Press release:
May 7th 2026, Bristol, UK | Yogscast Games and Gilded Rune Games have today announced Dupery – a single-player investigation roguelite which takes the thrill of social deduction games into a tightly designed puzzle of lies, contradictions and deceit for solo players.

A terrible syndicate has infiltrated society, so players explore cases, listen to what the citizens have to say and use that information to root out the wrong ‘uns. Over the course of their investigations, detectives must gather clues, question suspects and piece together conflicting information to identify hidden roles within a criminal syndicate.

The problem? Not everything revealed is true.

Each run is made up of procedurally-generated cases, spread across multiple regions, each with its own mechanics, rules, and quirks. Through Colombo-like deduction, players must build an understanding of how different roles behave, learning to spot inconsistencies, rule out impossibilities and slowly untangle what’s really going on.

Runs culminate in a final deduction challenge, where players must correctly identify and eliminate the syndicate leader based on everything they’ve learned. Every mistake along the way carries consequences, meaning progress is always balanced against risk.

“I only got five GSCEs,” says Simon Byron, Managing Director, Yogscast Games,

“but there have been runs in Dupery which have made me feel like the cleverest man on the planet. It’s a brilliant twist on social deduction without the need to organise groups of players, yet a game which feels perfect for both playing solo or collaboratively in groups.”

Developed by Bristol-based team Gilded Rune Games, Dupery has already seen strong early engagement, with thousands of demo players and extremely positive feedback highlighting its depth, replayability and satisfying deduction systems.

“We’ve loved getting Dupery to where it is,” adds Matthew Brebner, Developer at Gilded Rune Games.

“It really makes you feel like a true detective, without having to do all the paperwork, of course, and we’re excited to be working with Yogscast Games to bring it to a huge global audience. ”

Dupery is set to launch on PC later this year, with a playable demo available now on Steam.

About Yogscast Games
Yogscast Games was established in 2017, with a simple goal: to work with independent teams to develop and publish games that are as fun to watch as they are to play.

About Gilded Rune Games
Gilded Rune Games is a Bristol based video game company. Having met several years prior during university, the 3 wannabe game developers Matt, Luke, and Lydia were brought together by their shared love of games, especially TTRPG’s. Nothing tests cooperative problem solving skills quite like imminent fictional death after all. After their studies, the trio formed the company launched by a strong desire to not only create games, but bring their own ideas to life.

Since their formation in 2022, Gilded Rune Games has released four games on Steam, exploring a myriad of genres with each release. Their upcoming game, Dupery, revolves around the deep mechanics and silly story elements that brought them together in the first place, which they hope you enjoy!
