There are 37 different achievements you’re able to get inAtomfall, but many of them are hidden until you reach certain milestones. Since the game doesn’t tell you what these milestones are, it can be difficult for you to complete every major goal. Many hidden achievements are tied to the choices you make, so it’s best to know what decisions lead toward a 100% complete game.
You’ll start unlocking basic achievements early in the game for doing basic tasks. For example, the"Radiophonic"achievement is unlocked when you gather five different Audio Logs scattered throughout the alternate 1960s world of Northern England. In contrast, the rarehidden achievements are tied to much larger goals, which you can only pursue through specific decisions or the pursuit ofvarious Leads inAtomfall.

Every Secret Achievement In Atomfall
Meet Obscure Milestones From Your Choices
There are17 total hidden achievementsinAtomfall, with several being tied to the game’s multiple endings. Since the endings are tied to the choices you make throughout the story, you will likely need to complete multiple playthroughs to earn each secret milestone tied to the conclusion.
I’ve found that creating a save file right before an important decision makes it far easier to reach different endings for hidden achievements. Whenever you get one ending, you can load that save and make the opposite choice to make progress toward a different outcome.

The following tables show every hidden achievement you can unlock, as well as what you need to do to meet their requirements:
Do you require the Operator?

Combat
Completely destroy a robot.
Some hidden achievements are very straightforward, such as gaining access to the Oberon site or escaping the Quarantine Zone in under 5 hours. On the other hand,many of these milestones are deliberately vague, as they only allude to various goals. I’ve found that by dividing each hidden achievement into different types of objectives, they become far easier to complete.
How To Get Every Ending Hidden Achievement
The best way to get all the ending hidden achievements is toalways make choices that improve your relationship with a certain character. For example, if you need to reach the ending involving Mother Jago, ensure to help her during different Leads. The stronger your bonds are with certain characters, the closer you get to unlocking their unique endings.
