Player 2 : You should place your portals on the opposite target and on the other wall panel just above the entrance.
Both Players : You need to synchronise this next move, so both of you need to stand beside the Faith Plates and count down. At the same time, stand on the Faith Plates, so the two of you are catapulted into the red switches at the same time, opening the door to part 2.
Player 1 : Run over to the lift in the top left-hand corner of the room and fire off your second portal on the ground just in front of the lift.
Player 2 : Quickly take the Displacement Cube down into the narrow corridor (with the spikey, smashy, wall trap), and aim the Cube under the laser so it’s hitting the receiver on the wall, this’ll in turn, start raising the platform that player 1 is on.
Player 1 : Now once the lift has nearly reached its maximum height, drop down into the portal directly below you and you and the velocity gained will fling you into the Arial Faith Plate on the wall, and into the switch that stops the spike wall from squishing you both.
Player 2 : Keep your metallic mitts on the Cube and bring it with you down to the room that leads to the exit. Now go stand beside the Arial Faith Plate (but don’t step on it) and wait for player 1 to prepare the next bit for you.
