Circles inside of circles inside of circles inside of... Lots of staircases. A central (small) courtyard. Be sure to collect your weapons and ammo before going in... for some reason, the center doesn't seem to be big on the engine's random list. Nice looking, and very dangerous. Also available in an Evil flavor.

A simple 5D arena (or pair of arenas, to be more precise). The name comes from the orientations of the hills (which aren't actually hills, unfortunately).

A central arena with lots of twisty passageways and out-of-the-way sniper perches spread around. A nice feel to it, although some of the staircases are hard to see around.

A weaponless square ring, for two contestants to duke it out. If you leave aliens on, you'll have the added challenge of dodging fusion bolts from clueless bobs...

A single-level solo scenario. This puppy is hard. Extensive use of force-fields... pretty nicely done, overall. Don't try to blast your way through... you'll only end up dead. Look around, think about what you're doing, and above all, read the readme-it'll keep you alive more than 2 minutes. Definitely worth a look.

A mixed bag. 14 maps, generally with nice attention to detail, but sometimes with some weird angles and texture choices. You'll certainly find a number of very playable maps in this collection...

5 variations on a theme. They all center on the idea of a large arena with a floor made of platforms (hence the name), with varying degrees of complexity to the outer corridors that move around it. Nice, mostly... except that the platforms move pretty slowly, and if you're trapped in a lower corridor with the platform up, you're dead.

Converts your HUD to look like what you might see as a Pfhor soldier. Classily done, as should be expected from HAS... right down to the fonts. Deleted inexplicably from these archives... but back now. (Weird.)

A simple arena surrounded by (and intersected by) a cross-and-square built in simple 5D. Okay for small groups.
