Portal 2 Chapter 2 Test Chamber 7

This is the sixteenth level of the game, and takes place within a dilapidated Test Chamber. This level requires the player to utilize their knowledge of the Thermal Discouragement Beam, Buttons and momentum in order to successfully solve the Test Chamber. This level is also unique in that it features a damaged Emancipation Grid, which allows the player to unlock the "Preservation of Mass" achievement. The Weighted Companion Cube is also introduced here.

Hazards

 * Thermal Discouragement Beam

Trivia

 * Use the Companion Cube to block the beam then run to the wall by the victory lift and you can pull Wheatley from the wall.
 * He will not activate the button nor talk to you, but he can be used to block the beam if dropped face down.


 * Placing the companion cube on the button after collecting Wheatley and using momentum to fling yourself to the exit will cause GLaDOS to say: [[Media:GLaDOS sp_a2_pit_flings_future_starter01.wav|"Uh oh. You're stranded. Let's see if the cube will try to help you escape. Actually, so that we're not here all day, I'll just cut to the chase: It won't. Any feelings you think it has for you are simply byproducts of your sad, empty life."]].
 * She will then fizzle the cube on the button thus releasing a further cube form the Vital Apparatus Vent and say: [[Media:GLaDOS sp_a2_pit_flings_future_starter02.wav|"Anyway, here's a new cube for you to project your deranged loneliness onto."]] This can happen without grabbing Wheatley if you take the cube past the broken emancipation grill, leave it in, jump off of the platform where the exit door is, and place both portals on a nearby wall.


 * If you place a portal on the wall past the broken Material Emancipation Grill, you can then retrieve the Companion Cube. However, when you near the Chamberlock, GLaDOS will fizzle the cube and say [[Media:GLaDOS sp_a2_pit_flings06.wav|"I think that one was about to say 'I love you.' They ARE sentient, of course. We just have a LOT of them."]]
