In a near-future world where organ transplants are common, players assume the role of Sam, a quirky forensic linguist tasked with solving the mystery of a missing organ donor. As you investigate, you quickly discover that the heart you’re dealing with isn’t just any heart; it has unique properties that link it to unsolved crimes, a covert underground organ trade, and a shadowy government conspiracy. Players must navigate volatile relationships, extract confessions from suspects through dialogue puzzles, and piece together a chilling narrative as they uncover the heart's true origin. Each choice you make affects the outcome, leading to multiple endings that explore themes of identity, morality, and the lengths to which people will go for love and life.
