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).
Thanks to hint from Maytckis I looked into the scripts controlling cars. The original script contained drivers still having their weapons in hands. Now it is corrected - drivers no longer have a weapon in hand during driving. They grab their weapon only after when they get out of the vehicle.
the driver no longer holds his weapon during driving.
compare with this older screenshot where you can see driver having a luger in a hand. Moddb.com
