Gilded Rune Games and Yogscast Games are bringing deception, procedural mysteries, and dangerous accusations to PC and Mac.
Everyone is suspicious.
Nobody is telling the whole truth.
And somehow, you’re the one responsible for figuring out what the hell is going on.
Welcome to Dupery: A Game of Solo Deduction.
Developer Gilded Rune Games and publisher Yogscast Games are launching the detective roguelite on October 15, 2026, for PC and Mac via Steam.
The game takes the tension of social deduction experiences and reimagines it as a single-player investigation adventure.
Instead of trying to identify the liar among your friends, you’ll investigate procedurally generated cases filled with conflicting stories, suspicious characters, and potentially disastrous accusations.
And unlike your average group chat argument, accusing the wrong person actually has consequences.
Social Deduction Without the Social Pressure
Dupery places players in the role of a lone detective investigating a mysterious criminal syndicate.
Each case presents a collection of suspects, statements, and clues.
Your job is to examine the available information, identify contradictions, and determine who is telling the truth.
The twist is that cases are procedurally generated, creating different combinations of suspects and circumstances across repeated playthroughs.
That means players can’t simply memorize the answers.
They’ll need to understand the game’s underlying logic and apply it to each new investigation.
Your Reputation Is on the Line
Making the correct arrest is only part of the challenge.
Players must also protect their professional reputation.
Wrongful arrests can damage their standing, and too many mistakes can bring their detective career to an abrupt end.
That adds a layer of pressure to every accusation.
You might feel certain that a suspect is lying.
But are you certain enough to risk your career?
Dupery is essentially asking players to stop making wild accusations and actually read the evidence.
A concept the internet could probably benefit from.
More Than 175 Roles and Three Regions
The game features more than 175 handcrafted character roles and three distinct regions.
Each region introduces its own mechanics and challenges.
Players can also unlock and experiment with quirks and modifiers between investigations, adding roguelike progression to the deduction formula.
These systems are designed to make each run feel different.
Rather than solving a fixed collection of mysteries, players gradually develop strategies for interpreting new situations.
Build Your Own Investigation Board
Dupery includes an in-game detective toolkit featuring notes, pins, and connecting strings.
Players can organize clues and map relationships between suspects as they investigate the criminal organization.
It’s a familiar visual language for anyone who enjoys detective fiction.
Except now you get to construct the conspiracy board yourself.
And unlike the person with 47 red strings connecting newspaper clippings in a crime drama, you’re actually supposed to do this.
Dupery Release Date and Launch Discount
Dupery: A Game of Solo Deduction launches October 15, 2026, on PC and Mac through Steam.
The developers are celebrating with a 20% introductory discount for a limited time.
Players can also watch the official launch trailer for a closer look at the game’s investigation systems.
A Fresh Twist on Detective Games
Dupery’s most interesting idea is taking the uncertainty of multiplayer social deduction and turning it into a structured single-player experience.
The combination of procedural cases, character roles, reputation management, and roguelike progression could make it particularly appealing to fans of logic puzzles and mystery games.
There’s something deeply satisfying about catching a contradiction and realizing you’ve finally cracked a case.
Of course, there’s also something deeply embarrassing about confidently arresting the wrong person.
We suspect Dupery will provide plenty of both.
