To get to the surveillance rooms in the middle of this complex, you have to use
the corpse disposal chutes in the cells. However, on the 1st and 2nd floors,
these cells are locked. That's so the kids wouldn't discover them.
So you have to get to the 1st floor from one of the cells on the 3rd floor. I know
how to do it, but it's really a pain. Also, the lights only work on the 3rd floor.
