Psycho-Sleuth joins Steam Next Fest — A mystery where reality bends with every mind
Taiwanese indie studio PHOSEPO Inc. has announced that its psychological detective adventure Psycho-Sleuth is now featured in Steam Next Fest (October 13–20, PST), with a fully playable demo available worldwide.
Psycho-Sleuth combines classic deduction gameplay with the concept of “cognitive distortion.” Each of the 13 “Afflicted” characters suffers from a unique mental disorder that literally changes what players can see, hear, and deduce.
When a witness cannot perceive the left side of the world or cannot recognize faces how can you still uncover the truth?
About the game
Psycho-Sleuth is a psychological mystery visual novel where thirteen individuals with cognitive disorders are trapped in a deadly game. Each murder is distorted by the killer’s mental condition—faces vanish, evidence contradicts itself, and reality fractures.
Your own perception becomes compromised as Disease Abilities alter your vision and controls in real-time. Enter Debate Mode battles, identify contradictions, and navigate through the twisted perceptions of the Afflicted.
In a world where cognitive disorders become weapons, can you expose the killer hiding within chaos?
