The Orange Box: Portal Hints
Secret Area Notes
1 of 4: As you approach the entrance to piston area #1, look to the right to find some stairs that don't lead anywhere interesting.
2 of 4: Instead of going up the stairs, walk to the side of them until you reach a fence.
3 of 4: Use portals in the walls to get past the fence, then look for a room with a crouch-only entrance on the right.
4 of 4: As with all of Portal's secret areas, all it is is a secret hideout room that someone used in the past, probably right after the time when the computer first went insane.
