How do I make NPCs get knocked back when I kill them?

Whenever I shoot an NPC and kill it, it always just slops down instead of being knocked back a few feet. Same thing happens with RPGs, gravity guns, SMGs, shotguns, and more. Any way to make NPCs get knocked back when being killed?

As far as I know there is no way to do this built into the game. However if you are doing this for a game mode you could create a point push entity in front of the npc when it’s death hooks are called. Or something of that nature. It would force it to fly back depending on the strength of the entity. If you can’t do it you could post in the lua section for information on achieving this.

Turn phys_pushscale up.

This worked, thanks.
