Atomfall has a few puzzles for you to solve, and one of the first that you will likely run into is at the entrance to Data Storeroom C, which is located in the Interchange’s Data Store Charlie. Here, there’s a locked door and a corpse with a key for it, but that’s not enough to make your way inside. Instead, you’ll need to also uncover a code to restore power to the door’s lock.
The game doesn’t hand you this code via a note or anything like that, however. You instead need to work it out for yourself using trial and error, and as a result, it’s rather easy to miss this Storeroom and the useful supplies that it has inside. To help you not do that, however, here’s how to solve the Data Storeroom C Code in Atomfall.
Atomfall Data Storeroom C Code
Data Storeroom C is found just below where you input the Atomic Battery for Data Store Charlie in Atomfall’s Interchange. This is likely one of, if not the first, Data Store that you restore power to.
If you head over to the Storeroom C door, you’ll see the corpse of a scientist just in front of it. First things first, loot his body for the Data Storeroom C Key. This won’t give you access to the Storeroom just yet, as the lock has no power, but once it does, you’ll need this Key to unlock the door.
With that out of the way, look at the tall server towers around the room and you should see that they all have numbered buttons on them. In our experience, there isn’t any note giving us a hint as to what the code is, and you have to figure it out using trial and error.
This isn’t as terrible as it might sound, because as you press each button, the tower will make a sound and light up if the button you pressed is deemed correct or not. For example, the first number of the code is 5. Listen to the noise that pressing that button makes, and then go about pressing the other buttons – after pressing 5 – until one makes that same noise and lights up.
Just remember that every time you press an incorrect button, you need to restart the code by pressing 5 – and whatever other numbers you have discovered – and then trying another button.
If you’d rather just know the code, rather than fiddling with the buttons, the correct code to power the Storeroom door is 5742 (click the spoiler tag to view).
Once you successfully input the code, power is restored to the Storeroom door, and you can then use the Key you looted earlier to unlock it.
Inside, you’ll find some ammunition, bandages, Training Stimulants, and a Poison Bomb Recipe.
