The Orange Box: Portal Hints

Chamber 17 Advanced

  • 1 of 10: Move into the first room to find that one of the major differences in this advanced chamber is that your companion cube will be replaced by a bouncy metal ball.
  • 2 of 10: You can still get up the next room's ledges with the ball, but you'll have to be careful to get it to hold still before you jump onto it, and you'll need to reach down and grab it before it can roll away.
  • 3 of 10: Getting down the two energy orb corridors shouldn't be any harder than before. You may have to be a tiny bit more careful in deflecting orbs with the sphere, though.
  • 4 of 10: When you get to the big lift room, you'll find that the process of getting energy orbs into the lifts' three receptor devices has been greatly complicated.
  • 5 of 10: After all three lifts have been raised, get the companion sphere, portal your way up to the upper ledge, and jump across the lifts.
  • 6 of 10: When you get to the third lift, turn left and drop down to the lower ledge.
  • 7 of 10: Jump up the big steps past that to reach a room with a large glass wall on the other side of a pit.
  • 8 of 10: There are two strategies for getting yourself and your sphere through this area.
  • 9 of 10: You can now easily reach the exit area, where you'll dispose of your sphere in the same way as you did the cube in the normal version of this chamber. (See below if you need a reminder.)
  • 10 of 10: After the sphere is incinerated, the nearby door will open, allowing you access to the exit elevator.
