Basically, no tree branches or bushes make any sort of rustling sound when you walk/run through them. Every other game I've played recently does have this sound, and I've never thought of it being an issue before, until I came to this game. I could tell something wasn't right after about 5 mins of playing this game for the first time. It really would add to the immersion of the game if a little more detail was given to the sound design.
