Portal 2 Walkthrough → Chapter 8: Itch (Part 1)
From the upper room, we watch as Wheatley scolds the turrets for not being able to press the button. In the corner, through a damaged hatch, we create a portal to the other side. We take the elevator up and find ourselves in the same chamber with the test turrets. We pick up one of the cubes and place it on the button. After talking with Wheatley, we head to the first test. This one is simple: activate the console, create a portal on both the opposite side and ours, and proceed to the exit. Wheatley is clearly dissatisfied, so we try the same test again.
In the next test, we stand on the gravity beam and wait for it to carry us upward. We create a portal above the gravity beam and another on the wall opposite the cube. We stand on the beam and are transported directly to it. After collecting the cube, we create a portal below, in a specially marked spot (alternating squares) and, naturally, above the gravity beam. The cube will automatically attach to the button, and we can proceed. In the second test, we jump down onto the gravity beam, create one portal in its direction and one on the perpendicular wall.
Then, just as quickly, create another one while moving, also perpendicular. It's crucial to act quickly at this point. Create the final portal at the marked spot on the floor. Activate the console and watch where the cube falls. Cast a gravity beam underneath it and lift it toward us. Create another gravity beam in the designated spot under the button. In the next challenge, create a portal in the direction of the gravity beam and another one on the surface opposite the other side. Once you've reached the other side, activate the console. Noticing where the cube falls, cast a gravity beam underneath it.
Quickly move to the right and create a portal on the opposite side. This creates a gravity beam, which we used to cross and will give us the cube. Create a gravity beam right next to the marked surface, which we'll land on if we step on the air panel. Grab the cube and step on the air panel. This will put you as close to the other side as possible and allow you to safely jump off the gravity beam. Now we need to somehow attach the cube to the button.
Create a portal at the base of the beam and on the floor, as close to the exit as possible. Send the cube first, then yourself. Once we're stuck to the ceiling, create a portal on the surface opposite the button (marked). The cube reaches the button, and we jump down to the exit.
In the fourth test, we'll start by destroying the defensive turret: a portal in the direction of the beam and on the wall on the other side, where the laser is aimed. Create a portal on the wall opposite the cube. Stand on the button, and the beam's direction changes. This will easily deliver the cube to us. Place the cube on the button and cross to the other side. Remove the cube from the button by aiming the gravity beam at it. Create a gravity beam in front of the exit and jump to it (if you don't remove the cube from the button, nothing will work).
In the fifth test, we'll create a gravity beam between the air panels. We'll get stuck in it during our flight. We'll remove the portal in the beam's direction and quickly create one on the half-bent panel. Before activating the console near the exit, we'll create another gravity beam between the air panels. The cube will follow our path, so we'll do the same for it. We'll place it on the button and proceed.
In the sixth test, we'll try activating the console. We'll monitor the cube's trajectory and, to prevent it from passing through the splitting wall, create a portal in the direction of the path and another one in the cube's trajectory so it falls down. If the cube lands on the edge, it's easy to retrieve, but if it lands in the center, simply running across and grabbing it won't work. Creating a path in front of the turrets can provide protection. After pulling out the cube, we'll grab it and try to fly it to the metal structure using the air panel.
To prevent it from flying over, create a path in front of it, through the right wall. Let's leave the cube for now and create protection from the turrets. Move along the structure and place the cube on the button on the other side. Return to the exit and leave the chamber. In the eleventh trial, we first need to reach the cube on the elevated area on the left. To do this, create a portal in the direction of the gravity beam and on the floor between the air panel and the half-bent surface.
