Okay, so this is an odd thought, and really quite unimportant in the scheme of the game, but I have to say it;
I love it when we chop the heads off enemies, but isn’t it kinda odd how you can slice them vertically through the head and their head separates at the neck? 
Someday I would hope to see heads be able to stay on from that kind of strike, or even split in half. Hell, if you could bisect an enemy from a vertical slice, that’d be amazing . . .
