Chapter 2 - Test Chamber 03
sp_a2_dual_lasers.bsp
This is the thirteenth level of the game, and takes place within a dilapidated Test Chamber. This level introduces the player to multiple Thermal Discouragement Beams within a single chamber.
Grab the cube and jump to the platform in the middle of a chamber. Put the cube on the platform such that it redirects a lower Thermal Discouragement Beam to the receptacle. Then go back to the original location of the Discouragement Redirection Cube, look up to find another receptacle on the ceiling.
Place a portal on the wall where the upper Thermal Discouragement Beam makes contact and place another portal under the second receptacle.
After both beams are redirected to the receptacles the exit doors will open, proceed to the Chamberlock.
There is Wheatley hidden in this chamber, right under the panels that lift to give you access to one of the lasers. He appears only for a brief moment though.
