Portal 2 Hints

How can I get up to this chamber's upper area?

  • 1 of 10: If you look across the chamber and up, you'll see a lift that's stuck in its "up" position.
  • 2 of 10: Notice that the nearby laser beam is going straight from its emitter to a receptacle. That's probably what's keeping the lift up.
  • 3 of 10: If you block the laser beam with something, the lift should lower.
  • 4 of 10: The only object you can use for that is the companion cube.
  • 5 of 10: Jump over the laser and pick up the cube, then drop it in the laser's path. (Note that the first two times you try to do this, GLaDOS will "accidentally" fizzle the cube, and you'll have to wait for another one to drop down.)
  • 6 of 10: Once you get a non-fizzled cube set in the laser's path, the lift will lower, and you'll be able to get on it.
  • 7 of 10: Now you'll have to get the cube out of the laser's path so the lift will go back up.
  • 8 of 10: Since you want to do that without getting off of the lift, you'll have to use portals.
  • 9 of 10: Put a blue portal on the floor under the cube, then put an orange portal on one of the portal-friendly walls.
  • 10 of 10: NOTE: If you instead put the orange portal on another spot on the floor that's under the laser beam, the cube will bounce up and down through the portals, causing the lift to jerk up and down. (Unfortunately, there's no Stutterf**k achievement.)
