Helmets never loss
This mod needs to be loaded last.
I’ve only tested it on the original game. Using it with other mods may produce unexpected things.
If you want to use it on other mods
open it: your mod directory/resource/gamelogic.pak/set/interaction_entity OR resourcesetinteraction_entity
find and edit human.inc
search for this: take_off "head"
Replace it with: bullet_detonate. AND Delete {impulse up 5 2 dir 7 3}
OR modify "if rand 0.05" to "if rand 0.0005"
save and start game.
