In the captivating world of Atomfall, players have the opportunity to unlock a total of 37 achievements. However, many of these remain obscured until you hit specific milestones throughout your gameplay. The challenge lies in the fact that the game doesn’t provide clear indicators of these milestones, making it a challenge for players aiming for 100% completion. Many of the hidden achievements are intricately linked to player choices, emphasizing the importance of strategically navigating decisions to meet every goal.
As you embark on your journey, basic achievements can be unlocked fairly early by accomplishing straightforward tasks. For instance, the “Radiophonic”achievement activates after gathering five unique Audio Logs, cleverly placed around the alternate 1960s landscape of Northern England. Conversely, the elusive hidden achievements are often associated with grand objectives, which can only be achieved by making particular choices or engaging with various Leads within Atomfall.

Uncovering Obscure Milestones Through Choices

There exist a total of 17 hidden achievements in Atomfall, several of which correlate directly to the different endings available in the game. Given that these endings hinge on your in-game decisions, you may need to undertake multiple playthroughs to unlock all the hidden milestones associated with each conclusion.
To streamline your efforts in achieving distinct endings for hidden achievements, it’s advisable to create separate save files just before pivotal decisions. After concluding one pathway, loading the save file allows you to explore opposing choices, thereby facilitating progress toward another ending.
The tables below outline each hidden achievement and the specific requirements needed to unlock them:
Hidden Achievement | Achievement Type | How To Unlock |
---|---|---|
Back Door | Ending | Escape the Quarantine Zone with Dr. Garrow. |
Emergency Extraction | Ending | Escape the Quarantine Zone with Joyce Tanner. |

By categorizing each hidden achievement into distinct types of goals, players can simplify the process of completing each one.
Strategies for Unlocking All Ending Hidden Achievements



To successfully acquire all ending hidden achievements, it’s crucial to focus on decisions that strengthen your connections with specific characters. For instance, if your goal is to achieve an ending featuring Mother Jago, be sure to assist her during vital Leads. The more robust your relationships with these characters become, the closer you’ll be to unlocking their unique narrative conclusions.
Character interactions can be tricky to navigate, especially if you’re unsure where to find them. Here are some quick tips to help you locate each character and establish relationships expediently before departing the Quarantine Zone:
- Dr. Garrow: Located in Skethermoor (a heavily guarded area).
- Joyce Tanner: Found in a secluded bunker within Casterfell Woods.
- Mother Jago: Encounter her in The Old Mines of Casterfell Woods.
- Captain Sims: Situated in the Village Hall of Wyndham Village.
- Voice on the Telephone: Accessible via any call from a red phone booth.
- Dr. Holder: Encountered naturally through the main storyline.
Acquiring Data Store, Collectible, & Area Unlock Hidden Achievements

Data Stores are unique locations scattered throughout the game, each initially powered down upon discovery. To restore power, you must collect Atomic Batteries; accumulating several of these rare items is essential for unlocking relevant achievements. Employing an Atomic Battery to access a Data Store door rewards you with a cache of resources and collectibles.
After successfully unlocking all four Data Stores, players can collect the Signal Redirector, which grants access to the Oberon site and unlocks two additional hidden achievements. To achieve this, follow these steps:
- Collect 4 Atomic Batteries
- Use Atomic Batteries to activate all Data Stores
- Retrieve the Signal Redirector from the Storage Room in Skethermoor Prison (where Dr. Garrow is located)
- Activate The Interchange Central Processor
- Gain Access to the Oberon Site
Unlocking Every Combat Hidden Achievement

The final category of hidden achievements relates to combat against the diverse robotic adversaries found in the Quarantine Zone. Although these foes can be quite challenging, players can target the weak points of the robots to advance towards both combat-related hidden achievements. Successfully staggering a robot by dismantling its weak points allows you to either destroy it entirely or extract its battery, achieving progress with these milestones.
Accomplishing any secret milestone gets you closer to unlocking the ultimate achievement in the game, known as “Pride of Britain,”which is awarded when all other trophies are acquired. Collecting every hidden achievement is essential for players wanting to achieve 100% completion in Atomfall, an immersive experience rich with decision-driven gameplay elements.
