NIce idea. Might I suggest renaming it though?Wild_qwerty said:Mini Shotgun
"Mini Shotgun" sounds like it's a smaller version of a standard shotgun - perhaps a pistol sized version. I can't really think of a generic name, but given that most of the FO2 miniguns had other names (ie. not "Mini 4.7mm Caselessgun" ) I would suggest "Perforator Minigun" or maybe "Perforator 12 gauge Minigun".
Also, if you are looking for more weapon animations, you may want to re-work some of the FO2 character models to use more of the weapon animations (for instance, I believe the "Male Tribal" (Sulik type) can only use 4, not including HtH). Expanding this would obviously give you a few more options for NPCs and encounters.
