Discover the location of the Church Cellar Key in Atomfall's The Interchange Medical section and learn how to use it in Wyndham to find Dr. Holder and gain Infection resistance.

Walkthrough
  1. 1
    To find the Church Cellar Key, you first need to head to The Interchange. Ensure you have at least one Atomic Battery. You can purchase one from Trader Molly in Slatten Dale (Map Marker) at 26.3 E, 79.0 N.
  2. 2
    Enter The Interchange from the Slatten Dale entrance (Map Marker). Use an Atomic Battery to power the Central Processing Unit.
  3. 3
    Open Data Store Charlie (southwest section). Go downstairs and use another Atomic Battery to power up the Medical section.
  4. 4
    Exit the door where you used the Atomic Battery, cross the central part of the facility, and enter the door directly ahead. Go up the stairs to the top, then turn left through the door to find the entrance to Medical.
  5. 5
    Once inside Medical, head west from the main control room and follow the corridor. Deal with the Thralls found there.
  6. 6
    Continue following the corridor until you reach a dead end down some stairs. Crawl through a small gap to the left to enter the Ward Corridor.
  7. 7
    Walk forward to an intersection, then head east down the main corridor to the end. Explore and loot resources.
  8. 8
    Turn south at the back wall and look left to find a dead end containing the Church Cellar Key and the Log: Holder is up to something, which starts the Holder Lead.
  9. 9
    To use the key, travel to Wyndham village. Head down the main street and enter the large church on your right (Map Marker).
  10. 10
    On the ground floor, find the stairs leading down to a locked door. Use the Church Cellar Key to open it.
  11. 11
    Inside, you will meet Dr. Holder, find Training Stimulants, and acquire the Experimental Inoculation, which grants Infection resistance and unlocks new Conditioning Skills.
Tips
  • Before entering Medical, ensure you have ample healing items and ammunition, as it is populated by dangerous Thralls.
  • Be cautious when exiting The Interchange, as Outlaws may appear.
  • In Wyndham, you can bargain with Vicar McHenry using information from Trader Molly about his Atomic Battery to potentially obtain the key for the chest upstairs, though this is separate from the Church Cellar Key.
