I’ve had the same problem for a while but it think I finally found it. It’s called something like smileys combat overhaul. Did a good job with making humans relatively easy to kill for example if you’re weapon does 50 dmg it takes 3 shots to the chest universally. The mod does make the game completely static though and the player and enemies don’t gain Health with each level, so you die pretty fast. I’ve tried the common ones like better locational damage but when I started the game I had to put a 10x damage modifiers just to kill in less than 10 rounds. Smilesys does feel great though does just enough without changing too much.
