The Orange Box: Portal Hints
How can I get through this test chamber?
1 of 10: Looking around, you'll see that there isn't much in it except a button-opened door.
2 of 10: Unfortunately, no cubes dropped down with you.
3 of 10: Fortunately, you don't need them.
4 of 10: Try standing on the button to open the door.
5 of 10: Look at the wall of the hallway that's past the door.
6 of 10: It's made of concrete. Give you any ideas?
7 of 10: Toss a blue portal through the door while it's open.
8 of 10: Then fire an orange portal into any wall or floor and go through it.
9 of 10: Past the door, move along to find the elevator shaft.
10 of 10: There's no elevator in it, so the only way to leave the test chamber is to drop down to the bottom of the shaft.
