The report places the Mirae Electrical Room door in Mirae General Hospital at grid F5: the electrical room in the northwestern basement parking garage of the hospital. Our MW4 DMZ map marks Mirae General Hospital 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 Mirae General Hospital
- Mirae General Hospital is rated up to Low threat by Activision. A duo or a careful solo run is realistic, but expect other squads drawn to the same loot.
- Low threat overall, but watch the wooded ridge to the south for snipers.
- Use the colour-coded floor signs to call out positions.
