Drop-Catch. For those of you who didn't read the basics section, first
hang from the railing above that one, then press X to let go, then press Y
again just as you hit the next railing. Once you're in this secret area,
you may notice the two pipes on the wall. One's liquid nitrogen, the other's
steam. Shoot them while holding the KEY, and it will automatically change
color. You have to Hang-Drop-Catch again to leave, by grabbing onto the
wire at the bottom, so be careful. However, if you prefer the simpler
method, just head out to the Warehouse.
