Portal 2 Hints
How can I leave this chamber?
1 of 12: Once you get a franken-turret over to the area with the exit door, you'll need to do two things in either order: get the franken-turret pressed against the big red button, and get yourself onto the exit platform.
2 of 12: Look at the spot that's directly across the room from the big red button to see a portal-friendly wall section. If you moved the blue portal onto that wall section, the excursion funnel would be extended onto the button. (Try it to be sure you're looking at the right wall section.)
3 of 12: Now you need to figure out how to use that to get yourself onto the exit platform and the franken-turret onto the button.
4 of 12: Notice that the floor in the area underneath the wall section that you need to put the blue portal on is portal-friendly (and checkered).
5 of 12: What if you were to put the blue portal on the floor first, then put the franken-turret and/or yourself into the extended funnel?
6 of 12: After whatever is in the extended funnel is pressed against the ceiling, you could relocate the blue portal onto the above-mentioned wall section to get the item dropped into the new extended funnel and pushed across to the big red button.
7 of 12: Put the blue portal on a checkered part of the floor, then pick up the franken-turret and push it into the extended funnel.
8 of 12: Release it and let it float up to the ceiling, then get in the funnel and float up under it.
9 of 12: Reposition the blue portal onto the wall section that's directly across from the big red button, thereby causing you and the franken-turret to fall into the new extended funnel. (Note that you and/or the franken-turret might fall wrong and get dropped onto the floor or into the original funnel section.)
10 of 12: If it works, you and the franken-turret will be pushed along toward the button, with you in the lead. When you get over the exit platform, push your way out of the funnel so that you fall onto the platform.
11 of 12: The franken-turret should then get pushed against the big red button, allowing you to go through the exit door.
12 of 12: ALTERNATIVE: Due to the chance of you and the franken-turret colliding wrong and getting ejected during the funneling process, you might want to first get yourself onto the exit platform, then get the franken-turret onto the big red button. The way to do that is to drop the franken-turret on the checkered floor section (use the Item Flinging Tip to help ensure that it can't move around after it's dropped), then put the blue portal on another part of the checkered flooring. Funnel yourself onto the exit platform, then funnel the franken-turret onto the button.
