Player 2 : Now's your chance to get a portal on the wall ahead and then up on the alcove just above you and to your left.
Player 1 : As soon as you notice player 2 passing through the portal, raise the height of your protective barrier, so the turret can't kill your partner.
Player 1 : Follow in player 2's footsteps and get yourself up to the alcove with the Faith Plate on it. Stand on it and you too will be whisked across the chasm and onto the second part of this chamber.
Both Players: Now it's just a simple case of making a run straight for the exit and the final test chamber on this course!
