Atomic Heart 2 is an upcoming action-adventure role-playing video game developed and published by Mundfish. It is the sequel to Atomic Heart and was announced during the Summer Game Fest in June 2025.¹

Atomic Heart 2 continues the alternate-history setting of its predecessor, where a retrofuturistic Soviet-era aesthetic blends with dystopian sci-fi themes. The sequel expands the scope of the game's world, featuring events on a global scale, compared to the more isolated environments of Atomic Heart.²

Atomic Heart 2 is a first-person shooter with role-playing mechanics. It will include deeper role-playing systems, such as skill upgrades and special abilities, alongside a wider variety of weapon customizations and combat strategies. The combat includes both ranged firearms and melee elements, with new robotic enemies and environmental hazards.³

The sequel picks up after the events of the first game, with the player navigating a world on the brink of societal collapse. Players are tasked with confronting new threats across various locations and dealing with the consequences of earlier developments in the game's universe.⁴

According to Mundfish, the narrative will explore more diverse geopolitical regions and involve more morally complex themes, including the ethics of artificial intelligence and control.⁵

Plans for a sequel to Atomic Heart were in place as early as 2021, two years before its release.⁶ At that time, developers at Mundfish had indicated their interest in expanding the franchise. In June 2023, the studio head confirmed that development on a sequel had begun.⁷⁸

Atomic Heart 2 was formally announced on June 8, 2025, during the Summer Game Fest. Along with the sequel, Mundfish also revealed The Cube, a standalone multiplayer role-playing shooter set in the same universe.⁹

The game is expected to launch on Microsoft Windows, PlayStation 5, and Xbox Series X/S.¹

Initial coverage from media outlets such as IGN, PC Gamer, and GameSpot highlighted the game's ambitious scale and visual style. While some previews compared it to a blend of genres ranging from BioShock to open world role-playing games, others noted its blend of Soviet aesthetics and speculative fiction themes.³
