A large, (technically) symmetrical level, with open, well-lit spaces, dark rooms, and some tight maze areas. Good for bigger groups.

5 levels. Very large, generally quite playable. Lots of symmetry, as well as a bit of carelessness (bad textures in places you don't go very often, etc). A couple are very pretty to look at, and a couple seem to use textures gratuitously (that is, there are texture changes that seem to be nothing more than an attempt to get another texture in).

11 pretty big maps. Generally very well-constructed, but using a huge variety of textures per map (adds to eye fatigue after a while). Flow is usually pretty good, and textures are nicely aligned. Worth a look if you have a group of 4 or more.

A pretty straightforward port of Mars Needs Women. Nice job, overall... The only additions are small, to take advantage of some of the improvements of the M2 engine. The intention was to create an M2 version that stayed truer to the original than most of the existing ports, both in feel and in playability. In that, it is a success.

A symmetrical map using water cannons for rapid movement. Clean, and easy to get the hang of... very fast-paced carnage.

One side is full of canyons and ledges, the other side is a fortress. Between them is a lava river that serves more than one purpose. This map is really pretty to look at, but if you play it with aliens on, you'll never get to see that... A little bit of smearing at the bottommost corridor, where the lava comes up too high, but nothing major.

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...
