Where the Vault Armory is
A border village on the Hajin River with checkpoints into Russia on both sides and a once-lavish casino, the Heavenly Luck, whose dark gambling floors are High threat.
The report places the Vault Armory door in Cheongun Village at grid F4: a small armory in the casino’s underground parking area. Our MW4 DMZ map marks Cheongun Village itself, not this door, because the door has not been confirmed. Our grid overlay is approximate, and some reported grids fall outside it, so trust the grid printed on the key in your backpack.
Before you go to Cheongun Village
- Cheongun Village is rated up to High threat by Activision. A duo or a careful solo run is realistic, but expect other squads drawn to the same loot.
- Bring NVGs for the casino; the floors are mostly unlit.
- Expressway No. 1, the main freeway across Hajin, runs along the south edge of the village.
