Best Detective and Mystery Games on Steam

A good detective game trusts you to think. Instead of highlighting the clue in yellow paint and walking you to the answer, it hands you a stack of contradictory evidence and waits. The games below cover the whole spread of that idea: logbook deduction puzzles where you name every face on a doomed ship, open-city simulations where you can follow the wrong suspect for an hour, and dialogue-driven investigations where the hardest question is what you are willing to write in the final report. Their achievement lists tend to be honest about it too, rewarding solving the case cleanly rather than simply reaching the credits.

1

Return of the Obra Dinn

You board an empty ship with a pocket watch that replays the moment of each death, then reason out the identity and fate of all sixty souls aboard. Deduction with no hint system and no hand-holding, and it only confirms answers three at a time.

2

Disco Elysium - The Final Cut

A murder investigation where the real case is the wreck of a detective who cannot remember his own name. Astonishing writing, and your own competing thoughts argue with you as skill checks.

3

The Case of the Golden Idol

A dozen strange deaths told in single frozen scenes, with the story assembled by dragging words into blanks. Pure logic, almost no text you did not deduce yourself, and a slow-burning conspiracy underneath.

4

L.A. Noire

Post-war Los Angeles rebuilt as an open city, with interrogations driven by remarkably detailed facial capture. Reading a suspect and choosing when to press is the whole game.

5

The Roottrees are Dead

Reconstruct an entire family tree from a mid-nineties search engine, newspaper scans and photographs. It captures the feel of genuine archival research better than almost anything else here.

6

Paradise Killer

An open-world murder investigation on a doomed island paradise where you gather evidence freely and then personally decide who stands trial. You can accuse anyone at any point, which makes certainty feel earned.

7

AI: The Somnium Files

A serial killer case that alternates sharp adventure-game investigation with surreal dream sequences inside suspects minds. Tonally all over the place in the best way, and the branching timelines reward replays.

8

Her Story

Nothing but a police database of video interview clips and a search box. You type words, watch what comes back, and slowly work out what actually happened without the game ever telling you.

9

Sherlock Holmes Chapter One

A young Holmes on a Mediterranean island, with an investigation system that will happily let you convict the wrong person and move on. Fewer guardrails than most licensed detective games.

Shadows of Doubt

A procedurally generated noir city where every apartment can be entered and every citizen has a routine, a job and fingerprints. Cases are never scripted, so no two investigations resolve the same way.
