Dive into Blue Book — a detective game with elements of science fiction, where you are to independently investigate a series of mysterious disappearances in a provincial town in the USA of the 1980s.

Gather clues, interrogate residents, and build your own hypotheses. Some leads will turn out to be false, and wrong conclusions can change the course of the investigation. The game does not give ready answers — only facts, contradictions, and your own decisions.

You are an FBI agent sent to Roseland, Kansas, where residents begin to disappear without a trace under strange circumstances. While the local police prefer to turn a blind eye to what is happening, you are to figure out: is a person behind the events... or something beyond ordinary reality.

ACTION CARDS: TACTICAL DIALOGUES

Every conversation is a duel. Use the unique "action cards" system: become the "good cop" by showing empathy, or the "bad cop" by pressuring the witness with authority. Your choice instantly changes the atmosphere and reveals hidden sides of the characters.

CLUE SYSTEM: ASSEMBLE THE PUZZLE

Every photograph or note is a key to the mystery. Study clues, combine them, and build logical chains. Your conclusions will determine the fates of Roseland's residents and your career. Remember: the consequences are irreversible.

"BLINK" SYSTEM: THINK FAST

Investigation is risk. In critical moments, the "BLINK" system activates: you will have split seconds to get a suspect talking, dodge a bullet, or prevent a tragedy. Delay can cost a life.

YOUR DECISIONS DICTATE THE OUTCOME

Non-linear dialogues allow you to carve your own path to the truth. Your tone of communication, the questions asked, and even your silence forever change the course of the story.

YOUR DECISIONS DETERMINE THE ENDING

The ending of your investigation is a direct consequence of every choice: who you suspected, which testimony you believed, and what methods you used. The game offers several unique endings — will you manage to triumphantly solve the case, or come face to face with the unthinkable? An unsatisfying ending is not the end, but a reason to start over and find another truth.
