Mark Rein :
We’re getting pretty close to releasing the Unreal Tournament 3 Beta Demo for Windows. The Beta Demo will allow instant action play against bots as well as online multiplayer.
The purpose of the Beta Demo is to test the game on a large variety of hardware configurations and get gameplay feedback from the community. The development team feels they’re pretty close to being ready to release this so it could come out this week but for safety sake I’d say it should be out within two weeks.
