Story intro

AI: The Somnium Files is a mystery adventure game that is split into two types of sections: investigation and somnium parts. The story progresses through branching paths leading to multiple different endings, based on choices the player makes; the player only gets a full view of the story by playing through each route. Rather than starting over from the beginning several times to see different paths, the player can skip directly to the branching points using an in-game flow chart. During the investigation parts, the player character, as detective Kaname Date, uses his artificial intelligence unit Aiba's functions, such as X-ray vision and zooming, to further the investigation in the real world. During the somnium parts, Date uses a machine called the Psync Machine to enter the memories of suspects or key witnesses who do not want to share information with him, in the form of dreamscapes called "somnium", to find clues and extract the information by solving puzzles. The puzzles involve examining objects and choosing an action to perform with it, and solving mental locks - obstacles standing in the way of clues - allowing the player to sink deeper into the character's subconscious. There is a six-minute time limit before the dreamscape collapses, and as actions take time to perform, the player must be careful in deciding what to do. Within the somnium parts, Aiba takes on the form of a humanoid and acts as the player avatar. AI: The Somnium Files takes place in a technologically advanced Tokyo in the near future, and follows Kaname Date and his top-secret team within the Tokyo Metropolitan Police Department, known as the Advanced Brain Investigation Squad (ABIS). ABIS is responsible for investigating crimes through the process of Psyncing, exploring the subconscious dreams of persons of interest via a machine connecting the two together in a dream state known as Somnium. ABIS agents doing such are known as Psyncers, and act as observers in subjects' dreams who are able to retrieve secrets and clues the subject may be hiding or may not be aware of. To ensure psyncers are not subject to adverse effects, their time in a subject's somnium is limited to a maximum of six minutes. Also featured in the universe is the topic of advanced Artificial Intelligence, based around a global cloud-based system known as the Wadjet System that acts as the core of AI. Kaname Date is called to a murder scene at Bloom Park in the quarantined Kabasaki district, where Shoko Nadami's corpse is found tied to a carousel horse with her left eye removed. Searching the area, Date finds Shoko's daughter Mizuki in the carousel's central column, clutching the murder weapon and suffering from aphonia. Date investigates the phone call made to the police about the scene, leading to his friend Renju's company Lemniscate as well as Ota and Iris. At the end of the day, it's decided for Date to psync with Mizuki to learn more about what happened and hopefully cure her aphonia.
