In case anyone is interested in the early Nexuiz dev I've uploaded some very old builds:
http://www.alientrap.org/verm/20031104.zip - November 2003, at least has some Quake3 like maps, most of the weapon models, and is somewhat playable
http://www.alientrap.org/verm/embarrassingly_bad_nexuiz.zip- The name says it all, this is the earliest Nexuiz build I have now. All half life maps, weapons and movement are just horrible and incredibly stupid, models are insanely large... but have fun
And you can check out the old Nexuiz trailer here:
