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]

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]
