關於此遊戲

Dive into Blue Book, a narrative quest at the mix of sci-fi and detective stories. Keep an eye on every clue — even the smallest detail could lead you to the people right behind the disappearances in Roseland.

You are the last hope for a case that everyone else has turned their back on. Journey to Kansas, where a series of mysterious disappearances is tormenting the citizens of a province town. Investigate the strange events that the police have decided to hide in their archives. Analyze the evidence, uncover contradictions in the testimonies of the witnesses, and decide: are you dealing with a genius criminal or a phenomenon that challenges reality itself? Your intuition is your last guide when logic fails.

ACTION CARDS

Every dialogue is a tactical duel. Blue Book provides a unique tool: at key moments, you choose an “action card” that determines your approach. Decide whether to be the “good cop,” showing empathy and kindness, or the “bad cop,” pressuring the witness or smashing your fist on the table. Your choice instantly changes the atmosphere of the conversation and reveals different sides of the characters.

EVIDENCE SYSTEM

Every piece of evidence you find — from photos to personal notes — is part of the puzzle. Examine the evidence, piece it together, and build logical chains. Use witness statements and collected evidence to form working hypotheses. Your final conclusion will determine the direction of the investigation, but remember: every decision has irreversible consequences for the residents of Roseland and your career.

«BLINK» SYSTEM

Investigation is not just about methodically gathering evidence. At critical moments, you need to react instantly. When the «BLINK» system is activated, you have a few seconds to make a decision: to get information from the person you are talking to, to avoid danger, or to prevent a tragedy. Hesitation or a mistake can cost a life — yours or someone else's.

COMPLEX DIALOGUE SYSTEM

Every word you say matters. Dialogues are non-linear: your tone, the questions you ask, and even your silence can open or permanently close narrative threads. Some characters will only reveal secrets if they trust you completely, while others can be broken by tough confrontation. You create your own path to the truth through thousands of lines of text.

VARIETY OF ENDINGS

The finale of your investigation is a direct consequence of every choice you make: who you suspect, what evidence you believe, and what methods you use. The game offers several unique endings — will you triumphantly uncover the conspiracy or encounter the unthinkable? A dissatisfying ending is not the end, but a reason to start over and find another way to the truth.
