zombielore

zombie_lore.lua — Zombie module

What it does

Dynamically rewrites the active SandboxVars.ZombieLore settings and immediately forces all nearby zombies to recalculate their stats. Supports named preset profiles, full manual stat overrides, a randomise flag, a stress-scaling mode, sprinter percentage control, and an optional persistent auto-mutation system (ShavedChalupa).
