Atomic Heart is a first person action game set in an alternate Soviet future where advanced robotics have gone catastrophically wrong, turning helpful machines into hostile threats across a stylized, retro futuristic world.

Players fight through both open areas and enclosed facilities using a mix of firearms, melee weapons, and special glove based abilities that can be combined for varied combat approaches. Crafting and upgrading gear supports survival against increasingly dangerous robotic enemies, while the distinct art direction and story ground the action in its unusual setting.
