Portal 2 Hints
How can I get into the test chamber?
1 of 7: Look around the observation room for a way to get to a new walkway.
2 of 7: Next to the two filing cabinets is a broken vent grating.
3 of 7: Looking through it, you'll see a portal-friendly wall surface.
4 of 7: Fire a blue portal onto it, then put an orange portal on the wall to the right of the broken grating.
5 of 7: Go through the orange portal to drop onto a walkway, then move along it to reach a small lift.
6 of 7: Get on it and wait to be elevated, then go along the upper walkway until you can drop down into a room with two doors.
7 of 7: Go through the door that's past a force field to enter the test chamber.
