Psycho-Sleuth is a mystery game where cognitive disorders distort the rules of murder. 13 players, each with a strange condition — like “no lying,” “no left side,” or “no faces” — are trapped in a deadly game. These disorders are contagious, and the killer hides behind abnormal logic.

Game Description

Join our Discord community!➡️➡️➡️➡️➡️ ══════════════════════════════════════════ Psycho-Sleuth is a mystery deduction game that fuses classic whodunit elements with cognitive distortion mechanics. In this deadly game of "kill without being caught," every murder is reshaped through the lens of bizarre mental disorders. Logic twists, truth warps—only your reasoning can restore order. A Twisted Trial of God A mysterious cult named Li has seized control of the world. Their cruel trial is simple: commit murder without being exposed, and you shall ascend to godhood. 13 "Afflicted Ones" are summoned—individuals burdened with rare cognitive disorders that spread their warped perceptions to others, creating murder scenes that defy reason: OCD forces absolute truth—no one can lie Spatial neglect erases evidence from the left side of reality Prosopagnosia blurs every face into anonymity Can you untangle these cognitive illusions and expose the true mastermind? Intense and Fast-Paced Debate Battles Enter Debate Mode, where you'll rapidly judge every statement: Will you accept their words, or strike back with the right clue? Every battle tests your logic, instincts, and time management. Murders Twisted by Cognitive Disorders In Psycho-Sleuth, crime scenes are not what they seem. Witness bodies without faces, missing evidence, and spaces erased by perception. That corpse with severed limbs—was it murder? Or did they fall victim to their own "Alien Limb Syndrome"? 13 Unique Afflicted Characters Each character bears a distinct disorder and a unique "Afflicted Power." Understanding their minds is key to uncovering their crimes and motives. Immersive Live2D Animations & Stunning CG Detailed Live2D portraits bring every emotional nuance to life, while high-quality CG sets the stage for tense interrogations and shocking punishments. When the culprit is revealed, they will face a punishment shaped by their own cognitive disorder. In a world consumed by distorted perceptions, will you uncover the real truth? Psycho-Sleuth invites you to challenge twisted logic and confront pathological reality.
