Mundfish Games has officially announced the sequel to its acclaimed action-adventure FPS, Atomic Heart, which originally sold over 10 million copies. The new installment, Atomic Heart II, is set to launch on PC, PlayStation 5, and Xbox Series X/S, promising to elevate the franchise with a broader scope and deeper gameplay.

Atomic Heart II is an action-adventure role-playing game set in a richly detailed retrofuturistic alternate-history universe. It expands the narrative from the original, unfolding a gripping global story filled with mysteries and high stakes. Players will experience a living world teeming with activities, minigames, and side quests that enhance immersion and player freedom.

Built using Unreal Engine, the game boasts realistic graphics that vividly depict a dystopian yet utopian world where humans once lived in harmony with robots. However, this peace has collapsed into chaos, setting the stage for players to uncover deeper truths and prevent global catastrophe.

Key gameplay innovations include an enhanced combat system that allows players to wield weapons and glove abilities simultaneously with both hands, creating dynamic and explosive combat scenarios. The expanded RPG mechanics offer a variety of ways to engage with the world, making player choice and freedom central to the experience.

The inspiration behind Atomic Heart II draws from iconic titles such as BioShock, Cyberpunk 2077, and Metro Exodus, blending narrative depth with open-world exploration and RPG elements. This positions the sequel as a strong contender in the genre, aiming to match or exceed the success of its predecessor.

Robert Bagratuni, CEO and founder of Mundfish, expressed pride in the franchise’s success, highlighting the achievement of creating a new IP that stands alongside renowned franchises like BioShock and Fallout. With over 10 million players and multiple DLC packs released since 2023, Atomic Heart has established a strong foundation for its sequel.
