Either way I propose a High five! *Raises hand*
hows about if you want to kill them while their down you can hold X or just tap it just tapping would make a quick animation and the hold would be a slower one, i think that the cole one someguy mentioned as kinda bad becasue kicking the headaway would be annoying as hell. i would prefer if cole could just soccer kick them in the face, and i think a customizable character would be cool like, choosing the animation or whatever
I seriously like the idea, I don't know why everyone is so worried about not being able to quick melee a downed opponet, it is called shooting them at point black, same difference.
