Player 1: Set a portal at the end of the light bridge and then on any part of the wall up and to your left. This will create a bridge across the acidic water that both of you can cross over. Drop down onto the platform below and then set your exit portal on the wall panel in the left-corner by the water just ahead of you.

Player 2: Follow player 1 and once you step onto the second light bridge, look for the two wall panels in the far right-hand corner. Get a portal on each of these so the bridge is extended above your heads, crossing the water to your left. Drop down off the light bridge and towards the second part of the test.

Part 2

Player 1: As soon as you enter the room, turn to your right and fire your first portal up at the light bridge in the upper left-hand corner of the room. Now ask player 2 to hit the Arial Faith Plate in the middle of the room and as soon as they hit the roof, fire a portal at the wall up in front of you, so it creates a bridge that player 2 can land on.

Player 2: Turn around to face the exit and get your first portal where the light bridge meets the wall, then turn back around and set a portal directly under the light bridge in the upper left-hand corner of the room. Run through both portals and hit the switch tucked away from view in the corner (it’s in an alcove on your right).

Player 1: The chute will drop a round weighted ball, so pick this up and then orient yourself before standing near the Arial Faith Plate.

Player 2: Fire a portal at the very top of the room (so it covers the blue force field), otherwise you’ll vaporise the ball needed to exit the level. Once player 1 steps on the Faith Plate and hits the light bridge with their head, immediately get a portal underneath them, so they can land on it.
