Three maps. Dark Temple is just what it sounds like. (Pretty open though...) Mash Pit is a tiny arena, with a smaller hill surrounded by pfhorslime... looks like horribly high carnage rates. The Island is a Thunderdome-style map with the central area filled with water, and the hill reachable by retractable bridges.

Reminded me a lot of Spiral Insanity. An outside ring borders a mazelike multilevel building, with lots of ways to get around. A little jarring at first, but after playing it for a while, it starts to look quite nice. Best views seem to be while lying on your back in the outer ring, looking up...

A shallow, waterfilled central arena and some interconnected passageways around the outside should keep you looking over your shoulder for that next grenade...

Big weapons are in the center, behind a wall you have to walk up to to open. (Don't get trapped inside-the only way out is to blast your way past someone else coming in.)
