Player 1: As soon as you enter the test chamber, go to the panel on the floor to your left and set a portal here, and up on the wall to your left. You’ll now be standing on the platform up here.
Player 2 : Once player 1 is finished, fire your portals on the ground panel and the vertical wall panel to your right (it overlooks the platform where the exit door is).
Player 1: Drop through player 2’s portal below you and you’ll land on the upper platform near the exit. Now wait for player 2 to get up to the upper platform opposite. Now set a portal on the panel below them (that you fell through), and an exit portal on the vertical wall to your right.
Player 2 : Fall through and join player 1 at the exit to the first half of this test chamber.
Player 1: As soon as you enter the room, drop a portal on the floor to your left (by the platform) and then set one up on the wall beside the platform.
Player 2 : Once player 1 is up here, you need to replace the portal below with one of your own and then set an exit portal on the vertical wall panel to your upper-right.
Player 1 : Drop down and you’ll fly across to the ledge with the red switch. Walk over to it and stand on it whilst you wait for player 2 to complete their next task.
Player 2: Get yourself up onto the platform where player 1 was originally and then set a portal down below you and then on the vertical wall to your left (near the ledge where player 1 is). Fall through and you’ll land beside another red switch. Stand on it and by doing so, you’ll both release the ball from the chute. Drop it in the lock below you to open the exit!
