The bar isn't that high; I've already got rigged models for the weapons in-production (the M911A1, MPs, etc), + models for their ammunition. The only thing holding me back at the moment is animations (I don't know how to do those in the least) and more modding support from OldSnake; currently there is no easy method to view and modify spawn-rates and add new items to the game because the code is trapped inside the core architecture, rather than available to view and do.
When I finish these, I hope to add a MAS49/56. I feel like it's a nice survival rifle (a semi-auto M1 Garand-like that fought in Vietnam) and I owe the game dev a few Frog guns. The model will most likely come from another member of the forums I've contacted for help, but as far as I know it will lack animations/anything.
