Chang-san Air Base is built directly into a granite hillside in western Hajin — officially the westernmost point of the map. The surface level is rated Critical: missile bunkers, a toxic chemical containment pool, a hospital, helipad, runway, barracks and supply depots, all defended.
The real prize is underground. A vast bunker complex — larger than the surface footprint — was carved into the rock, and ground-penetrating radar scans suggest buried tunnels still undiscovered. The Air Base Bunker is rated Extreme, one of only two such areas on the map. The Admin Complex No. 2 fortress anchors the base.
| Key location | Threat |
|---|---|
| Air Base Exterior | Critical |
| Air Base Bunker | Extreme |
| Admin Complex No. 2 (fortress) | — |
Access comes from the elevated woodland to the south.
Launch verification pending. Based on the official DMZ deep dive and the Hajin Tac Map (updated October 19, 2026). Bunker access routes, keys and loot will be verified in-game after launch and re-dated here.
