Player 1: Located in the top right-hand corner by the force field there’s an angled wall panel, so place a portal here and then directly underneath the repulsion gel dispenser to your right. Press the red button and the gel will coat the floor on the left-hand side.
Player 2: Jump off of the repulsion gel – through the force field – and once you’re outside, turn to your left for the excursion funnel. Place a portal on the wall panel here and then peer down over the ledge towards the two horizontal floor platforms. You want to place a vertical excursion funnel on the platform furthest away from you.
Player 1: There’s a gap in the force field underneath the angled wall panel, so zoom across to single wall panel on the opposite wall (near the funnel) and place a portal here. Now press the red button so the funnel catches the gel.
Player 2: As soon as the gel is caught in the funnel, place the funnel somewhere else, so the gel drops right down and coats the platform below. Now look at the first platform and on the left-hand wall is a shoot-able panel. Place the horizontal funnel here so it’s just above the platform.
Player 1: Hit the red button so the closest platform is now also coated in repulsion gel, then head back to join player 2 outside. Stand on the square red button to extend the ledge over by the exit on the other side of the course.
Player 2: Take a run and jump off of the ledge down onto the first platform below, bounce across to the second platform and you should land right by the exit. Now, look down to the right and there’s a wall panel here where you need to place an excursion funnel so it’s travelling directly below you in a horizontal direction.
Player 1: It’s now your turn to jump off of the ledge and across the platforms below. Once you land in the excursion funnel, jump out onto the walkway and then join player 2 by the exit.
