Ive recently installed the sound enhancement mod for MW, and i have to say, it really enhances the immersion!
when you look at the OB trailer, and view the part of the skeleton walking past the camera, please listen to the sounds. do you think that sounds good? i think, the sounds of the skeleton ... well suck.
i really hope beth has learned from the errors of the past, since most of the sounds in MW suck too, and will use better sounds this time.
(same goes for animations actually - what we can see right now is not all too good.)
