Walkthrough
- Once you reach the door, enter the Chamber, since there is no GLaDOS speaking in this advanced test.
- Since the Turrets are sealed in the boxes, you cannot knock the turret down. Instead, place a portal about the turret box, and a portal at the wall, then crouch under the panel.
- Upon landing, the turrets will fire the bullets at you, so you'll have to quickly move away or you'll get killed.
- Shoot a portal that the Turret shoots at you. Then place a portal at the wall and go through.
- Quickly go past the turret before the turret shoots at you.
- Grab these Weighed Storage Cubes from the wall panel. Quickly place a portal on the red X spot, then get the cubes in the portal. Quickly crouch under the cube to protect yourself from turrets.
- Sneak past the turrets and don't get killed. Quickly go to the safe place where no turrets shoot at you.
- Place a portal that leads to many cubes.
- To protect yourself, get as many cubes as you can. Place cubes blocking the turrets from shooting at you.
- You should have 5 cubes remanining. Go through the portal and quickly crouch from the turrets.
- Have one cube placed on the button. Shoot a portal behind the exit and get a cube away from the button. Always crouch with a cube to protect yourself.
- Go through the portal leading to the exit with a cube and quickly crouch.
- Fire a portal through the vents after you enter the portal behind the turret.
- Enter into the chamberlock quickly.
