Your first portal should still be connected to the bridge - walk through it, and to the end of the bridge, which should take you through a small passageway by the falling cubes. To get one of the cubes, return through your portal to the area where you entered the chamber, and, facing the gap, fire a portal onto the wall which juts into it on the left. Walk through your portal and press the button on the other side, which will cause a continuous stream of cubes to drop through a glass enclosure on the wall. Test Chamber 11įire a portal at the surface which interrupts the light bridge, then one on the wall across the gap. This time you'll bounce all the way to the third level, where you can place the cube on the button and exit the chamber. Now just grab the cube and return to the Faith Plate. Fire your other portal into the wall near the button which released the Redirection Cube, causing the laser to hit the switch across from it. Grab the first cube and go back to the Faith Plate to launch yourself back to the second level. Move the first cube out of the way, and interrupt the laser with the Redirection Cube to aim the beam at the opposite wall. Grab the cube, and drop down to the first level. Press it, and the cube will be launched over to you. On the second level, you'll find a button which releases a Discouragement Redirection Cube. Go back to the Faith Plate and launch yourself again. Use the cube to block the laser, which will lower the barrier you just flew into.

Step on the Faith Plate to launch yourself to the next level.

Fire a portal on each side of the free-standing wall, so that the laser runs through it and hits the switch. Once you've made it up to the exit, you still need to trigger the switch with the laser. Using the third angled platform, which you'll find parallel to the wall raised area which houses the exit door, repeat the Aerial Faith Plate jump again. Once you have the cube, use it to aim the laser at the free-standing wall across the way. Press it to release a Discouragement Redirection Cube on the area across from it, then repeat the jump on the second angled platform to reach it. Use the Faith Plate again to launch yourself through the angled platform and onto the raised area, where you'll find a button. Fire a portal onto the furthest angled platform - the one which is aimed at the elevated area marked with an arrow - keeping the portal you placed on the ceiling above the Faith Plate where it is. Use the Faith Plate to jump through it, then walk forward and to the left. Once she lowers the ceiling above the plate, shoot a portal onto it, and one on the horizontal strip on the ceiling ahead of you. After entering, step on the Aerial Faith Plate, and repeat for as long as GLaDOS does her thing.
