12 maps. Lots of (too) sharp angles, and some jarring texture choices, but there's some pretty nice use of platforms here...

A pretty simple maze, with a somewhat hard-to-find center room. (Much easier if you're not playing this networked... more time.) Nasty Minotaur... but he's not too bad to kill, the first time.

Lots and lots of twisty passageways, leading into monster-filled rooms. I'd recommend turning aliens off for netplay... or you're going to have a hard time finding your human opponents.

Another very pretty map from Dr. Mace. The center platform thing doesn't seem to be horribly useful (more for show than anything else), but other than that, this looks to be a fast-paced map.
