The Supreme Leader Bunker Key in Operation Iron Citadel unlocks a locked bunker with valuable loot. However, reaching the bunker can be tricky if you do not know where to look, especially with enemy soldiers guarding the military base. In this guide, we will show you where to find the bunker entrance, how to reach it safely, and where to use the Supreme Leader Bunker Key to unlock the loot room.
Where to Find the Supreme Leader Bunker
To use the Supreme Leader Bunker Key, start the Mission: Iron Citadel. The bunker is located inside the Chang-SAN Air Base, in the hilly area near the main compound.
Head toward the military base from the southern section of the map. As you approach the area, look for a large hole in the compound wall that leads down into the base. This is the route you need to follow to reach the bunker.
How to Reach the Bunker Entrance
Once inside the Air base, follow the path downhill toward the buildings below. You will eventually reach the military base’s main structures, where several enemies may be waiting. You can try to use stealth to avoid unnecessary fights, but be prepared for combat if the enemies spot you.
Continue down the hill until you reach the buildings near the main compound. Refer to the location on the map. Drop down to the lower area and look for the entrance to the bunker section.
Where to Use the Supreme Leader Bunker Key
After reaching the lower area, head into the bunker. Clear any enemies around the entrance before moving inside. Look for the large doorway marked with 01. Go through this door and continue along the corridor.
Keep moving until you see red lettering above a door. From there, head down the stairs toward the large bunker doors. This is where you can use the Supreme Leader Bunker Key to access the locked room.
