The Buried City Hospital Key opens a high‑tier loot room inside the hospital on the Buried City map. Keys are rare and spawn inconsistently, but there are reliable places to check and a consistent route to the door once you have one.

Find the Buried City Hospital Key (best spots)

Key drops are random and can come from many containers, but residential and office interiors tend to produce them more often. Two locations on Dam Battlegrounds are especially worth your time:

Location Map area What to look for
Ruby Residence apartments Western/northwest Dam Battlegrounds A cluster of three ruby‑red apartment buildings. Sweep every floor and room.
Research & Administration Eastern Dam Battlegrounds Second‑floor loot area that frequently rolls random keys.

Keys can still drop from other containers on any map, so expect some runs without results. When you do find one, remember that dying before extraction will cost you the key.

Tip: stash keys in Safe Pockets to keep them through an extract even if things go sideways mid‑raid.

Use the Buried City Hospital Key (third‑floor route)

The hospital sits on the north side of Buried City (roughly the northwest quadrant on the map) and is marked as a red‑outlined rectangular complex. The key opens a locked room on the third floor.

  • Enter on the ground floor near the Northern Metro Station entrance.
  • Go through the doorway marked “OSPEDALE.” Stairs are immediately on your left.
  • Take the stairs to the third floor.
  • On the third floor, turn left into the long corridor. Move past the first door.
  • At the corridor’s end, turn left into a locker room (red lockers, hanging clothes).
  • Cross the locker room and exit through the far door.
  • Take an immediate right. The locked door that uses the Buried City Hospital Key is here.

Interact to unlock. Inside, you’ll find multiple searchable points—roughly ten—which can include weapons, blueprints, consumables, valuables, and occasionally other keys.

Note: the hospital qualifies as a high‑tier loot area. Expect roaming ARC patrols in the hallways and stairwells. Clearing nearby enemies before you start looting reduces the risk of getting pinned in tight interiors.

Loot the room and extract safely

Loot contents are randomized. The room often yields several items valuable enough to justify the risk and the key spent. When you’re done, backtrack to the ground floor: the Northern Metro Station entrance you passed on the way in is a reliable extraction option with minimal exposure.

If you’re working through the Medical Merchandise objective, visiting this location helps move that track forward, so consider bringing the key when you plan to focus on that task.

Quick checklist

  • Farm the key on Dam Battlegrounds: prioritize Ruby Residence and Research & Administration.
  • Store the key in Safe Pockets before pushing objectives.
  • Reach the Buried City hospital, enter via the ground floor near Northern Metro Station.
  • Go “OSPEDALE” door → left stairs → third floor → left corridor → locker room → exit → immediate right to the locked door.
  • Clear hostiles, loot the room’s search points, and extract via Northern Metro Station.

Treat the hospital as an in‑and‑out run: bring the key, sweep the third‑floor room, and leave through the nearby metro while the odds still favor you.
