Dupery: A Game of Solo Deduction has officially launched on Steam with a release date of October 15, 2026. Developed by Gilded Rune Games and published by Yogscast Games and GamerSky Games, the game is a solo deduction roguelite set in a noir city controlled by a criminal syndicate. Check the Steam for the original details.

Players take on the role of a detective tasked with investigating 175+ unique roles across three distinct regions, each with its own mechanics and criminal syndicate. The game emphasizes strategic deduction, where players must arrest syndicate members while maintaining a reputation meter that can be lost if wrongful arrests occur.

Each region presents procedurally generated cases that require players to cross-reference clues, identify lies, and make critical decisions. The game includes four role categories—Innocent, Meddler, Underling, and Traitor—where Underlings and Traitors lie, and even well-meaning characters may be compromised.

To progress, players must balance arresting evil roles to increase their reputation while avoiding wrongful arrests that could lead to being fired. Completing cases in each region unlocks new tiers of roles and quirks, culminating in a final confrontation against the syndicate's mastermind.

The game features a notation toolkit for players to build in-game crime boards using strings, pins, and pen. It supports multiple languages, including English, Japanese, Korean, Simplified Chinese, Traditional Chinese, French, German, and Spanish, making it accessible to a global audience.

Dupery offers a 20% discount for the first month, with the standard price of R$ 44.99 discounted to R$ 35.99. The game is available on Steam and includes features like Steam Achievements, Cloud Stats, and Family Sharing.

The core attraction of Dupery is deduction rather than reflex combat. Its Steam description presents a roguelite mystery structure with a large pool of possible roles, changing cases and a noir setting. Because individual sessions can vary, clues and character behavior matter more than learning one universal answer. A player who enjoys working through competing explanations may find that premise appealing, while someone seeking a linear detective novel should investigate how much randomness and repetition the game actually contains.

Its advertised set of more than 175 roles suggests substantial variety, but role count alone does not establish the number of meaningful outcomes. Similarly, three regions and a reputation system can influence the shape of an investigation without guaranteeing that every run feels different. Those are useful distinctions when interpreting a store description: the quantity of systems tells buyers what the developer intends, while independent feedback and demonstrated gameplay show whether the systems work together coherently.

Before purchase, readers can use the official Steam listing to check the confirmed release date of October 15, 2026, current supported languages, input controls and system requirements. It is also worth checking recent developer updates for balancing changes or accessibility options since release. This article describes the published premise and store information, not a first-hand review or a promise about the difficulty of every generated case.
