Where is test chamber 10

The third room is much like the second room, but this time the orange portal is placed at the bottom of the room's pit. Look overhead and watch as a couple of wall panels push out to overhang the pit. Fire a blue portal onto the top of the wall panel and then jump off the ledge into the orange portal below. You'll be catapulted to the next level, but you're still not done.

You need to climb another level via a momentum jump. The wall panel should again push forward, closer toward the gap. Again, launch a blue portal onto the very top of this wall panel. One issue is that the discouragement redirection cube sometimes falls down after it's launched. That's why I paused and waited to see what it does. Sorry about the sound. I'm not sure what happened.

I forgot to add that this was a great method. Posted by Killipo on 26 Aug 11 at Thanks for this method. Worked for me. I could not get it using the other method. Posted by SighKo on 30 Sep 11 at Worked for me on my 5th try or so in the Ricochet challenge level, of course this is after not having played the game for a few months.

There are two easy placs to screw up: shooting the blue shortcut portal make sure the orange one you peek out of turns blue signaling you're out far enough before you shoot and the drop for the deflecting cube it sometimes does not land on the ledge and you need to carry it up. I also saw some glitchy behavior picking up the weighted cube.

Look up and to the right, and you should see a white patch of ceiling tiles. Place a blue portal on this ceiling, then look down over the edge in front of you. Fire an orange portal onto the floor down here and jump in. You should land on a staircase underneath the blue portal.

Head up these stairs and through the material emancipation grill. Take an immediate left and peer over the edge, down at the lower level. Fire a green portal onto the white rectangle, directly below the blue wiring on the wall. This will lower the glass wall in your way. Drop back down to the main part of the room and step on the aerial faith plate again.

This time, you will hit some aerial faith plates on the wall and get bounced up to a higher part of the room. There is a laser receiver here, and a portal wall across from it. Additionally, there is a small red button that will drop a laser redirection cube from the cube chute. Before pressing the red button, shoot a portal into the wall facing the laser receiver.

Then press the button.
