Where the Supreme Leader Access Card is
A fortified North Korean air base cut into a granite hillside, with a runway, helipad, hospital and barracks on the surface and an Extreme-threat bunker network underneath.
The report places the Supreme Leader Access Card door in Chang-san Air Base at grid B6: the Supreme Leader’s Bunker deep inside the Chang-san Air Base bunker. Our MW4 DMZ map marks Chang-san Air Base 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 Chang-san Air Base
- Chang-san Air Base is rated up to Extreme threat by Activision. Bring a full squad and plates, and plan the exfil before you open the door.
- Come in from the wooded high ground to the south, not the eastern cliffs.
- The bunker is Extreme threat: go in with a full squad and a plan to break contact.
