Since the Mod Messup page died due to unknown causes, this is basically the second link of Mod Messup. JK! It's actually it's own mod, but it's estimated to be released along with Mod Messup. Plus it's demo will also be stuffed along with the Mod Messup Demo so there will be two mods released in one!
I based this off the original TF:RE weapons. I made it as low poly as I can, because when I shot the m60, it crashed the game.
