In a dark, twisted world where hearts can be exchanged for memories and emotions, players take on the role of a heart merchant who discovers a black market for hearts stolen from unwilling victims. As they navigate a dense urban landscape rife with corruption, unstable alliances, and terrifying secrets, players must choose which hearts to trade, confront hauntingly vague memories that start to merge with their reality, and ultimately decide what it means to have a heart in a world stripped of humanity. Each decision echoes through the environment, affecting both relationships and the city itself.
