yes, in shooting/killing someone white target = unable to move, knocked out. black = dead.
the white eventually fades to grey then black sometimes or they go back to orange or something and they somehow get away. in white they are either in a siesure, moving around but not standing up because you shot them in the leg or they are in too much pain, knocked out is just moving slightly, like fear. Black is just dead.
I think limbs and stuff will have real reactions, gib, blown off, ripped to pieces but still connected, ripped off, chopped off. stuff like that.
