1. What you need to know:
This mod I'm working on is a mod that will, similar to the Gunslinger and Megaman, replace the Heavy's right forearm with a minigun barrel. I plan to make full first person animations and a world model with the arm replacement, however I will not make third person animations.
This is going to be a big project, I'm really unsure if I can actually do it, but I will keep this updated regularly!
Let me know if you would like to see this completed.
