I was thinking, with explosions in mind. If you were in the centre of the explosion you would die, a bit off the centre, you could lose your legs and be stuck crawling, if you were just by the explosion you would be knocked back.
If not that, could someone make an add-on when you fall and die realistically, like when you kill a mutalid, they don't fall on their backs, they fall and are animated when they hit the floor, such as their hands and feet spreading.
