I remember spending hours playing UT2004 back in the day. There was supposed to be a new version a few years ago but it never really made it. Really hoping in the future a company tries to raise it from the dead.
Maybe UT will comeback for the new Unreal engine 4, but since military style FPS are all the rage now... dunno if there is a place for a non military FPS in these days. Sci-Fi FPS games like Quake and UT didn't get new versions from a long time.
