Blue Book is a visual novel in the detective and science fiction genres. Become an FBI agent and investigate the disappearance of people in a small town. Play out different behavior patterns to interrogate locals and notice inconsistencies in their testimonies. Discover the truth: are UFOs behind these kidnappings?

Open World. Immerse yourself in the atmosphere of Rosland — a small provincial town in Kansas in the mid-1980s. Freely move around the police station, hospital, library, and a variety of other locations. Explore every corner to uncover the full truth about what’s happening in the town.

Action Cards. Pressure witnesses, take on the role of the “good” and the “bad” cop, show friendliness, slam your fist on the table, joke, or be serious — the visual novel gives you the opportunity to choose action cards depending on the situation.

Evidence System. Collect important evidence for your investigation. Carefully examine the clues you find. Don’t miss a single detail that can help identify those behind the kidnappings in Rosland.

Hypotheses and Conclusions. Build hypotheses based on conversations with witnesses and victims. Reach logical conclusions from the evidence gathered. But be cautious — every decision will have its consequences.

Unique Dialogues and Unforgettable Characters. You will encounter locals with unique personality traits and behavioral patterns. Use your observation skills and pay close attention to each of them. Maybe the residents of Rosland are not as simple as they seem at the first glance… The unique dialogue system will help you find out for sure.

“Blink” System. Sometimes you will face situations that require immediate and precise reactions. Be attentive and decisive, because hesitation could cost someone’s life.

Puzzles. During your investigation, you will find yourself in places where you’ll need to think carefully about your actions. Only by doing so can you progress further.

Collectible Items. While investigating, you may come across unique items. From them, you’ll learn about the most famous UFO sightings and other mysterious phenomena people have encountered. Keep your eyes open to collect all the collectibles.

Multiple Endings. Complete your investigation with one of three unique endings, each determined by your actions. Don’t be discouraged if the ending disappoints you — you can always start the investigation anew.

In the demo version, you will be able to complete the first two chapters of the story.

開発者はコンテンツを次のように説明しています：

The developers describe the content like this:

The game contains mature content, including stylized scenes of violence (murders without naturalism, there is no realism of blood and dismemberment), moderate use of obscene language (veiled swearing).
There are no scenes of a sexual nature — all relationships are described within the framework of the general plot, without frankness.
The material is intended for adults: an age limit (18+) is recommended.
The game is a visual novel with detective and psychological elements, so the content may seem heavy, but everything is presented in an artistically restrained form.
