Portal 2 Hints
How can I get a storage cube to the exit door?
1 of 12: There's no direct path connecting the cube alcove to the exit door's alcove, but there is a moving platform that goes back and forth between the two alcoves.
2 of 12: That is, it'll go back and forth if it's receiving power.
3 of 12: Return to the chamber's starting platform and visually follow the line of blue dots that starts near the platform to find the laser receptacle that powers it.
4 of 12: You now need to redirect the laser beam into the receptacle.
5 of 12: The beam is hitting a portal-friendly wall, and the wall that's directly across the room from the receptacle is also portal-friendly, so it should be clear what you need to do.
6 of 12: Put a blue portal on the wall that the laser is hitting, then put an orange portal on the wall that's directly across from the receptacle. (Make sure you're out of the laser's path before you place the orange portal.)
7 of 12: That'll get the platform moving, but now you need to get back across to the storage cube alcove.
8 of 12: Put the blue portal back to where the laser beam will go through it, then pick up the storage cube and get ready to jump onto the platform with it.
9 of 12: Or wait until the platform gets close, then move the blue portal so the platform will stop. It'll then be easier to jump onto than if it was moving. Once you and the cube are on it, move the blue portal back to where the laser can go through it.
10 of 12: Since the platform goes right under the laser beam, you'll need to hold the cube up high to prevent it from blocking the beam, then jump over the beam to keep it from knocking you off the platform.
11 of 12: Or hold the cube low so that it blocks the beam and stops the platform, edge around to where you're on the side of the platform that's past the laser beam, then raise the cube up so that the platform will start moving again.
12 of 12: When the platform gets close to the exit door's alcove, jump over to it and drop the cube on the big red button so you can leave.
