Player 2: Once the two of you reach the wall, look behind you and low down is a shoot-able area of wall. Get your funnel coming out of here so it carries you towards the force field in the distance.
Player 1: There’s a second small rectangular wall panel just up past the first one, if you shoot this, it’ll provide greater cover against the turrets as you approach the force field. Once you both hit it, you’ll fall down to the platform below, head through to the second part of this test.
Player 2: Your task is to control the excursion funnel, so get a portal on the funnel and then on the chequered floor tile near the corner. You now need to ask player 1 to jump into the vertical funnel first and you need to follow afterwards.
