The Orange Box: Portal Hints

Chapter 9: Testchamber 17

  • 1 of 9: Move forward and wait while your "companion cube" drops down from a cube tube. It's a regular storage cube that has little heart shapes on it. (Man, that computer is cray-ZEE!)
  • 2 of 9: Past that is a room with some ledges in it that you can't quite jump onto.
  • 3 of 9: Right past the ledges are a couple of dangerous energy-ball corridors that you have to go down.
  • 4 of 9: Past those deadly corridors is a large room with three lifts that you need to raise.
  • 5 of 9: The lifts are connected to three energy orb receptor devices. Each time you get an orb into a receptor, the next lift in the series is raised up. You can do them in any order, but I number the receptors in the order that I recommend you do them in.
  • 6 of 9: Once all three lifts are raised, use portals to get yourself back up to the high-up ledge.
  • 7 of 9: Then use the lifts as "stepping stones" to jump across in order to reach the next area.
  • 8 of 9: In it, you'll have to dispose of your companion cube before the computer will let you use the exit elevator.
  • 9 of 9: After the poor cube is incinerated, the other nearby door will open, allowing you to take an elevator to Chapter 10: Testchamber 18.
