🎯 What It Does

This mod creates **intelligent spawn zones** across your map that activate when players get close. Each zone can have multiple spawn points with different entity types, spawn chances, and behaviors. Perfect for:

Military zones with elite zombies
Underground bunkers with precise positioning
Wildlife areas with predator packs
Urban hordes in cities
Boss encounters at POIs
Dynamic events anywhere on the map
