Lab entry and separate lockers

  • Go to the basement morgue at Mirae General Hospital and match the Chemical Lab lock. F5 identifies the hospital area, not a measured doorway.
  • The Hospital Chemical Lab Key provides lab entry. It does not establish access to every chemical locker inside; compare the separate Hospital Chemical Lockers listing.
  • The Doctor's Command Office and Mirae Electrical Room use different keys. Their routes and loot do not establish the lab's contents.

Finding the key

  • An original creator guide covers the lab-key route at Mirae General Hospital. No repeatable key drop or fixed pickup is established here; confirm the named card before planning entry.
