Dupery is a single-player deduction roguelite scheduled to launch on Steam on October 15, 2026. At the time of the latest available listing information, the full game was not yet available, but a demo was listed. Its cases revolve around weighing clues and testimony, spotting deceptive characters, and deciding whom to arrest without letting your reputation fall too far.
What is Dupery?
Dupery is a solo detective game set in a noir city infiltrated by a criminal syndicate. You investigate cases, identify its members, and work toward uncovering the network’s leader. Although some characters lie or mislead, the game is designed for one player rather than as a multiplayer social-deduction party game.
Steam describes four character role categories: Innocent, Meddler, Underling, and Traitor. Roles can affect how much useful or misleading information a character provides. The listing’s role-count claim is inconsistent: some versions say “175+ roles,” while others say “over 200.” The exact total is therefore not established by the available listing text.

How does Dupery’s deduction gameplay work?
Each case places characters on a grid and asks you to compare their testimony with clues. You use the information to judge who is deceptive, then arrest suspects. Wrongful arrests damage your reputation; solving cases advances the campaign. The challenge is not simply finding a liar, but deciding whether the evidence is strong enough to act on without accumulating too many mistakes.

Track evidence on the crime board
The game includes an in-game detective board with strings, pins, and a pen for organizing clues and connections. It serves as a notation tool as you cross-reference what characters say with the evidence in a case.
Expect variation between cases
The Steam listing describes cases as procedurally generated, so their arrangements and information can vary. It also describes three regions or campaigns with distinct mechanics and roles, selectable roles between missions, and quirks and modifiers. A final confrontation is part of the listed campaign structure.
