About Psycho-Sleuth

Psycho-Sleuth - about the game
Psycho-Sleuth delivers a strategy adventure centered on mystery deduction, where murders unfold through cognitive disorders that warp logic and evidence. A cult called Li runs a deadly trial: thirteen Afflicted Ones must kill without detection to claim godhood, each wielding a unique disorder like OCD that bans lies or spatial neglect that hides left-side clues. Players unravel these twisted crime scenes, spotting illusions from prosopagnosia or Alien Limb Syndrome. Debate Mode sparks fast-paced clashes, demanding quick judgments on statements with the perfect clue to strike back. Live2D animations capture character emotions during interrogations, while CG depicts punishments tied to each disorder. Logic enthusiasts who thrive on time-pressured reasoning and perceptual puzzles will master this pathological showdown.

══════════════════════════════════════════

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.
