Player 1: Immediately upon enter the test chamber properly, take a left and you should spot the light bridge. Get a portal on the wall here and then get your second portal on the left-most panel located just under the ‘EXIT’ writing painted on the wall in the distance, creating a bridge extending all the way across.

Player 2: Join player 1 on the light bridge and once you’re in line with the red button (located to your right), you need to set a portal on the end of the light bridge and then on the left-hand wall so the bridge crosses over right to the red button.

Player 1: Press the red button and – as long as you placed your light bridge correctly – repulsion gel will land on the bridge, allowing you both to jump up to the other side and onto part 2 of the chamber.

Part 2

Player 1: Once you’re standing on the light bridge, turn left and at the bottom, set a portal on both of the wall panels down here. This’ll allow player 2 to traverse to the other side, past the force field. In preparation, stand right beside the red button, getting ready to press it.

Player 2: Run down the light bridge and set your portals on the two wall panels in the corner of the room. Once the two light bridges are ready, let your teammate know.

Player 1: Press the red button to release the repulsion gel onto player 2’s light bridge. Instruct them to jump off of it, onto the ledge ahead.

Player 2: Once you’re on the ledge, turn back around and place a portal on the single wall panel located directly below the repulsion gel dispenser. Now run back around to where your buddy is and look for the single horizontal wall panel that’s hanging down above the main light bridge. Get a portal on this and ask player 1 to press the red button again.

Player 1: With the light bridge now coated in the gel, use it to jump up to the ledge with player 2 and make your way to the exit.
