 
~~~~~ CHAPTER 7: The Reunion [C7] ~~~~~  
 
 
 
[7.1] - Area 01 
(Video - Coming soon!) 
---------------------- 
The first thing you will want to do is coat the runway that leads to the
ramp with orange gel. Portal yourself up to the platform with the small red 
button. Before hitting the button, shoot a portal under the gel dispenser 
and another on the wall behind the runway. Hit the button and this will coat 
the runway. Run on this gel and over the ramp to the next area. 
 
Shoot a portal on the nearby wall. After that, look back to the first area 
and shoot a portal where the small red button is. Go back and hit the button
so that the gel shoots out of the second area's portal. Now this runway is 
coated as well. Run across to the third area. 
 
Using portals, grab the cube in the glass chamber. With it in hand, go back 
to the first area and put the cube on the big red button. This will raise 
the ramp on the runway. Go back to the second area, shoot a portal on the
nearby wall again. Have the other portal come out the first area's runway.
Now you will definitely have enough momentum to get across into the fourth 
and final area.  
 
This in area, you will notice another small red button way up above a white 
floor panel. What you need to do is use one of the runways coated with gel to 
get enough momentum to come through the floor panel to fly up and hit the  
button. Head on through the door. 
 
 
 
[7.2] - Area 02  
(Video - Coming soon!) 
---------------------- 
There are two gel dispensers in this room. First, you want to get some blue 
gel on the end of the runway. Look above the very end of the runway and shoot
a portal on the ceiling. Place another where the blue gel will fall after 
hitting the correct red button. Now coat the runway leading up to that point
in red gel by using the same principles. However, instead of using the panel 
up high, you will need to shoot a portal on the pillar infront of you to coat 
the runway. Run and jump across to middle structure.  
 
Next, go around the pillar and look up. Get up to the higher catwalk by using  
portals. Leave a portal up top, and portal back to the start. Now place your 
other portal on the pillar that you are about to jump and hit into. This will 
make you come out of the portal up atop the pillar, shooting you to the exit. 
 
 
 
 
[7.3] - Area 03 
(Video - Coming soon!) 
---------------------- 
This area has a lot of stuff going on in it! First, coat the runway in the  
distance by placing portals under the red gel dispenser and another on the  
wall behind the runway. Right above that wall is a slanted panel--you will 
want to get blue gel coming out of that one. Portal yourself over there. 
 
Now that you are on the runway, place one portal on the wall and another 
on the slanted panel above it. Run through the wall portal and it will 
send you flying to a suspended platform. Grab the cube on this platform. 
While still on this platform, look around until you see a small area with 
a few white panels and a big red button. Portal yourself over there with  
the cube. Before placing the cube on the big red button, you will want to 
coat the platform that rotates with blue gel (that platform is suspended  
slightly ahead of you). Obviously, use portals and blue gel to achieve this. 
 
Now that this platform is coated, place the cube on the big red button so  
that it rotates. Portal back to the start of the level. Look up past the  
runway you coated earlier and you will see another platform with two white 
portal walls. Shoot the one on the left. What you need to do is run on the 
runway through a wall portal and come out of the portal you just made  
beforehand. This will make you bounce off the blue gel you just put on the 
rotating platform a minute ago and on to the exit. Huzzah!  
 
 
 
 
[7.4] - Area 04 
(Video - Coming soon!) 
---------------------- 
In this next little area, look above you and find a catwalk. Portal yourself 
up there and go through the emancipation grid. Look to your right and portal 
yourself up to the wall that says "Pump Station Gamma". Head through the other 
grid.  
 
In this part, stick to the left side of the room and walk into a small room.  
Hit all three of the gel pressure control levers. You can't get back the way 
you came or you will be crushed, so shoot a portal on the wall and another  
in the newly leaked white gel on the floor near you.  
 
Look on the ceiling above the blue gel. See that white gel up there? Shoot  
a portal on it and portal yourself up there. Now jump into the blue gel below 
which will allow you to jump high enough to reach the other side. Now you 
will find yourself in a room covered with red gel. Quickly run past the
crushing structures.  
 
When you exit this room, look to your right and shoot a portal on the slanted  
panel. Go back to the previous room and shoot a portal on the wall in the  
distance (past the red gel). Run through the gel into the portal which will 
send you through the slanted panel and onto the catwalk above. Walk through 
the messy offices. When there is an option of going left or right, head right 
into the control room and hit the button. Now go through the left door. Head 
to the elevator.  
 
 
 
[7.5] - Area 05 
(Video - Coming soon!) 
---------------------- 
This is the only test that had me stumped for quite a while. First, drop down 
into the area where all the white gel is. Keep this in mind for this test-- 
if you place a portal under the white gel dispenser and another somewhere 
else, the gel will propel ahead of that portal. So shoot a portal under the 
dispenser and another in the white gel itself. Coat the outside of the pit 
somewhere so that you can portal out of there.  
 
Now what you need to do is find the only two giant pillars in this room. Place 
the white gel so that it is coating these two pillars. To coat the inside of  
these pillars, keep placing portals on the pillars themselves once they have  
some white gel on them. Go back and forth between them until you reach the 
very top. Before you portal yourself up to the catwalk above, you will need 
to do one other thing. Find the slanted panel nearby and coat that with gel,
as well as the area behind it. Now portal yourself up to the catwalk.  
 
Now that you are up there, go around the pillar and look down. Place a portal  
on the slanted panel and another in the area behind it. Use momentum to shoot  
out of the slanted panel. 
 
In this part, portal yourself up as high up the elevator shaft as you can.  
Keep doing so until you reach an elevator. Place a portal on the elevator 
floor and another on the a white floor panel below (walk around on the 
catwalk until you find it. Fall down and the momentum should allow you to 
reach a higher platform. Now shoot a portal on a floor panel on this higher
platform, and another down in the elevator again. Jump down through the 
elevator portal, and while in mid air, shoot a portal on a nearby slanted 
wall so that when you fall back down you will shoot out of that portal. 
Walk through the door. 
 
 
 
[7.6] - Area 06 
(Video - Coming soon!) 
---------------------- 
First, place a portal up high on a white pillar. Get up there using portals.  
Now look around you until you see a door surrounded by white walls. Above  
that is a slanted panel, so shoot a portal on that. Fall down and shoot a 
portal on the white floor below. You should now be up on a higher level.  
 
Look for the dripping blue gel. Once you find it, place a portal underneath 
it. Place it so it comes flying out of the slanted panel you just used 
moments ago. Now you will want to fall down and portal out of the slanted
panel again--this time you will hit the blue gel, allowing you to go up even 
higher.  
 
There is a single white patch of floor up here. Shoot a portal there, and 
then fall down a level. Then, use momentum yet again to come out of the
portal you just placed. This may seem useless, but trust me. Once you are 
high in the air, look out and shoot the floor on the next platform. Portal
yourself there however you wish and head through the door.  
 
We have gel pumping in this room! First off, place a portal below the white
gel. Move to the end of the room with the slanted wall piece, look above it 
and you'll see a white patch on the ceiling behind some fencing. Place your 
other portal here and coat the slanted panel. Now you need to create a runway
of orange gel. Place a portal under the orange gel, and another on the 
vertical wall just below the slanted panel. What you need to do now is create
two portals on the vertical wall--one on the wall itself, and the other on 
the slanted piece. Run through the speed gel, through the portals, and on to 
the next ledge. 
 
Up here, you will need to get another patch of blue gel to bounce off of 
following the first bit. Look down and shoot a portal under the white gel and 
place the exit portal on the white floor up here. Now, look up to where the 
newly formed white gel on the ceiling is--place a portal there, and the exit 
portal under the blue gel below. This will cause blue gel to drip from the 
ceiling. Now, go back down to the prior floor, and follow the steps to get up
top again. This time around, you should hit the first patch of blue gel, skip 
to the next, and then over to the next little area. 
 
Go around the pillar and spot the white gel dripping. Shoot a portal there, 
and another up top through the mesh fencing. Portal yourself up there. In 
this part, Go to the room with all the gel pipes and find the slanted panel 
through the mesh fence. You will want white gel coming out of this portal--
it will coat the walls, allowing you to portal yourself up. Find the slanted
wall so you can actually walk upwards without falling back down. Portal 
yourself through the fencing once you get to the top.  
 
Now you are in the pump station! Look up and find the high catwalk. It just
runs between two doors that you can't move through. Portal up to it and 
move yourself to the broken edge. Fire a portal on the white patch of floor 
beneath you. Look a bit to the left to find a control room on the same level
as you with Gel Pump Station written above it. On the wall opposite the
control room there's a white patch, very high up. Place your exit portal 
there. Jump in and you should fly over to the control room. GLaDOS will tell
you to look at the paradox poster, then push the button. Go back down and get
on the lift. You have just completed Chapter 7! 
 
 
 
 
~~~~~ CHAPTER 8: The Itch [C8] ~~~~~  
 
 
 
[8.1] - Test Chamber 01 
(Video - Coming soon!) 
---------------------- 
Follow the catwalks into the glass room. Apparently, Wheatley has failed to  
create cubes with legs. Sad. ;( There is a small hole in the glass room next 
to the file cabinets. Portal yourself through this small hole. Walk along the 
catwalks to the lift. Continue to walk along the catwalks, then fall down and 
enter the door. Place one of these turret-cubes on the big red button and 
watch the events that ensue. After Wheatley is done talking, go through the 
door. 
 
Go up the stairs and on to your first Wheatley test! Obviously, because he is 
a moron, this test is super easy. Just hit the small red button so that the 
cube falls down on the big red button. Simply portal your way over to the
exit. After Wheatley is done talking, you will have to do the same test 
again. After that, go through the real exit this time.  
 
 
 
[8.2] - Test Chamber 01 (Again) 
(Video - Coming soon!) 
---------------------- 
In this chamber, you will be introduced to a new element--transfer beams. 
Jumping into one of these beams will allow you to travel inside of it. Now on 
to the test! 
 
First, jump into the transfer beam so that you go up a level. Hop out, shoot a  
portal on the ceiling that the beam is running into, then shoot the other
portal on the lone tile that is right across the platform with the cube on 
it. This will make the transfer beam shoot out of this portal. Ride the beam 
again, going through your portals and on to the cube's platform. Grab the cube
and drop down. 
 
Portal yourself down to the lower level with the cube in hand. Look up and 
find the big red button on the ceiling of this floor. What you need to do 
is shoot a portal on the floor beneath it, and have the transfer cube come 
out of this portal. It will send the cube to the big red button, and it will 
keep it there. Jump in the beam and ride it to the next floor, then head 
through the exit door. 
 
 
 
[8.3] - Test Chamber 02 
(Video - Coming soon!) 
---------------------- 
The first thing you will do in this room is shoot a portal on the wall to 
your right. After that, jump down into the transfer beam. Shoot your other 
portal on the wall infront of you so that you transfer to the other side. 
As you are riding the beam, you will need to alter your direction. Look at
the wall on the left of you and shoot your initial portal so that the beam 
will start sending you to the right. After this, shoot a portal on the 
checkered floor to send yourself up.  
 
Now you will need to get a cube up with you. Hit the small red button and
use the exact same strategy to get it up there. Finally, place portals so the
beam is hitting the big red button, then throw your cube in there. Head 
through the door. 
 
 
 
 
[8.4] - Test Chamber 03 
(Video - Coming soon!) 
---------------------- 
Wait until Wheatley moves the room close to you, then begin your test! 
First, you will want to get to the other side of the room. Get the transfer
beam to come out of the wall near the exit door via portals, then head on 
over to the other side.  
 
Once over here, shoot a portal on the small white wall on the left side of 
the room. Make it so a transfer beam is coming out of this wall. Hit the small
red button so that the cube falls down into the beam. When it runs into the 
wall, make the transfer beam come out of the wall across from you so that it 
brings the cube right to you. Once you have the cube in your hands, you need 
to get back to the side you was previously on. Make a portal so that the 
transfer beam is coming out of the left wall right beside the target sign. 
Jump to the other side. 
 
Once you are on this side, shoot a portal on the checkered floor below you.
You will want it on the checkered floor panel closest to the ledge. Once you 
have a beam coming up from it, jump in the beam with your cube in hand. Once
at the top, shoot a portal on the nearby wall and slightly below you. If you
line it up right, you will go up the exit platform, and the cube will be 
hitting the big red button all at the same time. If done correctly, you can
head through the door.  
 
 
 
 
[8.5] - Test Chamber 04 
(Video - Coming soon!) 
---------------------- 
The first thing you need to do in this room is get rid of the turret. Use the  
transfer beam to send the turret into the pit behind it. After that, you will  
want to get that cube trapped in the beam over to you. Step on the big red  
button to change the beam to an orange color--this will suck in objects 
instead of blowing it out. Once the cube goes through the first portal, 
change that portal so that the beam is coming towards you. Now jump off the 
big red button. The cube should now come right over to you. Now place the 
cube on the big red button and hop in the beam so that you get over to the 
other side.  
 
Now, get the cube off the big red button by using the transfer beam. Once the 
beam is blue again, shoot the floor so that you can ride it up to the exit
door. 
 
 
 
 
[8.6] - Test Chamber 05 
(Video - Coming soon!) 
---------------------- 
First, get a transfer beam to come up through the island area in the middle 
of the room, and then hop on the launch pad. Once you ride the beam to the
top, look ahead of you and shoot your exit portal on the slanted panel. You 
should have enough momentum to go through the slanted wall panel. Once you
are up there, get the transfer beam to come through the island again. Press 
the small red button, and then use the previous strategy to get the cube over
to you. Place the cube on the big red button and head through the door. 
 
 
 
 
[8.7] - Test Chamber 06 
(Video - Coming soon!) 
---------------------- 
The first thing you need to do in this room is get a light bridge to stop
the cube from going into the emancipation grill. Hit the small red button 
to shoot the cube out. Once it hits the bridge and falls down, go down 
there carefully and get the cube (block the turret fire with a light 
bridge). Once you have the cube, go through the light bridge portal and 
back up. Jump on the launch pad. See that you went too far? Make a light
bridge so that it stops you above the catwalk. Try it again with your cube
in hand. Success! Before you go too far on the catwalk, look down and 
shoot a bridge over the red lasers so you don't get shot up in the next 
little bit. Alright, continue forward and drop down with the cube. Place
the cube on the big red button and then portal back up to the exit door. 
 
 
 
[8.8] - Test Chamber 11 
(Video - Coming soon!) 
---------------------- 
This room seems a bit intimidating, but it isn't so bad if you know what 
you are doing. First, get a transfer beam to come out of the white floor
panel between the launch pad and target panel. Jump in the beam, and when
you hit the ceiling, shoot an exit portal on the slanted panel nearby. 
You should now be thrown over to the platform with a cube. Grab it and 
jump down. 
 
Next, go place the cube infront of the deadly laser beam below. Portal 
yourself back up. Next, place a portal on the slanted panel facing the 
transfer beam, and the other on the slanted panel painted with a bullseye.
Jump on the launch pad, and it should send you to another location with 
another cube. Grab it and jump down. Replace the old cube with this one, 
and point the laser beam at the white wall. Portal up top. Shoot some 
portals so that the laser beam hits the receiver in the room. Once 
you have done that, place the first cube on the white platform between 
the launch pad and bullseye panel.  
 
Now, jump on the glass platform that has lowered in this room. Shoot the
portal that the laser beam is going through away so that the platform 
raises. Next, get rid of that cube entirely by placing a portal on the 
floor below it. Now you will notice that the transfer beam is back in 
action! Shoot a portal on the ceiling of the transfer beam, and the other 
below the first cube you got. This will lower the next platform. Jump on 
that one, get rid of this cube, and ride the platform to the exit.  
 
 
 
[8.9] - Test Chamber 12 
(Video - Coming soon!) 
---------------------- 
This room is also intimidating, just like the last one. Alright, first,
get the laser to hit the bottom receiver on the area across from you. 
This will move the platform all the way to the left. Once it is over there, 
stop the laser and portal yourself to that platform. Get the platform 
moving again, and when it is half way past the deadly laser wall, stop it 
quickly. Now make the laser hit the receiver above the first one so that 
it turns off the deadly laser wall. Walk to the other side of the platform
and get the platform moving again.  
 
Jump down and hit the standing red button. A cube will drop--try to get it
to drop on the moving platform. Once it is on there, let the platform run 
close to the wall and then portal yourself above it, and drop down on the 
platform. Using the same idea as before, get the platform back over to 
where the standing red button is, but DON'T JUMP DOWN! Instead, have the 
laser now shoot out the wall towards you, then make the cube so that the 
laser reflects and hits the receiver above the exit door.  
 
Jump down and portal yourself back to the start. And don't worry, your 
cube will not have to be moved again. Get the laser to hit the cube again 
and it will still hit the receiver. Head through the door.  
 
 
 
[8.10] - Test Chamber 15 
(Video - Coming soon!) 
---------------------- 
The first thing you will need in this test is a cube. Go hit the small 
button and a cube will fall on a platform. Stand on the big red button 
and shoot a portal so that the transfer beam takes the cube off the 
platform, then quickly shoot a portal on the wall across from you so
that the cube doesn't fall into a pit. Once you have this, place the cube 
in the tiny glass room with the big red button. Orange gel is now falling!  
If you haven't figured it out, you need to coat the runway like you have 
previously.  
 
Stand on the big red button and make the beam come out of the wall so that
the orange gel is carried down across the runway. Change the portal and 
make enough orange gel fall to coat the runway. Now take the cube out of 
the glass room and put it on the other red button. Go to the end of the 
runway and look to your right. You will need a transfer beam coming out 
of that white wall (try to get the portal closest to the right as you can).
Once you have a transfer beam coming out of that portal, run and jump into 
the beam. If you did it correctly, it should send you right to the exit 
door!  
 
 
 
[8.11] - Test Chamber 16 
(Video - Coming soon!) 
---------------------- 
Once the floor crashes ahead of you, use the white gel to portal to the 
other side. Now that you are in the actual test chamber, go ahead and 
portal yourself on the distance platform. Get the transfer beam to come
out of the wall above you so that when you hit the small red button for
the blue gel, it will transfer it over to the previous platform. Before 
you take it over to the previous platform though, you need some on the 
platform you are on now, so do that. There is only one small area it can
go on--the rest will go through the mesh. Now, start pumping the blue
gel through the transfer beam, and then jump in it yourself. You will 
want to try and be ahead of the blue gel!  
 
Once you get over to the next side, jump off and quickly hit the big red
button. This will change the direction of the beam. Once it goes through
the first portal, look to your right. See those damn turrets? Well, you 
need the blue gel to destroy these buggers! So once it goes through the 
first portal, hop off the button and shoot a portal on the wall above 
the turrets (but make sure it isn't the portal that is allowing the
transfer beam flow). This should allow the blue gel to start transferring
out above the turrets. When the gel is above them, shoot your portal
elsewhere so that the gel falls on the turrets, which will destroy them. 
 
Now hit the small red button that you can get to now that the turrets are 
gone. There is a slanted panel that forms out of the wall. Make a transfer
beam come out of the floor. When you hit the ceiling, shoot an exit 
portal on the slanted panel. You will skip across to the next area!  
 
[8.12] - Test Chamber 17 
(Video - Coming soon!) 
---------------------- 
Whew, Wheatley tells you there is only two chambers left! So go ahead and
start by jumping on the launch pad and...wait a minute! What the hell! 
Yes, Wheatley tricks you! Wait until you're on the platform to start your 
final chapter... 
 
 
 
 
~~~~~ CHAPTER 9: The Part Where He Kills You [C9] ~~~~~  
 
 
 
[9.1] - Area 01 
(Video - Coming soon!) 
---------------------- 
Think fast! Shoot a portal where the white gel is dripping, and another
on the white spot above so that it shoots out on to the platform. Quickly 
portal over to that spot. Walk along the catwalk until you reach a dead 
end. Look down a shoot a portal down there, then look up and to 
the right and shoot a portal up there. Use momentum to get to the next
area. 
 
Once Wheatley crushes the cube (poor thing!), the catwalk will be useless.
Go back a little and shoot a portal on the nearby white wall, and another
way up high above of the catwalk. Portal yourself out and down, and head
through the door. 
 
 
 
[9.2] - Area 02 
(Video - Coming soon!) 
----------------------  
Once the wall has blocked your path, portal yourself above your current 
location. Once you are in this room, you will be surrounded by turrets!
But don't worry, these guys are harmless. Continue through the door and 
drop down. Once you are in the next room, there will be some turrets that
WILL be harmful. Carefully look in the room with the turrets and shoot a 
portal on the wall with the transfer beam. Then, shoot another portal
behind the turrets so that they are sent out of the room and to their 
doom.  
 
Next, jump in the same beam and let it carry you to the next room. Have
this transfer beam shoot out the door, and then jump in it. Before 
Wheatley has you killed, shoot a portal on the wall infront of you so that
you fall down and ride to the other side. Head through the door. 
 
In this room, wait for the blue gel to fly everywhere, then jump across 
the broken catwalk with it. Shoot a portal on the nearby wall, and another
in the small room directly above you and to the right of the first corner
you turn. Once in here, step on the big red button. What you want to do is
get the blue gel to hit the turrets behind you, so do that by using
portals. After they are taken out, shoot a portal on the slanted wall 
facing the launch pad and get over there. Hop on the launch pad and
continue to the exit door. 
 
 
 
[9.3] - Area 03 
(Video - Coming soon!) 
--------------------- 
First, shoot a portal on the wall above the red button in this room. Then,
shoot a portal through the broken window out to the white floor. Hit the 
button and watch the bombs fall. Make sure you have your portal under
these! It will send the bombs to your room, breaking the white gel piping. 
Now you can portal yourself out of this room. Run around the corner and 
find the next door. 
 
Start walking up the conveyor belt until Wheatley tries to kill you, yet
again. Turn around and jump to the left, avoiding the deadly clomping 
machine. Hit the button found here. You need these bombs to break the 
orange gel pipe, just like in the room before. Once you have done that,
place a portal where the orange gel is pouring out into, and another on 
the wall of the conveyor belt. Now you can run up the belt, through the
portal and on to your next room. In this room, have the orange gel come
out of the narrow hallway. After that is coated, place another portal 
underneath the blue transfer beam. Run through the portal and up into the
beam. Ride it to the next room. 
 
Portal up through the mesh. Get ready, because IT'S FINAL BOSS TIME! 
 
 
[9.4] - Final Boss Fight 
(Video - Coming soon!) 
--------------------- 
Portal yourself way up into the next room. You will walk by some corrupted
cores--this will be Wheatley's downfall! Place GLaDOS into the machinery,
and ride up to your final test.  
 
Wheatley will brag about being smarter then GLaDOS by taking portal 
surfaces away, but he didn't count on some white gel! When he starts 
throwing bombs at you, make him hit the white gel pipe. The white gel will
now pour out everywhere! Success! He will continue to throw bombs at you, so  
what you need to do is make a portal on the floor near you and on the
panels up high. You need to have the bombs go through the floor and then 
through the panels behind him, which will bust him up good. GlaDOS will
now give you your first corrupted core. Portal up to the catwalk and grab
him. After this happens, the blue gel will pour out a bit. Use it to jump 
up to Wheatley and attach the first core on him.  
 
Now he will bring out more shields! Luckily, it still isn't too tough to 
get around. Use the same strategy as before until you hit him with his 
own bomb. Once he is down, GLaDOS will bring you your second core. He is
swinging back and forth on a catwalk. Portal up there, jump into the blue 
gel and grab him at the right moment. Jump up to the right of Wheatley 
to attach the second core. 
 
Alright, only one left! Do the same thing as before to hit him with 
another bomb (yeah, this boss battle is unfortunately kind of weak :/).
Once you have done so, your final core is available. The way you reach 
him this time around is by placing a portal below him, and another on 
the wall to which the orange gel is now next to. Run on the orange gel,
through the portals, and grab the core. Jump up to Wheatley to take him
down once and for all! Or is it... 
 
I'm not going to spoil the next part for you, because it is a great
ending. It's very easy to figure out so just enjoy it! CONGRATULATIONS!
You just beat Portal 2!
