After months of hard work, Unreal DooM (UDooM, for short) for Unreal Tournament, is released as Beta Version 1! You can find it here.
Mixing updated technology with old concepts, UDooM seeks to combine the aspects of multiplayer DooM (and maybe single-player DooM, later) with the Unreal Tournament engine, resulting in smoother flow with kick-ass weapons and extreme mayhem!
Because of the open-ended project formation, anybody can contribute to UDooM. See the mod profile for more information on contribution.
