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).
CoD2 has some strange aspects in sound system for weapons. Some static weapons have only loop sounds enabled, some only single and some both. As a result, some weapons that are same in external appearance, use different sounds (30cal, Flakvierling). I managed to correct that issue.
