Portal 2 Hints
Gamma Enrichment Sphere and Elevator Shaft
1 of 8: Go down the walkway past the elevator, then stop at the walkway's broken-off end.
2 of 8: Just ahead is a tube that's spewing conversion gel out in large quantities. That's good, since if you look around the chamber, you'll see that there aren't any traditional portal-friendly surfaces.
3 of 8: Drop into the gel tube's room, then use portals to splash gel onto the floor outside the walls so you can portal yourself out there. (Note that some of the wall sections are mesh, which means that both portals and gel can pass right through them.)
4 of 8: Explore around the outer part of the chamber until you find the high-up exit door, then visually follow its walkway along until it ends at a large platform.
5 of 8: Look on past the platform to find a slanted surface with a lamp on it down near the floor. You'll need to portal-fling yourself from that surface onto the large platform.
