Secrets
There are no official secrets in this level but you can jump without the blue key in the rocket launcher room.

Bugs
In the blue key room, if you back off the platform at the top of the stairs as it rises, it will become impossible to finish the level without the noclip cheat, as there is no way to call it back down again.

Thing 122, a spectre, is placed in a space (sector 111) which is too small for it to fit in, and is thus immobilized.
