What Psycho-Sleuth is
A mystery visual novel from PHOSEPO, a Taiwanese studio, published by Thermite Games and Smilegate. You are dropped into a cult called Li — the Logic Church — which runs a contest called the Selection. Thirteen people are brought in, each carrying a different rare cognitive disorder, and each disorder is contagious: it leaks out of its owner and rewrites the room. One contestant is a killer. Your job is to reconstruct a scene where the evidence itself is lying.
The loop is fixed: a murder, an investigation into a space a disorder has quietly ruined, then a debate.
Out now, and what it costs
Steam lists 4 November 2026. The studio's own announcement says 5 November — the same launch from a different time zone. The game is $19.99, and it is 10% off for the first 14 days, so $17.99 today.
| Item | List price | Launch price |
|---|---|---|
| Base game | $19.99 | $17.99 (−10%) |
| Soundtrack | $6.99 | same window |
| Artbook | $8.99 | same window |
| Deluxe (all three) | $35.99 | $30.59 (−15%) |
No subscription and no currency. The bundle is the only place the discount passes 10%. The full price file has the day it ends.
The trial, in one paragraph
The Logic Church's rule is short: kill without being found out, and you ascend to godhood. Thirteen Afflicted are summoned, one takes the offer, and the rest become suspects, witnesses and obstacles. Each chapter is one round: a body, a corrupted scene, a debate. The disorders are the puzzle, not flavour. A suspect with spatial neglect cannot see the left half of a room, so a weapon on the left of the table never existed for them; a suspect who cannot recognise faces describes a room full of strangers. Working out which testimony is broken, and why, is the game.
Before you start
- Try the demo first. Two hours, free, still on Steam, now with extra cutscene clues added for launch.
- Expect about 20 hours by the studio's own estimate, assuming you read.
- Avoid the community hub in week one. Spoiler titles are already up.
- Voice acting is Japanese only. Five text languages, one audio track.
- Steam Deck is listed as Unsupported for graphics performance, despite the demo being advertised as Deck-compatible in 2025.
Straight answers
How long is it? About 20 hours, five chapters, one trial each.
Is there a demo? Yes, free, still up, covering the opening case.
Does my demo save carry over? PHOSEPO has not published a transfer path, and Chapter 1 was rebuilt for launch, so plan on a fresh start.
Is it gory? Bloody, displayed in full by default, with a Gore Display toggle if you stream.
