This is a weapons mod that i spent about 2 months on, adds about 10 new weapons. The mutator modifies every ones speed and health as well, and i added some new health pickups and things. Every gun uses the same ammo, just different guns use more or less ammo depending on damage or usefulness. Also the weapon models may look weird because I use the SDK render device when i play, which stops gun models from showing the missing parts.
this should hopefully fix the problems with online play and a few balancing issues aswell, you wont need the previous version of the mod for this to work, just extract to the System folder and play
