Ballistic Weapons replaces UT2004's wepaons with a batch of new, realistic, high quality weapons using an enhanced weapons sytem with reloading, aiming, firemodes, improved damage behaviour and much more to give the game a more tactical style. All the items have also been replaced and the mod uses totally original sounds and effects. The entire mod is implemented through a mutator so it is compatible with all gametypes and many different mods. It also comes with a melee mutator to play using only the melee weapons. Decent bot support has been included, allowing the bots to use all the new weapons. The mod has also been designed to be very mod friendly so as to serve as a base for other mods allowing most features and systems to be implemented using just the default properties of new weapons. A manual is included with the mod as well.
Ballistic Weapons is a must have. It's a perfect conception of new weapons in Unreal Tournament, changing the gameplay in a subtle way while still giving it an absolute make-over in terms of the arsenal. I rarely play Vanilla UT any more, THAT is how good this is.
