Dupery is a single-player deduction roguelite planned to launch on Steam on October 15, 2026. You play a detective investigating a criminal syndicate: compare testimony and clues, decide who is lying, and make arrests without letting wrongful accusations ruin your reputation. Steam’s listing also includes a demo, though the full game was not yet available when the page was checked on October 12, 2026.
What is Dupery?
Dupery is a solo mystery game set in a noir city infiltrated by a criminal syndicate. Rather than relying on a group of players to bluff and interrogate one another, it presents a detective’s cases for one player to solve. The campaign leads toward uncovering the syndicate’s leader.

Steam describes four role categories: Innocent, Meddler, Underling, and Traitor. Characters may provide false, misleading, or incomplete information, so a suspicious statement is a clue to weigh—not proof on its own. Cases are arranged on a grid and procedurally generated, according to the store listing.

How does the deduction gameplay work?
Cross-check clues and testimony
Each case asks you to work out which characters are deceptive and how they fit into the larger criminal network. The challenge is to compare what people say with the other information available, including clues that may be partial or misleading.

Organize the case on a detective board
An in-game board provides strings, pins, and a pen for connecting evidence and keeping track of your reasoning. This makes note-taking part of the intended play: the goal is to build a case from relationships between clues, rather than simply select a suspect after a conversation.
Arrests carry a cost
Arresting the wrong person reduces reputation. Let it fall below the failure threshold and the case can end badly; solve cases to progress through the campaign. That creates a trade-off between acting on a plausible lead and waiting until the evidence is convincing enough.

What does the campaign include?
The Steam description outlines three regions or campaigns, each with distinct mechanics and roles, followed by a final confrontation. It also lists selectable roles between missions, quirks, and modifiers. Together with procedurally generated cases, those systems are intended to vary investigations and add roguelite progression.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsThe listing’s role total is inconsistent: retrieved versions have described both “175+ roles” and “over 200 roles.” The exact number is therefore not reliable enough to present as settled.

Who is Dupery for?
The clearest fit is someone who enjoys written-clue deduction, tracking relationships between suspects, and campaign progression, but wants to play alone. Its crime board and imperfect testimony point to deliberate evidence management. It is not presented as a multiplayer social-deduction party game, and the available listing does not establish how satisfying its systems feel in practice; the demo is the best way to judge that for yourself.
