Portal 2 Hints
Pump Station Beta
1 of 6: Go along the walkway past the elevator to find a large room with a boarded-over exit door.
2 of 6: Go through the door to enter the pump station, then find a way to get yourself to the high-up walkway that's directly above the big "Pump Station Beta" sign.
3 of 6: Enter the room with the big machine console in it, then use both of the large switches on it to start pumping gel into the upcoming test chambers.
4 of 6: Doing that opens a nearby door, so go through the force field past it and over to the EXIT door.
5 of 6: Push it open, then go through it and look up. Directly ahead of you is the elevator that leads to the next chapter, but the walkway leading over to it is broken off.
