Thick as Thieves is launching with a smaller price tag than its Warren Spector pedigree might suggest. OtherSide Entertainment's stealth heist game is set to arrive on Steam on May 20 for $4.99, £4.99 and €4.99.

The Steam listing describes Thick as Thieves as a short-session stealth-action game playable solo or in online co-op. Players take on heists in Kilcairn, an alternate-history Scottish city where early technology and magic sit side by side.

That low launch price comes with an important caveat. This first version is being framed as an introductory campaign, with 16 missions across two dynamic, replayable maps. It also includes two playable thieves, six pieces of gear and an expected campaign length of at least four hours.

A smaller launch after a design shift

Thick as Thieves has already changed shape since its first reveal. The project was originally announced as a PvPvE stealth game, but OtherSide later moved away from competitive multiplayer and refocused it around solo play and two-player co-op.

The core pitch is still about slipping through a guarded city, using gadgets and stealth to rob targets without getting caught. The Steam page says security layouts and guard setups can shift as difficulty rises, which is where the studio is leaning on replayability to stretch the compact launch package.

OtherSide said it wanted 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." The studio also said it plans to expand "the setting and its stories across future content," although it has not clarified whether later content will be free or paid.

The game is notable partly because of who is behind it. Spector and OtherSide co-founder Paul Neurath are closely tied to the Thief lineage, with the Steam page highlighting Spector's work as studio director on Deus Ex and Thief: Deadly Shadows, plus Neurath's executive producer credits on Thief: The Dark Project and Thief: The Metal Age.

For players who were curious about Thick as Thieves but unsure about its post-PvP direction, the $4.99 launch price makes the first campaign an unusually low-risk test of OtherSide's new stealth format.
