Same guy who did Shockadelica. This is another well-though-out level. It should keep you busy for a while..
Somebody's house, with weapons. Works only on PowerMacs.
Hard. Lots of sharp angles. Expect to start this one a bunch of times...
A very nice net level for mid-sized games. Comes with a couple of movies, to give you a feel for it...
A couple of big arenas (watch the Juggernauts!), and lots of sniper positions. A little dark.
This one's pretty slick. A two-player game (more will crash Marathon). 5-D space taken about as far as it can go. Check it out!
Short on weapons, but you can use the doors to crush your enemies... Whatever you do, don't let the Bobs out.
No real plot, just stay alive as long as possible and find all the secrets. Well made, and well thought out. Fun!
A 5-D map. Nice and clean, with some nice sniper ledges...
