The Orange Box: Portal Hints

Chapter 7: Testchamber 15

1 of 10:
The first obstacle that you'll encounter in Chamber 15 is a glass wall with a large object-destroying force field above it.
- How can I get past the glass wall?
2 of 10:
Move through the doorway past the glass wall and on to a room with a raised lift and an energy orb bouncing around.
- How can I get the orb into its receptor device?
3 of 10:
After you ride the lift up, go down the corridor to reach another large room with a glass-wall-and-force-field setup that you need to get past.
- How can I get over this glass wall?
4 of 10:
As soon as you get over that glass wall, you'll find another one nearby that you'll need to get over.
- How can I get over the next glass wall?
5 of 10:
Once you're past that, you'll need to get the bouncy energy orb into its receptor.
- How can I get this orb into the receptor?
6 of 10:
Unfortunately, the moving platform that the orb is now powering is back on the other side of the nearest glass wall.
- How can I get back across the glass wall?
7 of 10:
After you get back to the area between the glass walls, you'll find that the moving platforms are going the wrong way.
- How can I get to the room at the other end of the moving platform corridor?
8 of 10:
You'll find a bouncing energy orb in the middle of the room past the moving platform corridor. As with most energy orbs, it needs to be directed into its receptor.
- How can I get this orb into its receptor?
9 of 10: The orb will power the third lift in the room, which will lower to the floor.
10 of 10: Ride that lift up to reach the elevator that'll take you to Chapter 8: Testchamber 16.
