Player 1: Make your way through the force field and into the other half of the room. You'll want your two portals on the angled wall panel in the left-hand corner and also on the angled wall panel in the lower right-hand corner of the room.

Now hit the red plunger and a Companion Cube will drop down onto the Arial Faith Plate, carrying it through the same portals you just passed through. As soon as the Cube nears you, grab it and then drop it down on the ground for player 1.

Make your way up onto the ledge to your left and walk around the left-side of the Arial Faith Plate, get your portals on the two single wall panels in the far end of the room.

Part 2

Player 1: Run over the Arial Faith Plate and you'll land near the door at the other side of the room.

Player 2: Once player 1 has completed 1 'lap', wait for them to hit the Faith Plate in the water (the one that leads them directly into the wall panel). As soon as they hit the plate, press the plunger to release the Companion Cube.

Player 2: You now need to get rid of all portals in the room (causing the panel to rise upwards), which in turn will allow player 1 to land safetly with the Cube.
