Their distorted perceptions can spread to others, making it even harder to separate facts from fiction. Somewhere among them, a murderer is hiding behind a web of twisted logic.
A Deadly Game With a Twisted Goal
The world has fallen under the control of a mysterious cult known as “Li.” Its members have created a brutal test with one simple rule: kill someone without getting caught, and earn the right to become a god.
Thirteen people, called the “Afflicted Ones,” are forced to take part. Each has a rare cognitive disorder that affects how they understand the world. Even worse, these conditions can influence the perceptions of those around them, creating crime scenes that seem to make no sense.
Some examples include:
- OCD: Creates a world where everyone is forced to tell the truth, making lies impossible.
- Spatial Neglect: Causes people to overlook everything on the left side of their surroundings, including important evidence.
- Prosopagnosia: Makes recognizing faces impossible, leaving everyone looking like a stranger.
With so many unusual conditions at play, finding the real killer takes more than simply collecting clues. Every detail needs a closer look, and every assumption could lead in the wrong direction in Psycho-Sleuth.
Fast-Paced Debates and Unusual Murder Mysteries
The investigation becomes especially intense during Debate Mode. Here, every statement demands a quick decision. Accept what someone says, or challenge their argument with the correct piece of evidence at Psycho-Sleuth.
These encounters put reasoning skills, instincts, and time management to the test. There is little room to hesitate when the truth is buried beneath conflicting accounts and distorted memories.
The murder investigations are just as unpredictable. Crime scenes can contain faceless bodies, seemingly vanished evidence, or entire sections of reality that characters fail to perceive.
Even the appearance of a victim can raise unexpected questions. For example, a body with missing limbs might initially look like the result of a brutal murder. But could Alien Limb Syndrome be responsible instead? Situations like these make every investigation feel a little different.
