Portal 2 Hints
How can I get the exit door open so I can leave?
1 of 10: Did you notice the big red button on the ceiling of the chamber's lower section?
2 of 10: NOTE: To return to the lower section, put an orange portal on the ceiling where the excursion funnel hits it, then fire a blue portal through the funnel so that it hits a portal-friendly surface down in the lower section. You can then ride the funnel into the lower section.
3 of 10: You could reach the big red button if you used portals to extend the funnel up to it.
4 of 10: Put an orange portal on the ceiling where the funnel hits it, then put a blue portal on the floor directly under the big red button. (Note that it has a checkered pattern on it, making it easy to locate.)
5 of 10: You could then ride the funnel up to the button, but as usual, you can't hold down the button and go through the exit door at the same time.
6 of 10: That's where the franken-turret in the chamber's upper section comes in.
7 of 10: Ride the funnel to the upper section if you're not already there, then look for a way to get to the franken-turret's ledge.
8 of 10: Pick up the franken-turret and drop down to the floor, then drop the franken-turret and let it wander around if it wants to while you get the excursion funnel extended to the big red button.
9 of 10: Looking down through the floor opening that the funnel comes up through, relocate the blue portal to the floor section that's under the big red button.
10 of 10: Now all you have to do to open the exit door is stick the franken-turret into the funnel and drop it. It'll be carried along until it's pressed up against the big red button.
