Portal 2 Chapter 2 Test Chamber 2

This is the twelfth level of the game, and takes place within a dilapidated Test Chamber. This chamber introduces the Discouragement Redirection Cube, and the way in which it can be used in combination with the Thermal Discouragement Beam in order to activate Panels. This level also introduces the ability of the Redirect Cube to act as a Weighted Storage Cube and activate Heavy Duty Super-Colliding Super Buttons.

Hazards

 * Thermal Discouragement Beam

Walkthrough
Upon entering the room head to the left to a small cut off alcove which contains a Discouragement Redirection Cube. Shoot a portal through the grating on the floor inside and place one somewhere on your side. Enter through and pick up the Discouragement Redirection Cube. Return back through your portal to the main room and to the Thermal Discouragement Beam. Place the Discouragement Redirection Cube such that it intercepts the Thermal Discouragement Beam and redirects it into the receptacle. Upon successfully doing this a staircase will appear to the exit. Proceed to the top of the staircase and place a portal on the floor next to you. Place the second portal underneath the Discouragement Redirection Cube you left behind and catch it as it falls through the portal. Place it on the Heavy Duty Super-Colliding Super Button and exit through the doors.

Bugs

 * When Wheatley appears in the wall it is possible to grab him if the player is quick enough.
