Bullets. They tear through arteries. Pulverize organs. Shatter bones.
When players lose health they limp and become slower and slower.
Yet animals, you can shoot them all day. They are either 100% alive or 100% dead. They never limp, or bleed or suffer demonstrable damage.
If I shoot a wolf in the legs with a pistol, I want to see it semi-crippled and try to retreat. I want to see bears retreat, dragging their shattered back legs behind them.
I know you can do it :-)
