Portal 2 Hints
Where do I set my portals to get that done?
1 of 5: While adjusting the redirection cube, look around for any portal-friendly walls that you can point the laser beam at.
2 of 5: Standing next to the cube and looking directly across the chamber, you'll see one small wall section that's portal-friendly.
3 of 5: Open an orange portal on that wall section, then adjust the cube if necessary to get the laser to go directly into the center of the orange portal.
4 of 5: Return to the second barrier's area by dropping down to the main floor and using its faith plate, then look for a portal-friendly wall surface up there.
5 of 5: There's one directly across from the receptacle, so that's where you place your blue portal.
