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).

This map just about maxes out object limits in Marathon, and because of this is horribly slow on anything but a powermac (and even then...) Otherwise, it's a pretty straightforward map with lots and lots and lots and lots of ammo and baddies and stuff.

The first two levels of a rather large scenario. (All the levels are there, but only the first two have polygons in them... well, the third has a pair so that you can teleport in, but...) Generally pretty difficult, but more for techical reasons than anything else. The central shaft on the first level (by which most intra-level travel occurs) is a bit tough to get the hang of. Once you've figured it out (and ignored the bad textures inside), it's pretty cool... and there's a nice trap on level two.

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.

3 maps (ports of the maps in Suicide 25). A good batch, but very open-really slow on slower machines.

3 maps, all original. Spanish Magic Castle is a lot of fun, but watch folks who guard rechargers...

Another port of a Kendall Redburn M1 map. This one's square, with all flow in one direction (clockwise). Makes for dicey spanker shooting (you're often in narrow walkway spaces).

A three-level solo scenario where the bobs are your enemies, and everything else (well, almost everything) is on your side. (Comes with a physics model to make it work.) Well-planned levels take advantage of situations where bobs are superior, fighting-wise... pretty difficult, even on Normal.
