MW4 Map

Enter D7 in MW4 Map and the Hajin map highlights that grid cell. The linked official Call of Duty guide uses D7 for Imjin Farmland. For a player reading a key's grid reference, this gives the coordinate a place on a map before looking for the door itself.

The map shows 13 major points of interest, with layers for named places, threat zones and the tactical grid. Its location table lists the highest published threat rating within each major area, with more detail available through the linked location guides.

The coastline, rivers and positions are simplified, and the grid is approximate. At the October 20, 2026 check, the site said key doors, extraction points and boss spawns would be added as they were confirmed. A grid reference narrows an area; it does not establish the exact position of an unconfirmed door.

The site offers personal map pins. Its privacy notice says these stay in local browser storage and disappear when that data is cleared. That makes them reminders for the browser you are using, without an account to carry them to another device.

The site is free to browse. Its privacy notice also describes website analytics and Cloudflare and Discord requests. Grid lookup was checked in the public browser page; pin retention and the map's in-game accuracy were not tested.
