Guess what, I did it
Well, sort of; I never had the time to make the tank, only added a lighter version of the weapon (similar to Warboy's) and used Dioxine's sprites for the real deal. The Minigun 1.1 mod is in the initial post.
I want to make a better sprite for the light minigun later. For now, please use the old one, since I believe in frequent updates.
When installing, remember to remove the entire Resources/Minigun folder first, as the new files often have different names.
Another version coming soon!
EDIT: Added the tank! Everything's functional, and available for download in the first post.
Next thing, I need to work on visual improvements.
