Amazon women (pretty scantily clad) replace your fighters, and they come with wall textures (for building temples) and sounds. Pretty well done... although some of the sounds don't seem horribly appropriate for dying...

A small arena with a central area and four semicircular additions, with walls to hide behind and windows to shoot through. Small enough, and with enough big weapons, that carnage rates should be absurd, even for two players.

This puppy's much bigger than it seems at first blush. Billed as "a very simple carnage warehouse", this map contains lots and lots of nooks and crannies... enough to keep eight players busy, easily. The hill is reachable from a hundred different directions, it seems... you can jump to it from nearby ledges, and teleporters bring you to it from the farther reaches. And wonder of wonders... this map contains two lava pools, and neither one has to be fatal! This map has potential as a long-term keeper.
