Portal 2 Hints
So how can I use portals to get up onto that floor?
1 of 5: Search the room from your position to see if you can spot any portal-friendly surfaces.
2 of 5: There's only one you can use.
3 of 5: It's the large extended wall panel that GLaDOS lowered when you approached the room.
4 of 5: Fire one color of portal onto it, then go back around the corner and put the other color of portal on any of the portal-friendly walls.
5 of 5: You can then go through the portal to drop onto the room's higher floor.
