3rd time YoSoyProzac. Do research before you open your mouth about another mod idea. You can't port animations yet and biggest chances it will never happen at this rate. Sure some guns that fit with the animation can use it but that would be it. Anything else is impossible. Also, learn what can and can't be done when it comes to Payday 2 mods. This isn't L4D2 or any source game so it's already in a hard spot as is.
