In the immersive world of Atomfall, players encounter a key character – a mysterious voice that guides through a vital task: locating four elusive Interchange doors. These doors are critical for advancing the narrative and unveiling the mysteries of the game.
However, discovering the locations of these doors can be quite a challenge, as the game offers minimal guidance. Players are encouraged to look for paper clues or other hints scattered throughout the environment.
Each of the four distinct regions in Atomfall conceals one of these hidden Interchange doors, and finding them not only enhances gameplay but also simplifies the exploration process.
Strategies for Locating All Interchange Doors in Atomfall

Successfully locating all four Interchange doors allows players to access different sections within the game and various Data Stores (labeled A, B, C, and D) of the Interchange. Each door requires an Atomic Battery to activate its corresponding power, and powering up these Data Stores is essential for escaping quarantine and completing the game.
Exploring Wyndham Village
The first Interchange door players are likely to discover is situated in Wyndham Village, specifically located at 33.8E, 78.3N, near the notable St. Katherine’s Church.
This entrance leads directly to Data Store A, but be cautious! It is enveloped in a mysterious substance that progressively drains your health. For a safer exploration, it’s advisable to first locate Mother Jago and acquire the Strange Tonic recipe, which mitigates the harmful effects of the substance.
Navigating Slatten Dale
The Interchange door in this area provides access to both Data Store C and Data Store D, as well as a route leading back to the Central Processing section.
Players will also discover the entrance to the Medical Wing here, encountering a new enemy type known as “Thralls, ”which adds an interesting layer to combat dynamics.
Finding the Door in Castlerfell Woods
In Castlerfell Woods, the Interchange Door can be found at 27.6E, 83.6N, positioned in the southeastern area of the map, conveniently close to the Wyndham Village entrance.
This door is crucial for progressing the main storyline, though the area itself reveals little in the way of resources. It primarily serves to create easier navigation between the Wyndham Village Interchange section and the Central Processing area.
Unveiling Skethermoor
The Interchange door in Skethermoor is located at 39.6E, 73.1N, just north of Skethermoor Prison. Be prepared to encounter a robot turret guarding the entrance.
Players can choose to either stealthily bypass the turret or deactivate it using the Signal Redirector if they possess one. This door leads to Data Store B, where players can revive power via an Atomic Battery, alongside facing hostile Protocol Soldiers.
Additionally, accessing the Robotics section from this door provides opportunities to gather valuable Training Stimulants, essential for enhancing your capabilities.
