Imagine a world where the evidence vanishes if you look left. Where every face is a stranger’s. Where nobody can tell a lie — and that makes everything more dangerous. Today, developer PHOSEPO alongside publishers Thermite Games and Smilegate STOVE releases Psycho-Sleuth — a psychological mystery where the rules of reality itself are the killer’s weapon — on PC via Steam, STOVE, and Epic Games Store.
This isn’t just another whodunit. It’s a game where the very way you see, hear, and understand the world is twisted, broken, and infected — and only your wits can stitch it back together.
THE TRIAL OF THE AFFLICTED
A cult calling itself Li has seized control of reality. Their edict is unflinching: commit murder without being unmasked, and you shall ascend to godhood. Thirteen “Afflicted Ones” are gathered — each carrying a rare, potent cognitive disorder that doesn’t just affect them — it spreads, warping perception, rewriting testimony, and erasing facts from the world itself.
These aren’t just flavour text — they are the mechanics of murder:
- OCD / Absolute Truth — No one in this room can lie. Every statement is fact. And yet, someone is still dead. How?
- Spatial Neglect — The entire left half of existence ceases to register. Clues vanish in plain sight; bodies are halved; rooms are incomplete.
- Prosopagnosia — Faces dissolve into blurs. You can’t recognise your allies — or identify the killer.
- Alien Limb Syndrome — A hand moves of its own accord. Did the victim strike the blow themselves? Or was it guided?
Each disorder doesn’t just flavour the story — it reshapes the investigation. The killer wields these distortions actively, manipulating what you see and how you interact with the scene. The crime scene is never what it appears — and neither is the truth.
DEBATE MODE — REASON AGAINST MADNESS
When testimony warps and facts dissolve, you enter Debate Mode — the game’s pulse-quickening interrogation system. Here, you weigh every statement, spot the fractures in perception, and strike back with evidence that cuts through the fog. It’s not just about finding contradictions — it’s about understanding how someone’s mind is broken so you can find the truth beneath the distortion.
The game pushes beyond standard visual-novel fare: distortions can affect your controls, your interface, and your understanding of the timeline. You aren’t just solving a puzzle — you’re fighting a psychological infection in real time.
A WORLD BREATHING MADNESS
Psycho-Sleuth delivers a staggering volume of crafted narrative:
- 500,000+ characters of branching script
- Full voice acting across key scenes
- 40+ high-quality CGs and dozens of 3D environments
- Live2D animations that let you read the flicker of fear, defiance, or deceit in every portrait
- 50+ original music tracks scoring the descent into chaos
Every character is fully realised, with their own motives, fears, and unique “Afflicted Power” — and their punishment, when judgement falls, is shaped by their own disorder. No two runs are identical; choices ripple through the cast, and multiple endings await — some revealing truths darker than the lies you started with.
AVAILABLE NOW — WHERE TO PLAY
Psycho-Sleuth is out today, 5 November 2026, across three major PC platforms:

FINAL THOUGHTS
Psycho-Sleuth doesn’t just ask “who did it?” — it asks “can you even trust the question?” By weaving real cognitive conditions into core gameplay, PHOSEPO and team have crafted something genuinely singular: a mystery that attacks your perception as well as your logic. It’s tense, it’s unsettling, and it’s deeply, thrillingly clever.
If you’ve ever wanted a detective story where the hardest clue is believing your own eyes — this is your game.
The truth is contagious. Don’t catch the wrong one.
