MW4 Map is a free, unofficial fan-made companion for Call of Duty: Modern Warfare 4 DMZ. Its Hajin map shows 13 major points of interest, published threat levels, an approximate tactical grid and browser-local pins. Players can look up grid cells and read linked location and progression guides. The map is a simplified schematic based on official intel; key doors, exfils and boss spawns are added only as they are confirmed. It is not affiliated with Activision or Infinity Ward.
The project gives MW4 DMZ players one browser-based reference for Hajin POIs, published threat levels and grid cells, with local pins for planning. It keeps approximate map data and unconfirmed details clearly identified rather than presenting a complete verified database.
