I love the chicks, but about the minigun animation. well +A for effort but there's alot of flaws in it..
For starters, this might sound sick but i love the vanilla animation for the minigun. As the PC buckels up before starting to fire the minigun, that looks realistic, now i know a minigun would have quite a woolop of a recoil, but flying that far back? that seems strange.
I recommend, dont know about everybody else in here, but i recommend that you dont change to much of the vanilla animation, as he dosent fire a big burst of bullets with the minigun, he should be starting the animation like vanilla, but after he fired the minigun it should look like he abort the fire becuase the recoil strain to much, and as such at the end of the "firing season" he should take his right leg, one step backwards.. release some tension on the minigun by pointing it downward, and then continue to take the same leg, step forward, and return the minigun to the current idle position. thats just my recomendation.
