Set in an alternate history metropolis where technology clashes with magic, Thick As Thieves immerses you in a complex, detailed world of glittering wealth, a thriving criminal underclass, and a touch of magic.

As the upper class amasses wealth and power while the lower class struggles to survive, you weave your way through both worlds, pursuing treasure and glory with stealth and cunning.  

Players engage in a unique competitive multiplayer experience, where infiltration, theft, and escape drive success. The game rewards clever tactics, planning, and improvisation. 

Thick As Thieves exemplifies OtherSide's commitment to player-driven agency, creating an experience where each playstyle can unfold uniquely in a vibrant world. 

OtherSide Entertainment and Megabit Publishing confirmed that Thick as Thieves will be priced at $4.99/€4.99/£4.99 when it launches on PC (Steam) on May 20, 2026.

Alongside the pricing announcement, the studio also revealed future plans for Thick as Thieves with this release acting as an introductory campaign, with the intention of expanding the setting and its stories across future content. This decision reflects the team’s desire to bring players into the world sooner, and to give the team the flexibility to develop additional content informed by how players engage with the game. 

Paul Neurath, CEO of OtherSide Entertainment says, “Kilcairn is an early 1900’s alternative history city setting we've always wanted to explore beyond a single story. Releasing this introductory campaign gets players into the world of Thick as Thieves and gives them a meaty taste of a world worth returning to.”

This introductory campaign will feature 16 missions set across 2 dynamic replayable maps along with 6 pieces of gear to unlock across a campaign that runs at least four hours.

Additionally, a new developer walkthrough explores the stealth systems at the core of the game and offers a closer look at some of Kilcairn’s most mysterious corners.

Key Features: 

• Innovative Stealth Action – Classic stealth taken to new heights as players improvise to find creative solutions to pull off audacious heists in a dynamic world that is out to stop them.
