Portal 2 Hints
How can I get past the laser grill?
1 of 8: Have you tried redirecting the laser into the upper receptacle yet?
2 of 8: Try it now by moving the blue portal up to the upper special wall section.
3 of 8: That'll stop the moving platform (because its receptacle isn't getting the laser anymore) and it'll shut off the laser grill.
4 of 8: What if you were to move the laser from the bottom receptacle to the top one when the platform was partway through the laser grill?
5 of 8: Stand near the edge of the platform that's farthest from the grill, then move the blue portal to the lower special wall section to get the platform moving.
6 of 8: When the platform is about halfway through the grill, quickly move the blue portal to get the platform to stop moving.
7 of 8: Put the blue portal on the top special wall section to shut off the grill, then move through it and over to the platform's other end.
8 of 8: You can then put the blue portal back on the lower special wall section to get the platform moving again.
