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.

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.

Interconnected passageways and a small pool with goodies in it. The door controls introduce some nice flow oddities. Comes with a physics model that allows bullets and grenades to penetrate water.
