All Secret Bunker locations in Modern Warfare 4 DMZ

Modern Warfare 4 DMZ has one secret bunker on the Hajin map, tucked near the Political Prison point of interest. It is not marked on the map, so players can miss it, but reaching its locked inner room can reward them with valuable loot.

The bunker is in the north-western part of the map, and its entrance door needs no code. Inside, follow the main hallway to a locked door; a key can be found in one of the nearby rooms, though its location varies. A separate silo room is also locked, while the surrounding rooms contain useful resources.
