Back2Fronts is an extensive mod that will overhaul your Call of Duty 2 game to a next level. This mod brings more variety, intensity, realism and battle-like experience. Try new weapons, fight new enemies, fulfil new missions and explore new options. Mod is SP and MP friendly (although primary part is SP).
Here is a "mysterious" weapon of course made during World War II as a prototype, it could be present in the final version of the mod.
Obviously, the weapon is in WIP and does not have a skin.
PS: Let's see if someone will be able to guess what weapon is it, even if it is a bit complicated :)
