Looks dead here in 2013? Shame too, would of liked to see it at least fully done. I can't download mini-patch site claims I don't have permission to view it? Still have 5.0 though. Be nice to see the unique music in it released under a Creative Commons thing (Non-Commercial of course :P ). jamendo (com) would be a good place to for it.
Edit: Another idea, could instead do a entire game around AR2? Could be open-source and could use warzone2100 and work off it.
