Player 2: You need to be constantly ready to respond to player 1’s situation by standing on or off the red button on the floor, this’ll redirect the flow of the funnel (so to make your life that little bit easier, zoom in with your portal gun to keep a closer eye on your team mate).
Player 1: You’ll next find yourself in another vertical part of the course with another spiked crusher coming from left to right halfway up. So get a portal below you so you’re ascending upwards and if you think the spikes are going to come across as you’re going up, ask player 2 to step on the button to bring you down a bit. As soon as you pass the trap, look straight ahead for the arrows pointing to the wall panel in the distance.
