Portal 2 Walkthrough → Chapter 8: Itch (Part 2)
Attached to the ceiling, we remove the gravity beam portal and quickly create one on the half-bent surface. We block the laser with a cube. We create a portal on the half-bent surface above the laser and another on the other half-bent surface. We stand on the air panel and fly to the guide cube. We place it in front of the laser and aim the beam at the wall (90 degrees).
We create a portal in the direction the laser is aimed. The second portal is opposite the hole next to the platforms. We place the cube on the floor, opposite the button. We stand on the first lowered platform. We remove the guide cube, creating a portal underneath it. The platform we are standing on has risen. We move to the adjacent platform. We aim the laser at the hole creating the gravity beam.
Create a portal in the direction of the gravity beam and on the floor where the cube is located. Wait for the cube to touch the button and then exit the chamber. In the twelfth trial, there are two openings on the opposite side. The lower one controls the platform's movement, while the upper one controls the laser grid in the middle. Move the platform so that it's flush with the left side.
Jump onto it and move it to the right. When exactly half the platform passes through the lasers, stop it. Aim the laser at the upper opening. Move to that same half and resume moving the platform. Jump down to the console. Activate it when the platform is as far to the left as possible. The cube falls onto the platform, and we also jump on it. Repeat the steps, but this time use the guide cube to aim the laser at the opening on the exit side. The door opens, and we can head for the exit.
In the next test, activate the console. Deliver the cube to us using the gravity beam, and to do this, stand on the button. There's another button in the isolated space. Place the cube on it and return to the gravity beam button. Create a portal in the direction of the gravity beam and on the wall in the middle, which is facing the ramp. This will deliver the orange gel along the entire path and ramp. Look into the distance; there's a wall to the right. Create a portal as close to us as possible, place the cube on the gravity beam button, and create another portal in the direction of the gravity beam.
To accelerate, you need to turn around and enter the gravity beam to stabilize yourself so you don't fly out of its range. For the next test, we'll teleport to the console. We'll be transporting blue gel. To do this, create a portal in the direction of the gravity beam and on the wall next to the blue gel faucet. Activate the console, and the gel will flow in the direction of the beam. Spray the area near the console so you can jump up to the beam.
Then create another portal, activate the console, and quickly jump onto the beam. You must reach the button on the other side before the gel hits the wall. Pressing the button changes the beam's direction. Wait for the gel to enter the portal. Quickly create a new portal above the turrets (on either the left or right surfaces) and be sure to step off the button.
When the gel is above the turrets' heads, remove the portals, thereby destroying them. Activate the console behind the glass; all that's left is to fly to the exit. Climb to the ceiling using the gravity beam and jump down, having first created a portal on the half-bent surface.
