It's a totally new weapon pack for the old Unreal Tournament, which has 14 totally new weapons, a total new gameplay, between other features.
This is the new version uz file, for server redirect, to avoid big times downloading a pack uncompressed and directly from the game hosting server.
Nice! Is this going to have a umod file? :)
Maybe. This version won't get the umod (too late now), but the final version might have one. I will still think about and check how to do that.
