Where to Find the Church Cellar Key¶

You don’t need to necessarily need to chance upon the locked door in Wyndham before you go searching for this key, you can find it first and then make your way to Wyndham. Regardless of the order of events, all roads lead to The Interchange, where you’ll need to make sure you have at least one additional Atomic Battery on you if you’re heading there for the first time. There are six of these in total (including the initial one you can’t miss in The Interchange itself), but the easiest one to get is by purchasing it from Trader Molly in Slatten Dale (Map Marker), over to the north (at 26.3 E, 79.0 N).

Once you have the necessary items on you, head for The Interchange, preferably from the Slatten Dale entrance (Map Marker), and after using an Atomic Battery to power up the Central Processing Unit, go and open Data Store Charlie (the southwest section of the facility). Once inside, head down the stairs and use another Atomic Battery to bring power to this section, this is what will allow you to get into Medical.

To reach Medical, you’ll need to head out of the door where you placed the Atomic Battery, go across the central part of the facility and into the door directly ahead of you, then go up the stairs to the top and then left once through the door to find the entrance to Medical.

Searching Medical¶

You’ll want to make sure you have ample supplies of healing items and ammo before you continue, Medical is littered with Thralls, deadly Ferals that move slowly, but have a lot of health. Begin by heading west once you reach the main control room and follow the corridor around, at the bottom you’ll find some Thralls that you should deal with so you don’t have to worry about them later.

Continue follow the corridor around until you reach a dead end down some stairs, just to the left of those is a small gap you can crawl through to reach the Ward Corridor. Walk forward to reach an intersection and then head east down the main corridor to the end (feel free to explore and loot the resources here), you’ll eventually reach the wall at the back, turn south to continue and then look immediately to your left to find a dead end with the Church Cellar Key and the Log: Holder is up to something, which will start the Holder Lead and give you an idea on where to use this key.

Using the Church Cellar Key¶

If you’ve yet to even go to Wyndham yet, you may be wondering what this key you’ve just picked up is for. As the note mentions, there appears to be an underground lab in the village, so with that knowledge, make your way out of The Interchange (Outlaws will show up now, so be careful on the way out) and over to Wyndham. If you’re exiting into Slatten Dale, you can make a quick dash over to the west to find the entrance to the village.

Once there, head down the main street and near the bottom of it, you should spy a large church on your right (Map Marker). Head on over and enter it and you’ll run into Vicar McHenry who asks you to keep quiet about a murder, if you got the rumor from Trader Molly in Slatten Dale about his Atomic Battery, this is the perfect time to bargain with him and get the key for the chest upstairs.

Regardless, look around on the ground floor and you’ll find some stairs leading down, follow them and you’ll eventually reach a locked door that requires the Church Cellar Key. Inside, you’ll finally meet Dr. Holder, find a number of Training Stimulants, and get your hands on the Experimental Inoculation that will grant you resistance to Infection along with unlocking some other new Conditioning Skills.
