So, after many hours of reversing CA's classes, I now have complete control over a gun's animation, allowing me to basically hex edit the gun in game.
This video shows some of the REZ hacks I've implemented so far: rapid fire, no reload, and instant draw. I'll remove the pre-fire later.

Just felt like sharing that whatever can be done with modding can also be done with hacks.
