Portal 2 Hints
How can I enter the test chamber?
1 of 5: Move up to the rubble that's blocking the chamber entrance, then look through it and to the left.
2 of 5: An orange portal will appear on a high-up extended wall section. How could you use it to enter the chamber?
3 of 5: Look around for a portal-friendly surface nearby.
4 of 5: The floor next to the rubble can be used, so fire a blue portal onto it.
5 of 5: Go through the blue portal to drop out of the orange portal and land on the test chamber's main floor.
