Atomic Heart Length: How Long To Beat?

Atomic Heart's length to complete can change by over a dozen hours depending on how much you want to complete, and what type of playstyle you prefer.
For those looking to just mainline the story, ignoring side areas, the open world, and any collectables, it will take you roughly 10-15 hours. The start of the game will likely be the longest part of this, as it takes several hours before you arrive in the open world area, but after this, each story area takes much less time to complete.
For those looking to mostly focus on the story while also exploring and collecting some things like weapon upgrades, your playtime will likely come in around 20-25 hours.
Finally, for players looking to take the completionist route by securing every collectable and exploring everything the game has to offer, you'll likely be playing the game for around 40 hours in total.

It's worth noting that the difficulty you play on will factor in to how long the game takes, with higher difficulties requiring you to put more thought into how you approach encounters and spend more time gathering resources for upgrades and crafting.
