As if awakening from a deep sleep, you find yourself in a strange, contradictory world of ancient ruins and advanced technology. Tasked by your creator with solving a series of increasingly complex puzzles, you must decide whether to have faith or to ask the difficult questions: Who are you? What is your purpose? And what are you going to do about it?Features: Overcome more than 120 immersive puzzles in a stunning world. Divert drones, manipulate laser beams and even replicate time to prove your worth - or to find a way out. Explore a story about humanity, technology and civilization. Uncover clues, devise theories, and make up your own mind. Choose your own path through the game's non-linear world, solving puzzles your way. But remember: choices have consequences and somebody's always watching you.
