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).
Russians now have uniforms without the snow in the early Stalingrad mission (so before the whole Stalingrad was covered in snow).
Also note that subtitles were added to all custom maps - so if you want to play with true Russian language you will know what the AI is saying.
