As far as I can tell, the game produces no sound when a vehicle collides with an object. For instance, if I drive a Hunter at full speed into a wall, I stop violently, see some bits fly off of the front of my vehicle... and that is it. There is no noise. There isn't even the horrific metallic crunch that Arma 2 had. Is this as planned? That is, is this a feature which simply has yet to be added to the vehicles, or is this a mistake?
