X01 Black Site is the underground Exclusion Zone added to Call of Duty: Modern Warfare 4 DMZ in Season 1. It has two floors, its own exfils and bosses, and a 3D Printer that makes items the FOB printer cannot.

How to get in

The entrance is a freight elevator in the northwest corner of Hajin. In the app the X01 marker on the Hajin map opens the X01 floor plans. The exact door and elevator are not verified in game yet.
