Watch the launch trailer for Dupery HERE
Taking the high-stakes tension and satisfying "gotcha!" moments of social deduction games, Dupery brilliantly reimagines them into a single-player investigation roguelite.
Playing as a lone wolf detective up against a shadowy criminal syndicate, you must solve grid-based procedural cases where every suspect has something to say - but hardly anyone is telling the whole truth.
To solve a case, use clues provided by the characters and deduce whose stories are not quite checking out. But beware, detective, as not only are innocent lives on the line - so is your reputation. Too many wrongful arrests will lead to the end of your crime-solving career.
In Dupery, players can make use of quirks and modifiers between missions and an in-game investigation toolkit complete with strings, pins and notes to map out the criminal underworld and bring down the syndicate mastermind.
With over 175 handcrafted roles and three distinct regions, each with its own unique mechanics, no two cases play out the same way. Do you have what it takes, detective?
