Portal 2 Hints
How can I get to the third chamber's entrance?
1 of 11: After exiting the second chamber, go forward to find some stairs. Past them, go over to a small stick-out platform.
2 of 11: Get on it and look up to see the third test chamber above you, then look down to see a couple of ledges with portal-friendly surfaces near the toxic lake.
3 of 11: NOTE: If you drop down and/or portal to a ledge and find yourself stuck, you can portal yourself back to the stick-out platform using its portal-friendly ceiling.
4 of 11: If you look across to the second ledge and then up, you'll see a portal-friendly wall section that's not far below a broken-off walkway section.
5 of 11: However, if you use that high-up wall section (and the portal-friendly surface on the ledge directly beneath the stick-out platform) to fling yourself, you'll just end up in a spot where you can't go anywhere but down to the second ledge.
6 of 11: But what if that spot had some repulsion gel on it? Portal-flinging yourself onto it then might bounce you up to a walkway section.
7 of 11: After that's done, go back to the stick-out platform and carefully crouch-walk up to its edge.
8 of 11: Look down and place a blue portal on the ledge below so you can drop into it, then do so to get flung onto the gel, which will bounce you onto a walkway section.
9 of 11: Move around on the walkway until you find a portal-friendly surface, then look directly above it to find another one.
10 of 11: Put an orange portal on the lower surface and a blue portal at the top of the higher surface, then jump through the orange portal to drop onto a higher walkway section.
11 of 11: You can then use it to get to the third test chamber's entrance.
