Thick as Thieves, the magical heist game from a crew of stealth legends at OtherSide Entertainment, is coming to Steam on May 20. OtherSide and publisher Megabit Entertainment announced the release date in a new gameplay trailer during today’s Triple-i Initiative showcase (which was packed with cool indie games, as always).

OtherSide was founded by Thief and System Shock 2 veteran Paul Neurath in 2013, and Deus Ex creator Warren Spector joined in 2016. These are two of the developers who shaped the stealth genre as we know it, so Thick as Thieves has a solid foundation. The new trailer showcases the game’s fictional Scottish city of Kilcairn, where magic and technology clash against a backdrop of 1910s music and architecture. At launch, Thick as Thieves will feature two thieves, two maps, 16 contracts, six unique pieces of gear and multiple difficulty settings, which alter the layout of each level.

Thick as Thieves has evolved since its introduction at The Game Awards in December 2024. It was originally pitched as a PvPvE game, but it’s landing as a solo or two-player experience, with no player-on-player brawls. OtherSide announced the pivot on Steam on April 2, 2026:

“As development progressed and the world of Kilcairn has come to life, we found that we were having more fun with solo and co-op play. So, we’ve taken a decision we feel is right for the game: Thick as Thieves is now focused on two-player co-op and single player. This sharpened focus has allowed us to double down on what makes Thick as Thieves truly special — dynamic stealth gameplay.”

A handful of playtesters and early fans expressed their disappointment at the removal of PvP. A developer responded to one question with, “PvPvE may come further down the line.”

There’s also no word on the console versions of the game. Thick as Thieves was announced for PC, PlayStation 5 and Xbox Series X/S, but today’s news suggests it’s coming to Steam first (if not only). Details are a bit up in the air at the moment, but hey, at least it’s on-brand for the developers of a stealth game to be sneaky.
