The Orange Box: Portal Hints
Where can I go from this ledge area?
1 of 7: The door doesn't open, so look around for something to toss a portal through.
2 of 7: Check out the back wall with all the stains on it.
3 of 7: Look above the stains to find a small square grate.
4 of 7: You can fire portals through it, so look through it for something to fire one at.
5 of 7: Get to where you can see one of the concrete walls that's near the top of the grate, then fire a blue portal onto it.
6 of 7: Shoot an orange portal onto a nearby wall, then walk through it.
7 of 7: NOTE: You'll be walking in sludge after you go through the portal, but it won't be the toxic kind.
