Hey, so I saw this a long time ago, and this looks ♥♥♥♥♥♥♥ rad. I'm still hoping that you would see this and hope that you are still working on this. But I was thinking. Why not have it as a primary? In my opinion, it would make sense. It would look too OP as a secondary with the minigun. But replacing the minigun, with a high-powered, large calibre, huge, ass Magnum. It can work as a mingun aswell (sorta). When you have the Heavy Caliber equiped, but not in a firing position, you would hold the muzzle facing up. (Like some of the pictures shown.) And have it ready to fire at a firing position. (You get the idea.)

I hope that the author sees this and gets some sort of inspiration out of it. If not, then better luck next time? But anyways, If you do though. I believe that this will make the heavy be loved alot more right now and it would make a really interesting play-style. Thanky you, and Goodluck!!!
