Portal 2 Hints
What do I need to do?
1 of 4: Notice that you can't move around at all, and that your view is limited to a small area.
2 of 4: You need to fire off one last portal, and you aren't going to *believe* at what!
3 of 4: You see that big hole in the lair's ceiling that the moon is showing through?
4 of 4: This is even more insane than anything else that's happened in the game so far, but you need to fire a portal (either orange or blue) at the moon. Seriously! Don't overthink it -- just do it and enjoy the ending, which includes a new song sung by GLaDOS.
