Hey was just browsing the net in general looking for a decent 2d engine for a chrono make and i stumlbed on this:
Steve Massey's UT2004 mod "Greed"This is basiclly a UT2004 Mod. It has a lot of work put into it and I think that the people who made it would be worthy additions to CT:RP. I personally like what i see there.
PS. It mentions that he only did the technical work but perhaps you can get a hold of the artists.
