Player 1: Look for the red laser that’s located in the distance and just south of it is a slanted wall panel, place your first portal here and then rest your second portal directly under the propulsion gel dispenser. Press the button twice and it’ll coat the angled platform in the middle of the room.

Player 2: Once the platform is fully coated, use your portals to get over here and then stand there ready for player 1’s impending countdown.

Player 1: Stand near the red button and look straight ahead, in the distance you should notice a panel with a red arrow pointing down (near the water). Replace the portal from the dispenser here and stand by the red button now.

For the next few steps you need to be really quick if you’re going to make it (it’s easy to mess this up as you’ll see if you watch our video). So initiate a countdown timer and as soon as it reaches ‘2’, tell player 2 to start running and hit the red button to release the Displacement Cube into the portals. If you’ve timed it right, player 2 will catch the crate in mid-air as they hurtle towards the portal the Displacement Cube came out of.

Now you need to be especially quick here, once your colleague has caught the Cube, look down at the water for the two square panels. You want to place an exit portal on either of the two panels, this will cause player 2 to sail straight up to the red laser beam.

Player 2: Your task is to aim the Cube at the set of turrets directly ahead of you, so the beam is deflected, setting them all on fire!

Player 1: Before player 2 descends back into the portal they came out of, place a second portal on the other square panel so your friend sails up to the laser beam again, allowing them to redirect the laser beam into the second set of turrets. Your next task is to turn to your left and look for the angled wall panel up above you and place an exit portal here. If you’ve timed it right (unlike me in our video), your teammate will soar across to the exit door. Once they have, get yourself over to the long angled platform covered in the orange propulsion gel and dash across the ramp towards the angled wall panel ahead.

Player 2: Your task is to set a portal on the wall player 1 is about to plough into and another one on the angled wall panel that you last came shooting out of. Do it right and player 1 will join you at the exit.
