1.Test Chamber 11 Start Point
2.Test Chamber 11 End Point
Test Chamber 11 looks a little intimidating at first. The first thing you notice is the orange portal gun fixed to a rotating arm in the chamber below you, mounted on a platform that’s surrounded by toxic goo. It will soon be yours! First, place a blue portal on the wall to your right. Cross into it only when you can see firm ground on the other end—since the orange portal gun is on a rotating arm, you may have to wait until it does a full cycle. You’re looking for a room with a red switch.
When you see the switch, hop through, hit the switch, and fire a blue portal on the surface behind the panel that just retracted above you on the far end of the room. You should still have time to back out of the orange portal, but if not, just wait until it cycles to your position again.
You’ve just entered a room with a series of stairs and a Ball Launcher at the far end wall to the left of where you emerged. Stand directly below the Launcher, and give yourself a good vantage point through the glass wall. You must to see the direction that the orange portal gun is facing, as well as the Ball Catcher on the opposite end of the chamber beyond the glass wall. When the orange portal gun is aiming in the opposite direction from the Catcher, place a blue portal on the point where the energy ball makes contact with the wall in the room you’re in‚ again, look for the charred spot. The ball goes through the blue portal into the Catcher in the next room and activates the horizontal lift. Wait for orange portal gun to place a portal near the newly activated lift’s destination on the far wall, then walk onto it.
The lift ferries you to your prize—the orange portal gun! Snatch it, and activate the switch just ahead of it. Fire an orange portal behind the retracted panel, and wait for the lift to come back. Once it takes you back to the wall, fire a blue portal, walk through, and proceed to the exit. Well done! You are now in possession of the fully realized Aperture Science Handheld Portal Device! You no longer need to be beholden to arbitrarily deployed orange portals. The power to fully distort spatial dimensions is now in your hands!
