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 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 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.
