This mod is not intended to be the best BulletTime mod out there, but IMHO, its still pretty good. I made this pretty much coz I couldnt find anything out there for UT2004 like this, Anyway, has new features and stuff, and also is compatible with most other mutators/mods. Enjoy :)
This is the bullet time 2004 mutator for unreal tournament 2004, just extract the files in your system folder en enable the mutator
