Follow this walkthrough for Portal 2's Chamber 8 in Chapter 2. Learn how to solve the puzzles involving the Displacement Cube and laser beams to reach the exit.

Alright, let's tackle Chamber 8! This one's pretty straightforward once you know the trick.

Walkthrough
  1. 1
    First things first, you'll see a platform that needs to appear before you can really get going. Wait for it to show up, then head towards the back of the room. Look for a spot to the upper right of a button. Place your first portal there.
  2. 2
    Now, hit that button! This will release a Displacement Cube.
  3. 3
    Quickly, look through the small gap you can see and place your second portal on the wall within that gap.
  4. 4
    Head through the portal you just created. You'll pop out right where the Cube landed.
  5. 5
    Grab that Cube and bring it back through the portal with you.
  6. 6
    Now, you'll need to get that Cube over to the laser beam. Line it up perfectly with the beam receiver and drop it in place.
  7. 7
    Once the laser is activated, you can step through the portal again, or just run through the displacement barrier. The exit is now open!
Tips
  • Don't rush placing the second portal; make sure you can see through the gap clearly before you fire.
  • The Cube needs to be *directly* in the beam receiver for it to work.
