After the great and surprising confettistorm we finally reach a chamber that is bigger than the chambers before. So come on, there is a lot to do here.
Luckily you are behind the light bridge and so you are safe from the turret. So look around and you will see another place to be at the other end of the chamber
with 4 movable platforms in front. Shoot a portal to the wall there and shoot another portal to the ground right behind the light bridge to still be
safe from the turret. Now jump into the portal and you are even safer from the turret as you are on the other side of the room and behind the turret now.
Well, up here you will see two
cube dispensers to your left. Shoot a portal right in front of the cube dispenser that is further away. Shoot the other portal to the ceiling, right
there where the light bridge ends. Now there should be a light bridge right in front of the cube dispenser. So now is the time to press the button up
here and watch what happens, both mirror cubes will land over there, near to the far away cube dispenser. And you need both of them, so if one of them
will fall into the water locate the portal in front of the cube dispenser closer to the cube dispenser to stop the cubes in flight.
From up here you can also move the cubes by placing a portal somewhere on a wall and the other portal right under the cubes. So move one cube right into the booth with
the laser beam coming in and the other cube as good as possible behind the bulletproof glass wall in the middle of the chamber. Now use the wall behind
you to place a portal there and move yourself into the laser beam booth.
In the laser beam boot you use the mirror cube to reflect the laser beam along and a little bit behind the bulletproof glass wall. Now place a portal behind
the glass wall and move there, grab the cube there and reflect the laser beam onto the turret on the other end of the room. Now the turret is gone
for good and you have all the time you need. Walk back to the laser beam booth now and reflect the laser beam so that it hits two of the four blue
bumpers on the ground. And with the second mirror cube you walk to the end of the laser beam and reflect the beam straight through the last two bumpers
on the ground and right into the laser pod to open the exit.
GLaDOS now calls your parents or at least tries to, but noone answers. But this doesn't matter anyway, so place a portal on the ceiling where the light
bridge ends and another portal on the outsides of the laser booth to finally reach the exit and take the elevator to the next chamber. Wheatley appears
and tells you some stuff, so maybe he is right. Hang in there!
In this chamber we have two of these blue hats that want to be hit by a laserbeam. So just leave the first mirror cube right at the entrance to this
chamber where it is and jump down. You will need this mirror cube later on. Another mirrorcube is down here, just sitting on the ground and another one
way up on a small single pillar on the right of the entrance. And exactly this is the cube we are getting now. Place the blue portal right above the catapult,
there where the circles are drawn on the ceiling and the orange portal right on the ground down here. Jump into the orange portal and you will get
catapulted high up in the air. While you are up in the air turn around to face the mirror cube on its pillar and then shoot the blue portal to the
wall next to the cube (close to the edge), so that you are catapulted onto the mirror cube once you get shot out of the blue portal. The mirror cube will
now land on another pillar, but this time closer to the ground. But still unreachable from the ground. But the ceiling above this pillar can hold a
portal, so shoot a blue portal there and jump into the orange portal on the ground again to finally reach the mirror cube.
So we use this mirror cube now. Have a look where the laser beam is pointing right now and use portals to get up there with the mirror cube. Up here
you use the mirror cube to point the laser beam to the blue bumper hat diagonal across the chamber and then jump down again. Now get the second mirror cube
that is already down here and drag it close to the catapult. Put the blue portal on the markings above the catapult and the orange portal on the ground
again and then throw the mirror cube into the orange portal on the ground. Once the mirror cube is high up in the air put the blue portal high on the
wall left to the smaller pillar where the first mirrorcube ended. The mirror cube will now fly across the chamber to the place where the laser beam is
now pointing to. Now you get yourself up there too in the same way you got the mirror cube up there. Here you use the mirror cube to point the laser
beam to the blue bumper hat at the entrance to the chamber.
And now you portal to the entrance where the laser beam is pointing to at the moment. The ceiling above there is perfect for another portal. There is
still a mirror cube around here so grab it and shoot all the turrets in front of the exit. Then you aim the laser beam to the laser pod and the exit
opens up. You reach the exit by again catapulting you up with one portal above the catapult and one on the ground and then, while you are in the air
you shoot a portal to the opposite wall of the exit and suddenly you are already standing in front of the exit to the elevator to the next chamber.
If you know what you have to do this chamber is quite easy, so I just tell you what to do here, okay. Then it will be easy.
Place a portal to the wall, right where the one
laser beam coming from the wall that is displaced by the mechanical arms hits the wall and another portal to the pillar opposite the three laser pods.
So the first laser beam already hits the left laser pod. Now you just use the two remaining mirror cubes to aim the last two laser beams through the
portals into the laser pods and you are done here. The laser beam coming from the ceiling has to hit the right laser pod so the other laser beam
parallel to the ground goes into the middle laser pod and the exit is already open.
A clever Portal 2 player called lost4468 uploaded a video to YouTube in which he solves this chamber without using a single portal.
Pretty cool, here is the video:
It all starts so innocent. Place a portal at the end of the light bridge and one up there next to the button. Walk through the portal and use the
button up here. The weighted companion cube is coming out of the cube dispenser and as soon as you are going to get it the lights go out and even the
light bridge is gone.
Wheatley! He did it and now helps you escape the test chambers shortly before room 22/22. So follow him on the linear way through the hallways in the
back of Aperture Science.
Even though the music is quite hectic you have no need to hurry and can have a look at how it looks backstage of Aperture Science.
GLaDOS will try to lure you into another really easy test chamber with nice green stuff at the exit but just ignore her, as this chamber is a trap.
But you will earn an achievement if you do get in though.
Follow the light bridge to the other way until you reach a chamber with three turrets inside. Destroy them and after the last turret there is a concrete
wall you can shoot a portal at. Now turn around and see through the walls surrounding you to find another concrete wall out there to shoot a portal at
and get out of here. Now follow Wheatley again until you are at another turret. The old shoot a portal to the wall and another portal under the turret
trick works here too so do this. Afterwards you just walk up some stairs into a huge open room with lots of test chambers surrounding it and in here
you better keep running the only possible way or you will be crushed. Once you reach the elevator you are safe and this chapter is over and you are
fleeing from GLaDOS. But if your escape is successful depends on you, so turn the page...
