5 levels. Mostly simple, with no place to hide-geometrical. Good for carnage... The title map is somewhat more complicated.
Lots of very long, very narrow passageways, and no real ammo. Comes with a physics model. Impossible without it (the hunters will take you down very quickly), but way too easy with it...
A very nicely done novelty map. C'mon, download it, it's tiny! (It was out on Christmas eve, sorry I didn't get it up quickly...)
A really simple 5D map. So simple, in fact, you may have trouble finding the 5D space... until your fodder is in it.
Dark. The better weapons are hidden...
