Very simple map. (Comes in two versions-one for two-person net play, one for solo play.) Basically, it's very similar to Evan Vetere's Joust- each player tries to knock the other off his platform into the lava below. Solo version substitutes a trooper for your net opponent.

A pretty straightforward arena, with a small tower in the center. (It's not set up for KOH, but if it were, the hill would be pretty difficult to reach. There are other reasons to go up there, though...) Comes in two versions (with and without aliens), and with a physics model to make the aliens less nasty.

A pretty standard arena, with some pillars which can be used as vantage points. Really slow on 68K macs (probably because it's so open), and the lack of texture alignment is jarring.

Very big, with two distinct sections. There's an outdoor arena with some connecting passages for multiple entry points, and an indoor set of corridors that give you lots of corners to hide behind. A bit slow on 68K machines...

Made with the flow concepts of Bungie's What Goes Up in mind. Pretty nice flow. Contains a pretty superflous crusher (docs say it's for the player who likes to hide in small rooms and shoot people who come in (I guess like the spanker room in What Goes Up), but who'd go into it after the first time?). Update adds a bunch of new features (new stairwell, a window, some minor tweaks).

Inspired by Everyone's Mortal But Me. Look around for the invincibility...

This is easily the best KOH level I've ever seen. Wow, I don't think I've ever said anything like that before... Check it out. This map is good.

Several small, interconnected rooms. Sniper positions tend to be below a level, rather than above... pretty fun. 1.1 update added quite a bit of new space (including an out-of-the-way arena), and changed the alien balance. 1.3 update aligns textures, adds lots of water, and seems to decrease total alien population. This is no longer a small map.

A small, circular arena, a remake of a Kendall Redburn M1 map. It was a nice map to start with, and this version keeps the gameplay of the first one while upgrading the look.
