The problem I'm having is that the headshot hitbox on halo 4 is SO much different than reach. It seems as though anything below the nose on spartans is not considered a headshot while the bottom of the crosshair can barley be skimming the crown of the head; which, Im sure, most people would consider a miss, and that is still a headshot. But as far as the kill cams go, I think they are some times just ****** up. 343 has some work to do with those
