This is a very simple mod that makes it possible to change headshot damage multiplier resulting in faster kills or “one shot” headshot.
Multiplier can be configured from the code by editing variable headshotMultiplier.
Defaults to 5x damage for headshots which is almost always a one shot kill depending on weapon type and range (in normal not hardcore). Do note that raising this over 5 makes shotguns quite overpowered.
