In a not-so-distant future, players assume the role of Fiona, a rogue bioengineer in an underground society where heart transplants are a black market commodity. After a heist gone wrong, Fiona steals a genetically-modified heart that has been infused with AI capabilities. As she navigates the treacherous underbelly of the city, Fiona forms an unusual bond with the heart's consciousness, which has its own motives and dark secrets to unveil. Players must make choices that determine not just their survival, but also the fate of the heart’s previous owner—before time runs out and the AI heart’s power fully awakens. Will you choose loyalty, self-preservation, or unravel deeper mysteries? Each decision branches into tense scenarios where trust is fragile and betrayal lurks around every corner.
