Portal 2 Hints
How can I get the hatch open?
1 of 13: Notice the three gel pipes that go up toward the hatch and just stop.
2 of 13: Opening the hatch probably has something to do with connecting other pipes up to those to get the gel pumping, so look around for a gel pump control room.
3 of 13: Up near the ceiling in one corner of the area is a small room with the words "GEL PUMP STATION" painted on the wall above it.
4 of 13: Look directly across the area from that room to see that there's a portal-friendly section of wall way up next to the ceiling, just above a huge cylindrical structure.
5 of 13: That could be your exit point for a portal fling, so look around for a way to gain some momentum for it.
6 of 13: There aren't any propulsion gel leaks in here, so you'll have to look for a high-up place to drop down from.
7 of 13: Look on the wall a ways to the left of the gel pump room to see a lamp shining down on one end of a walkway.
8 of 13: It's pretty high up, so put a blue portal on the wall under the lamp, then put an orange portal on the bottom of any portal-friendly wall so you can go through it.
9 of 13: Go along the walkway until you can turn left to find a drop-off. Crouch-walk slowly up to the drop-off, then look down to see that the floor directly below is portal-friendly.
10 of 13: Put an orange portal down there, then look up and to the right so you can put a blue portal on the high-up wall section that's across from the gel pump room.
11 of 13: NOTE: For your portal fling to have the best chance of working, the blue portal needs to be in the top center position on that wall section.
12 of 13: Drop into the orange portal to get flung into the gel pump room, then go over to the paradox poster on the wall when GLaDOS asks you to.
13 of 13: Go up to the control panel and use the red button marked "HATCH OVERRIDE" to get the hatch opened.
