Portal 2 Hints
How can I burn all the turrets?
1 of 8: When you first enter the chamber, run past the turret that's behind a vent grating on your right.
2 of 8: Past that is a room with a big red button and a laser emitter in the ceiling.
3 of 8: Stand on the button to find that it activates the laser emitter. Of course, getting off of the button will deactivate the emitter.
4 of 8: Looking through the glass wall near the emitter, you'll see that there's a storage cube and a redirection cube past three turrets.
5 of 8: After moving both cubes to the button room, put the storage cube on the big red button to get the laser to fire continuously.
6 of 8: Relocate your orange portal somewhere, then use the redirection cube to burn the four turrets you can see past the nearby glass wall.
7 of 8: These are apparently special glass walls that laser beams can pass through, so just move the redirection cube into the laser and turn it so the beam hits all four turrets.
8 of 8: As for the turret you ran past while entering the button room, you can just leave it and move on, or you can destroy it to discover a secret area.
