In February 2026, Atomic Heart turns three years old. Mundfish presented festive promotional art and also addressed the players:
Atomic Heart has its 3rd birthday! From the first steps at Enterprise 3826 to a universe that continues to expand and go beyond its origins — thank you for entering our world of crazy robots, bold ideas and unforgettable moments. We are glad that you are with us — the most interesting is yet to come.
Currently, the Atomic Heart developers are preparing the fourth story DLC "Trouble" for the game.
