Portal 2 Hints

What's the advantage of doing it this way?

  • 1 of 5: Since you're still on the platform, you can turn to where you can see the cube that's in the low-down area.
  • 2 of 5: Fire a blue portal so that the cube falls through it and ends up on the other platform.
  • 3 of 5: Turn and reposition the blue portal onto the nearby wall so you can walk through it to get to the cube.
  • 4 of 5: You can then pick it up and drop down to place it on the other button.
  • 5 of 5: Note that this is just a faster, more optimized way to do things, and doesn't get you any achievements or other rewards.
