Portal 2 Hints
Now how can I get to the exit door?
1 of 11: With the franken-turret holding down the big red button and reversing the flow of the excursion funnel, it'll be easy to get across to the exit area.
2 of 11: Put the blue portal onto the lower part of the back wall, making sure it isn't directly across from the big red button. (You don't want the franken-turret pulled off of the button.)
3 of 11: Step into the extended funnel and ride it across to the other side, then push your way out of it.
4 of 11: Now you need to get up to the exit door's ledge.
5 of 11: Notice that the floor in front of the ledge is portal-friendly. What if you put the blue portal onto it?
6 of 11: Having an extended funnel section next to the exit ledge is what you need, but for it to do you any good, it'll have to be able to take you from the floor up to the ceiling. It won't do that right now.
7 of 11: The reason it won't is because the franken-turret is still on the big red button, which reverses the funnel's flow direction. You'll need to find a way to get the franken-turret off the button without going back over there.
8 of 11: Do you remember how you got rid of the turret earlier?
9 of 11: There were actually two possible ways. The one that used the excursion funnel is the one that's useful to recall now.
10 of 11: Place the blue portal on the wall opposite the big red button so the extended funnel will pull (and then push) the franken-turret off of the button.
11 of 11: After you do that, put the blue portal on the floor next to the exit door's ledge, then ride the extended funnel up to where you can move onto the ledge.
