Weaponized Cow Gun
Using protato's mod maker (https://videogamemods.com/justcause4/mods/protatos-mod-creator-v05/) I made the cow gun have similar stats to the SMG.
So now you can kill your enemies but they have turned into mutant cows..
if you guys want me to I could make different versions (burst fire, OP, air cannon, etc) of the gun.
