In a dystopian future where city skyscrapers have become autonomous fortresses, players assume the role of a renegade engineer who hacks these living structures to extract their hidden treasures. Each fortress presents a unique set of challenges—riddles, monster minions, and moral dilemmas that influence the outcome of the story. Players make choices to navigate the ever-changing environment while forming alliances (or betrayals) with other rogue engineers. The game emphasizes storytelling, resource management, and character development, leading to multiple endings based on the player's decisions.
