A loving renovation of Mars Needs Women. This one's better than the original, I think... the only criticism I have (and it's really minor) is that the upstairs may not be dark enough any more. Other than that, though... This is gorgeous.
Once again proving that Waldo World was Bungie's most popular M1 net level, here's another version of that beautiful arena. This one's outdoors, and sports M2 niceties such as vistas, whistling winds, and shootable lights. Oh, yeah, and a shotgun...
This is Axiocranium with a twist. Map's the same, but there are lots and lots and lots of bobs, and with the enclosed physics model, some of them don't like you very much... You've got to figure out which ones. Nicely frenetic. Contains the original Axiocranium (v2), also.
Geometrical battlefield (designed for teams, but playable without them). Has an invisible wall bug that makes it impossible to get to one of the chargers. (I was unable to fix it.) Author says it's unfinished. (Still plays okay, except for the wall bug...)
