As the title says. I’ve noticed many times I’ve shot a chaff/traitor guardsman enemy in the head/smacked them in melee and watched them stand upright seemingly alright for several seconds before falling over. In the mayhem of a horde, or when you’re trying to pick off enemies, this can cause you to waste time swinging a melee weapon or ammo shooting. a wasteful doubletap.
As such, I really think that sort of animation (weakspot kills specifically?) that gives very clear visual feedback they’re dead. While ragdolling like a half-life 2 metro cop would be hilarious, I would be happy with them simply falling over far faster.
