90%/100%/100% in 6:41 (+saves?) on UV.

For some reason it felt kind of weird having really big open rooms, but the architecture was slightly interesting nonetheless. I basically ran out of ammo by the big final room (like 60 cell ammo only) so I had to cheese my way through it -- I hid in the area with the single rocket, chainsawed the enemies that funneled in, and let the other monsters kill each other through in-fighting, and then I just rushed for the exit.

Glitchy and broken.
I was only able to get out of the first room by "cheating" (using Zdoom's jump feature).

Yeah, I messed up on this one unfortunately. Sorry dudes.
