Mundfish

Developer Mundfish has stated in the past that Atomic Heart should take at least 20 hours to complete. While they didn’t go into specifics, we’d expect that this is when playing through the story at a steady pace while wandering off the beaten path from time to time.

A full completionist run will likely take closer to 30 or 40 hours if you’re planning on unlocking every achievement along the way. The world is dense and full of secrets to discover, so it will take a serious time commitment to see everything the game has to offer.

Of course, these numbers will also vary depending on which difficulty players select at the beginning. Those on the lowest setting will be able to breeze through each combat encounter and power through the story, while those looking for a challenge might get hung up on one of the savage boss fights.

Ultimately, it all depends on how you want to play. But fans who purchase Atomic Heart, or pick it up on Game Pass, can rest assured that they’ll get at least 20 hours of gameplay before hitting the credits.
