Good graphics, bad voices
However good the animation is, I just don't get the feeling of ass-kicking potetional when I am supposed to believe that the owners of the voices (don't feel bad, most actors have voice manipulation done too) are supposed to be the ones shooting these guns.
Sheesh, at least take a basic wav editor (cool edit comes to mind, it totaly rocks!) and manipulate the voices some to give them that "evil killer" edge that they need.
