Chapter 8: The Itch
Wheatley Test Chamber 01

So we are back in the newer part of the the Aperture Science Labs. Go through the door and follow the walkway until you are in this small control room above the
test chamber. Wheatley is babbeling something, he probably desperately and most of all unsuccessfully tries
to teach the crippled cubes some tricks. But this is not that interesting for you, so turn away from the huge chamber and shoot a portal through the small
opening in the wall behind you and another portal into the control room to jump through and land on another crate walkway outside of the test chambers. Follow
this walkway until you finally are inside the testchamber. Get one of the broken cubes and put them onto the red switch on the ground. But somehow the exit is
blocked now. After Wheatley and GLaDOS are done with talking about paradoxes Wheatley opens the door for you. Artificial Intelligences talking about paradoxes is
a bit paradox in itself, but nevermind.

Now we enter the first test chamber that our old favourite idiot Wheatley designed all by himself. And it's just as stupidly easy as you could expect. Push the
button and the Weighted Companion Cube will fall out of the cube dispenser and land on the red switch on the ground and this will open the door already.
But you can also refuse to do anything and just wait and listen to Wheatley go crazy...
Portal over to the
switch and exit through the giftshop, no, through the exit.
But Wheatley is not only stupid but also lazy, so he makes you solve this chamber again. Do the same as you did just seconds ago
and then you can exit to an elevator to
more of Wheatley's test chambers.
Test Chamber 01

Again chamber number 01, but this time it's more interesting than the last Chamber 01. The transport beams are introduced in this chamber.
If you jump into these beam you are
transported to the direction the beam moves to.
Jump into the beam right now and travel up one level.
Jump out of the beam once you are upstairs and shoot a portal to the place where the beam hits the ceiling. Shoot another portal to a wall here,
so that the beam aims at the crippled cube in here. Now jump into the transport beam again and this time the transport beam drags
you - through the portal - right to the cube. Get the crippled cube
and jump down to the hole in the ground. Shoot a portal through the hole to a wall down one level. Shoot the other
portal to a wall up here and take the cube with you down
there. Now open one of the portals at the end of the transport beam and put the other portal to the ground right under the red switch on the ceiling.
Throw the crippled cube you have with you into the transport beam
and it will get carried towards and push down the button on the ceiling forever while you can easily escape this chamber through the exit.
Test Chamber 02

Look down into the deep abyss right in front of you. Down there is a lone transport beam. So you have to jump into this transport beam and put a blue portal to the
end of the beam. Now you shoot the orange portal to the only white wall that can hold a portal and that you can see from here.
As soon as you are on the other side of the portal turn left and look for the white portable wall
there. Put the orange portal onto this wall once you are directly in front of it. The transport beam will get you and move you above a small plattform. Shoot the
orange portal onto the platform and you move up to a button to press.
Press the button and the Weighted Companion Cube will fall down. Catch it with the transport beam and have it move towards the small platform and use the transport
beam through the orange portal on the floor of the small platform again to move it up to you. So you are moving the Cube in the same way that you made your own way up here.
Grab the cube out of the beam as it moves by and put it under the red switch in the ceiling. Now all
you have to do is move the cube towards the red switch with another orange portal directly under it so that the transport beam reaches the cube and presses it
against the switch on the ceiling. The bridge to the exit appears and you can escape to the elevator.
Test Chamber 03

And again it's all about the transport beams. So shoot the blue portal to the end of the transport beam and the orange portal to the part of the wall to the
right of the exit. This creates a bridge you can use to reach the push button on the other side of the gap.
But if you push the button now the cube just falls into the endless void of the aperture
science depths. So shoot the orange portal real close to you to the wall on the left and push the button. The cube should fall into the transport beam and
moves to the right. Once the cube reached the wall shoot the orange portal to the white wall
behind the cube so that the cube moves towards you and you can grab the cube. But how do you get back now?
It's quite easy, just shoot the orange portal to the left of the grey wall with the light blue circles on it. Get the cube and walk onto the catapult and while
you are moving nicely along the corner of the abyss just jump back into the huge room you came from.
Here you put the cube onto the checkered area close to the edge and walk towards the exit. Put the orange portal on the ground in front of it and use the transport
beam to get up onto the plattform in front of the exit. Turn around really quick and shoot the orange
portal under the cube while it is still on the checkered area. This has to happen really fast as the cube tries to walk away. Once it moves up above the checkered
area wait until it is under the ceiling and then shoot the orange portal to the single grey plattform right above the cube dispenser in the distance
and then you can watch the defunct
cube move towards the red switch on the wall and see how it opens the exit for you. Wheatley is talking some more bull but you are gone with the elevator already.
Test Chamber 04

So, again shoot the orange portal to the place where the transport beam hits the wall. And place the blue portal where the turret laser hits the wall on the
opposite side of the chamber to have the transport beam move the annoying turret to the abyss in the back of the chamber.
After this is done (and the turret is done) shoot the blue portal to the white wall on the left over the gap to grab
the cube on the other side with the transport beam. As soon as the transport beam got the cube, step on the big red switch on the ground to turn around the direction of the
transport beam. The transport beam also changes color, but the direction is the important part here. So the cube will move towards the portal now, but you shoot
another blue portal on the wall opposing your side of the chamber, but make sure to not hit the exact opposite location or the transport beam will drag you away
from the switch. But you have to get down from the button anyways to make the cube come over to your side. Once the cube is close,
grab it out of the beam and place
it on the red button on the ground. Then jump into the now orange transport beam and let the transport beam move you over to the other side.
Once you are over the gap, get out of the beam and place a blue portal directly opposing the cube on the red switch, so that the cube gets carried away from
the red switch on the ground.
This turns the transport beam blue again and you can place a blue portal on the ground directly in front of the platform where the exit is located
and slowly move up to the exit.
Test Chamber 05

A true classic. Not just because of the music, the solution is really easy once you got it. Actually you just have to have the transport beam going up from the
lonely platform in the middle of the room and then use the catapult to jump into the transport beam. Once you're caught by the beam and the transport beam took
you to the top of the chamber you just shoot another portal
to the slanted platforms opposing the exit. You will now fall down into the portal below you and just jump to the exit.
And once you are there you do the same for the weighted companion cube that will
come out of the cube dispenser once you pressed the button near the exit. Once the cube landed next to you, you just put it onto the big red switch on the ground and the exit opens
up for you and you can use the elevator to reach another test chamber.
Test Chamber 06

Well, well, it's just getting complicated, but not difficult. Just press the button to see what happens and what path the weighted companion cube flies. Sadly
the companion cube dies when it passes through the blue energy field. Well then, shoot the blue portal to the end of the light bridge and the orange portal
high on the wall opposite the button to be there as a barrier and stop the weighted companion cube in flight. Once the cube landed in front of the hidden turrets
and didn't burn to dust shoot an orange portal on the wall down there as a barrier between you and the turrets and then jump in the pit and get the cube. Carry
the weighted companion cube around one of these corners, so that the turrets can't hit you, shoot one portal high on the wall where you already had a portal
to stop the cube in flight and the other portal to the wall right next to you and you can easily escape with the cube.
Now you shoot a portal to the end of the lightbridge again and the other one to the single white platform on the wall to the right of the image of Wheatley. Use
the catapult to shoot yourself and the cube against the lightbridge and you will stop on a metal walkway. Walk along the walkway a bit, then shoot a portal in
front of the turrets to guard you with a lightbridge and after that it's finally time to use the metal walkway to walk behind the blue energy field,
jump down and put the cube onto the big
red switch on the ground. And voila, the exit opens and you can even portal yourself up to the exit from behind the blue energy field. Take the elevator to get to
yet another test chamber.
Test Chamber 11

Nobody knows why, but the next chamber is chamber 11. Wheatley tries everything to confuse you, but fear not, the solution is right here. Mabye he
wants you to finish faster so he is done with you faster...
At first we want to get the crippled cube. Shoot a blue portal to the end of the transport beam and an orange portal directly onto the single plattform on the
ground right in the middle of the room right there when entering the room. Jump into the beam and once you are high up with the transport beam shoot the blue
portal onto the slanted plattform with the lightblue circles on it right next to you and the beam. You get thrown right to the broken cube.
Pick up the broken cube and jump down into the ditch to the laserbeam and put the broken cube into the laserbeam. The transport beam will stop working. Now
portal up out of the ditch and put a portal onto the slanted platform above the laser emitting pod we just blocked with the crippled cube and the other portal onto
the slanted wall we already used right next to the entrance to this room. Now use the catapult right next to the entrance and after the catapult threw you
all across the chamber you will find yourself next to a mirror cube, and this is just what you need right now.
Of course you take the mirror cube with you. Put it into the laser beam so that the beam is reflected straight into the wall down there. Take the broken cube from
down there with you and leave the ditch through some portals. Put the broken cube right onto the single plattform on the ground in the middle of the room and leave
it for a while.
To the left of the slanted wall with the lightblue circles on it is another laser pod that just waits for the laser to come in, so put a portal on the short
wall opposing the laserpod and another portal down in the ditch right where the reflected laser beam hits the wall. Now the laser beam should hit the pod in the wall and
one step of the stairs leading to the exit will come down to you. Stand on this elevator step left to the pod you just hit with the laser beam and shoot one
of the portals to the wall behind you so that the laser beam does no longer hit the laser pod and so the elevator will go back up with you on it. From up here
you can see into the ditch, so shoot the other portal under the mirror cube to make it move out of the way of the laser beam. Once the laser beam hits the laser
pod in the ditch again the transport beam will start working again. So shoot one portal right where the transport beam hits the ground and the other portal onto
the single plattform on the ground where the broken cube is. This moves the broken cube up and once it hits the red switch on the ceiling the other step will come
down behind you. Step on it and remove one of the portals to make the cube fall down again and the step moves up again and you can proceed to the exit.
Test Chamber 12

All important white walls in this chamber have some smaller tileing on them. So shoot the blue portal there where the laser hits the wall for a start. The orange
portal goes to the tiled wall to the right of the exit in the same height as the exit. The laser beam will now hit the lower laser pod on the wall on the other site of the
hole in the ground and the small plattform will start moving. Once the moving plattform is all the way on the left stop it by placing the orange portal on the
white wall to the left of the moving plattform. Another portal on your side of the hole and you can jump over onto the moving plattform (that doesn't move at the
moment). Now you shoot the blue portal again where the laser ends and the orange portal on the tiled wallpice on the right of the exit. Let the plattform with you
on it move until it is halfway through the laser barrier, then shoot the orange portal to the tiled wallpice right above the one where the portal was just now.
This stops the moving plattform and also disables the laser barrier. You can now walk to the other side of the laser barrier and then shoot another orange portal
to the lower tiled wall and make the platform move again. Once the moving plattform reaches the other end jump down onto the solid plattform.
Here you wait, until the moving plattform reaches the other end again, then you shoot a portal right above the plattform where you just jumped onto the moving
plattform from. Now press the button and a mirror cube will fall down from the cube dispenser and onto the movable plattform. Shoot another portal right where you
are and you can jump onto the movable plattform again, but this time you are there with the mirror cube. Now you move the plattform and the cube to the other side of the laser barrier just like you
did before and once you are on the other side of the laser barrier you shoot the portal on the white wall on the left and above from the exit so that the
laser beam now comes at you, standing on the platform. Use the mirror cube
to aim the laser beam at the last remaining pod at the other side of the gap to open the exit and then jump down onto the solid plattform again. To get to the
other side again you need some more portal action and once you replace one portal the exit closes again, but hey, the mirror cube doesn't move, so just jump through the portal that is already pointing
towards the mirror cube and then again shoot the other portal to where the laser hits the wall. This finally opens the exit again and you are on the right side of the
gap.
Here you have to use a transport beam to directly enter the next chamber.
Test Chamber 15

Oh, there is no exit to test chamber 15! But Wheatley creates an exit for us. And if you look really close you can see a robot running out of the exit. This is probably
P-Body searching for an exit. But this is
not what it's all about, we have to reach the exit first...
Move towards the push button in front of the abyss and press it. A broken cube comes down but stops somewhere above you. But this doesn't matter, just turn around
and step on the big red switch on the ground to make the transport beam appear. A blue portal on the ceiling above the transport beam and an orange portal on
the wall to the left of the transport beam makes the cube move and it moves towards the abyss. Once it reached the end at the wall shoot the orange portal right
under the broken cube and the cube will now move towards you. But don't step off the switch in the ground too early, as this keeps the transport beam alive.
So shoot a portal through the hole in the glass wall in the one edge and another portal to the wall right next to it and carry the cube through the portals and
put it onto the second big red switch on the ground behind the glass wall and then leave this small room just like you came in. Step on the first red switch
on the ground again
to turn on the transport beam and make the orange gel move towards the ramp. As soon as a whole lava lamp full of orange gel is above the ramp step off the
big red switch and gel will splat down and the whole way from the wall to the ramp should be covered in orange gel. If not, just repeat what you just did until everything is covered in
orange gel.
Now we need the cube again, so get a new one or grab the old one, doesn't matter, but grabbing the old one is faster, and then put it onto the big red switch
in the ground out here to turn on the transport beam forever. Walk past the ramp on the left side and shoot a portal into the middle of the wall to the right,
right behind the blue energy wall and another portal to the ceiling above the transport beam. So the transport beam is now going all across the hall over there
and you can use the orange gel to get enough speed to jump over the ramp right into the transport beam that will bring you towards the exit. Wheatley tells another bad joke
and then we can go already.
There is no use in jumping into the transport beam directly and let it drag you all across the gap over there as the blue energy barrier deletes all portals...
and this is not good.
Test Chamber 16

An attack! But with 2 portals you are over the gap and inside the mean chamber in no time.
It's not that hard. Put one portal on the ground and another portal above the abyss under the gel dispenser and get over there. Once you are on the other side
of the abyss you put the blue portal to the wall at the end of the transport beam and the orange portal to the wall under the gel dispenser so that the transport
beam shines across the abyss. Now press the button here. The blue gel drips into the transport beam. As soon as some blue gel is next to you and the button, shoot
one portal somewhere else and the blue gel will drip onto the ground next to you. Now you rebuild what you just had with the transport beam shining across the abyss.
The next task requires you to be fast, so press the button and then use the blue gel next to you to jump into the transport beam. You should be ahead of the blue
gel. So move across the abyss inside the transport beam, the turrets (hopefully) won't hit you,
then jump out of the transport beam and step onto the big red switch on the ground.
The transport beam now moves backwards because it is orange. Wait until the blue gel is through the orange portal and moves towards the origin of the transport
beam. While standing on the red button you can see a small piece of white wall to the left of the turrets above them. You shoot the orange portal there and hope
that this was the right color and the transport beam is coming out of this orange portal now. Step off of the big red switch and the blue gel now moves away from the
origin of the transport beam again and towards the three turrets. As soon as the gel is above the turrets you shoot one portal somewhere else and the gel will
splat on the turrets and the turrets will jump around like crazy and then disappear.
Now you can walk behind the bulletproof wall and press the button there. A slanted wall appears. Now make the transport beam come out of one of the ground tiles
and jump into the beam and let it carry you up to the ceiling. Now look down and look for the color of the portal below you, the portal with the other color now
goes onto the slanted wall. You will jump directly to the exit!
Test Chamber 17

Here Wheatley prepared a nice trap for you, but you have to use the catapult anyways. This will bring you to a single plattform surrounded by even more
mean spiked plattforms ready to smash you and this is where the next and last chapter starts...
