OtherSide was founded in 2013 by Paul Neurath, a veteran of "Thief" and "System Shock 2," with "Deus Ex" creator Warren Spector joining in 2016. These two developers shaped the stealth genre as we know it today, giving "Thick as Thieves" a solid foundation.
The new trailer showcases the fictional Scottish town 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 equipment pieces, and multiple difficulty settings that alter the layout of each level.
"Thick as Thieves" has evolved since its reveal at The Game Awards in December 2024. Originally conceived as a PvPvE game, it now arrives as a solo or two-player experience without conflict. OtherSide announced the change on Steam on April 2, 2026.
"As development progressed and the world of Kilcairn came to life, we found ourselves having more fun with solo and cooperative play. So we made the decision we believe is right for the game. 'Thick as Thieves' is now focused on cooperative and single-player gameplay. This sharpened focus has allowed us to double down on what makes 'Thick as Thieves' truly special: dynamic stealth gameplay."
Several game testers and fans expressed disappointment over the removal of PvP. However, one developer mentioned that "PvPvE could come later."
There is also no information on console versions. "Thick as Thieves" was announced for PC, PlayStation 5, and Xbox Series X/S, but the latest news suggests it will first (if not only) release on Steam. The details remain somewhat uncertain at the moment.
