The one problem is that it now has only one main developer (divverent) and about three part time contributors. Div has alot of pressure on him and needs help. As it is now he does both most of the quake C additions and the engine adaptions. Nexuiz needs more quake C and normal C coders (and could use a modler, animator, and all that jazz too). I myself make about one map per month or two for nexuiz (I've made 24 so far) but I can't code in either of the languages (I'm a perl coder) and it's difficult for me to wrap my head around quake C as it's so diffrent for me. I also make some (GPL) music from time to time so I guess I'm more of an "artist" than anything else. Anyway, this is a pretty advanced game as far as opensource releases go, I was wondering if you or anyone you know of could lend a hand.
Note: Their website is Nexuiz.com and http://www.sf.net/projects/nexuiz . There are some videos, download packages (including source in the zip), and a forum. The game runs on linux, windows, and mac (and recently div ported gtkradiant to the make system and removed unneeded dependancies so that will be able to be ported everywhere too).
