  • Find and extract the Al Mazrah Shipping Intel found in Room 403 of the Ashika Island Hotel.
  • Take the Building 21 USB stick from the Dead Drop in the Waterways.
  • Place the Building 21 USB stick in the hotel room.

Before attempting this mission, we recommend that you complete the second task of retrieving the Building 21 USB stick first. This way, you will not have to go back and forth to the hotel room. Furthermore, you will need a Lost Room 403 Key for this mission as the hotel room is a locked space. This key can be acquired by killing HVTs on the map and also as a random loot item.

Where to find the Building 21 USB stick in DMZ

At the southern corner of the Tsuki Castle Hideout (green marker on the map above), you'll find a cave entrance. Enter this cave and keep to your left until you find a rope that leads underground. Descend down the rope and you'll reach the Waterways submarine dock right underneath Ashika Island. Head right from the docking platform and you'll be easily able to spot the Waterways Dead Drop. Interact with the dumpster and pick up the Building 21 USB placed inside it. The Waterways and Tsuki Castle areas are heavily guarded, so tread carefully and try to stay undetected as you wouldn't want to lose the Lost Room 403 key.

Now, head back up either the same way you came from or swim to the water channel exit near Town Center and Beach Club, which will lead you directly to your destination. Room 403 is a locked space on the top floor of the Ashika Island Hotel, which is located next to the City Hall building. To reach the locked hotel room, you can either take the zipline inside the building or the staircase on the outside. Unlock the steel door using the Lost Room 403 Key you brought into the match. In the corner of the room, you'll find a table with a metal briefcase and other loot items. Place the Building 21 USB stick on the table and grab the Al Mazrah Shipping Intel. Finally, extract the document to complete the Intel Exchange DMZ mission.
