Chapter 1 - The Courtesy Call

Chamber 5

As soon as you enter Chamber 5, fire a portal down at your feet and you’ll soon fall through and into the main room itself.

There's a Companion Cube in a delivery chute located in the top right-hand corner of the room. Fire your portal at the ground below it and then press the red plunger button behind you.

This’ll cause the Cube to fall through to where you are, so pick it up and set it on the large red button on the floor. Doing this will raise a flight of stairs on your left, so walk up here and you should notice two more plunger buttons overlooking the acid below.

Fire a portal at the slanted wall on the left first, then press the left button first (deploying the Cube) and then press the right-hand button as the Cube is dropping. This'll raise the platform, preventing the Cube from hurtling into the acid.

With the Companion Cube safely on the ground, run back down, pick it up and take it back up to the red button on the ground. Doing so will open up the exit to the next test.
