So i was watching Pr1vate Lime, i recommend him btw, and i noticed him shove a zombie over with a shotgun and start to stomp its head in, and i asked, why cant you just bash the head of the zombie in with the butt of the gun. Now of course i dont mean pistols, but the rifles and shotguns in the game certainly have stocks long enough to bash in the heads of the undead.
I think it would be a cool animation for when you have a long gun equipped and press the stomp/shove button.
