Thick as Thieves: new stealth game from Warren Spector is on the way

The stealth game Thick as Thieves, developed by OtherSide Entertainment and designed by legendary creator Warren Spector, is getting closer to release. Set in the alternate 1910s Scottish metropolis of Kilcairn, the game will be available on May 20, 2026 for a strikingly low price of five dollars. With a focus on both single-player and co-op gameplay, Thick as Thieves aims to offer a unique experience for fans of the genre.

Game concept and gameplay

Thick as Thieves puts players in the role of a thief who must rely on stealth and strategic thinking to navigate the streets of Kilcairn. The game blends magic and technology, giving players multiple ways to tackle their objectives. Players will need to adapt to the challenges ahead, from steampunk surveillance to elusive security guards.

At launch, the game will feature an "introductory campaign" with 16 missions spread across two dynamic, replayable maps. With an expected playtime of at least four hours and packed with action and strategy, the campaign is designed to hook players and lead them into future content.

Development history and changes

Originally announced in 2024, Thick as Thieves has evolved in terms of gameplay. The developers at OtherSide Entertainment have said they are moving away from PvPvE in favor of a more focused single-player and co-op experience. For the team, playing together was simply more fun, and the change is expected to strengthen the game’s pace and action.

The city of Kilcairn

Kilcairn serves as the central location for Thick as Thieves and is designed as a lively, intriguing city that provides a rich backdrop for the gameplay. This alternate 1910s setting opens up plenty of possibilities for storytelling and exploration. With so many different environments and challenges, the city invites players to test their stealth skills and uncover the secrets Kilcairn is hiding.

With a low entry price and dynamic gameplay, Thick as Thieves is aiming at a broad audience that enjoys stealth games and co-op experiences. Warren Spector’s involvement in the project has raised expectations, especially given his past successes in the games industry. The decision to drop PvPvE in favor of a stronger focus on cooperation could give the stealth genre a fresh twist. As launch day approaches, players are eager to return to Kilcairn and join the Thieves Guild.
