Once player 2 has landed by the entrance to part 3, drop down into the portal on the slanted wall panel and you'll land on the Arial Faith Plate, sending you up to player 2 and the final part of this test chamber.
Player 1: Once more you need to get a portal over the Arial Faith Plate and then on the slanted panel in the top left-hand corner of the room. Hit the Plate and you'll soar over to the red floor button behind the force field.
Player 2: Set a portal on the horizontal panel opposite the force field and use the Arial Faith Plate to boost across to the platform behind the force field. Now set both of your portals on the two panels in here (now STAY here)!
