Player 1: Once you start the latest chamber, hang a right and proceed through the force field, now look up at the wall panel (up above the red button) and set your first portal here. Now edge forwards and to the right a bit so you spot the vertical wall panel closest to the back of the room. Get your second portal here and now stand on the red button beside you to trigger the excursion funnel (that’ll also now appear in the middle of the room).
Player 2: Once the portal is flowing through the middle section of the chamber, stand on the Arial Faith plate to catapult yourself over to the other side. Once you’re here, fire your first portal on the second vertical panel in the middle of the room and then the next one on the horizontal floor tile located to the right of the panel you just placed last portal on. This’ll create a funnel that’ll travel vertical towards the exit. Now stand on the nearby Faith Plate and as you ascend the funnel, the force field above you will cut you off, causing you to drop down. Ask player 1 to stand on the red button, causing the funnel to reverse in direction, once the beam is orange, jump across into the beam and look out for the other platform located off to the side just up ahead, step out of the beam onto this platform with a red button on it.
Player 1: Walk back out into the main area of the chamber and look up at the far wall at the other end, there will now be an area available that you can set a portal on. Now look to your left and where player 2 had the vertical funnel, set your exit portal on this very same horizontal panel. Step on the Arial Faith Plate and you’ll find yourself soaring up through the force field above you.
Once you’re safely on the upper level, move off the ledge and walk over to the top-left corner of the area and you’ll be overlooking the excursion funnel device below. Set a portal back on the wall where the funnel hits and then peer over the ledge that overlooks the main area. Reset a portal back on the vertical panel that’s beside player 2 (to create a funnel taking them back over to the ledge underneath the force field). Once they’re there, set an exit portal underneath them so the funnel carries them up towards the exit.
