This is the fourth level in Co-op mode of Portal 2 and the third chamber in the course. It introduces players to the use of the Thermal Discouragement Beams and Discouragement Redirection Cubes. Turrets are present as the primary hazard.


The goal in the first area is to get the beam through each of the nodes. In the second area the beam must be aimed at the panels and by using all four portals direct the beam to the receptacle.
