Discovering All Secret Achievements in Atomfall

Atomfall offers a total of 37 distinct achievements, many of which remain hidden until you hit specific milestones in the game. Since the game does not explicitly outline these milestones, players may find it challenging to accomplish every primary objective. A number of hidden achievements relate to the choices you make throughout the game, so understanding which decisions contribute to full completion is beneficial.

As you start your journey in Atomfall, you’ll unlock basic achievements for completing simple tasks early on. For instance, the achievement titled “Radiophonic” becomes available when you collect five different Audio Logs scattered across the alternate 1960s landscape of Northern England. In contrast, rare hidden achievements are linked to larger goals that can only be achieved through certain choices or by pursuing various Leads within the game.

All Secret Achievements in Atomfall

Discover Hidden Milestones Through Your Choices

In total, there are 17 hidden achievements in Atomfall, many of which are associated with the different endings of the game. Since these endings depend on your choices throughout the narrative, you’ll likely need to replay sections of the game to achieve every secret milestone linked to the conclusions.

The tables below detail each hidden achievement you can unlock, alongside the steps needed to fulfill their requirements:

Some hidden achievements are quite clear, such as gaining entry to the Oberon site or escaping the Quarantine Zone in under five hours. However, many of these milestones are purposefully ambiguous, referring only to various objectives. Organizing these hidden achievements into distinct types of tasks can make them easier to accomplish.

How to Unlock Every Ending Hidden Achievement

To unlock all the ending hidden achievements, focus on making choices that enhance your relationships with specific characters. For example, if your goal is to reach the conclusion involving Mother Jago, ensure you assist her with different Leads. The stronger your connections with particular characters, the closer you’ll get to unlocking their unique endings.

Some characters can be more difficult to build relationships with than others, especially if you’re not sure where to locate them initially. Here are quick hints to help you find characters linked to endings, so you can build connections quickly before you depart from the Quarantine Zone:

• Dr. Garrow – located in Skethermoor (a heavily fortified Protocol area)
• Joyce Tanner – found in a secluded bunker in Casterfell Woods
• Mother Jago – located in The Old Mines in Casterfell Woods
• Captain Sims – found 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

How to Unlock Every Data Store, Collectible, and Area Unlock Hidden Achievement

Data Stores are special spots you can locate within the world, which initially have no power. You need to gather Atomic Batteries in Atomfall to get these Data Stores functioning again. Collecting multiple Atomic Batteries is required for unlocking each associated achievement. When you use an Atomic Battery to access a Data Store, you’ll reveal a vault filled with treasures and collectibles.

Once you’ve activated all four Data Stores, you can collect the Signal Redirector to access the Oberon site. Achieving this grants you two additional hidden achievements, but you must follow these steps:

1. Acquire 4 Atomic Batteries.
2. Use the Atomic Batteries to power each Data Store.
3. Retrieve the Signal Redirector from the Storage Room in Skethermoor Prison (where Dr. Garrow is stationed).
4. Activate The Interchange Central Processor.
5. Unlock access to the Oberon Site.

How to Unlock Every Combat Hidden Achievement

The final hidden achievements are connected to combat with the various robotic opponents you will encounter in the Quarantine Zone. Although they may seem intimidating, you can target the weak points on these robots to make progress toward the related achievement. When a robot is staggered or weakened, you have the option to either destroy it or remove its battery, both of which contribute to unlocking hidden achievements.

Unlocking any secret milestone will help you get closer to claiming the ultimate achievement of the game, “Pride of Britain,” which you earn after gathering all other trophies. Collecting all hidden achievements is essential if you aim for a complete 100% experience in Atomfall, an immersive game driven by player choices.
