What it does is making the civilians scream randomly, crazy, i know.
This mod was made just as a test to learn lua better, Idk anyone who would use smt like this
If u want to change the percentage chance of them screaming go to mod.lua, on line 2 change the 0.015 to whatever amount you want (note that the percentage is ran every frame)
For example:
if u change it to 1 = 100% chance of a civilian screaming every frame
if u change it to 0.5 = 50% chance of a civilian screaming every frame
