Portal 2 Chapter 2 Test Chamber 3

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.

Hazards

 * Thermal Discouragement Beam

Music
1. Exile Vilify - 4:46 by The National

Bugs

 * If you activate one of the Thermal Discouragement Beam receptacles, then deactivate it and activate the other one (both with portals), GLaDOS will congratulate you the way she would if you finished the test normally, despite the test wasn't actually completed, as in, you can't go through the Chamberlock.

Easter Eggs

 * You can see one of Rat Man's Dens in this chamber. To the right of the exit you can see a broken wall leading to his den. Two of his trademark murals are painted on the walls and there is a radio tucked away in a corner – it’s the only place in the game you’ll hear a song written and composed specifically for Portal 2, The National’s “Exile Vilify.” The lyrics are incorporated into the murals.

Trivia

 * 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.
