When developer OtherSide Entertainment revealed the next game from Warren Spector, best known for his work on Deus Ex and Ultima Underworld, the game was pitched as a new PvPvE stealth-action multiplayer game. But that was back in 2024, and the developer has since made a substantial change to that project, Thick as Thieves. The studio has reworked its stealth game to focus on solo and cooperative play.
“When we first revealed Thick as Thieves we intended to focus on PvPvE gameplay,” the studio said in an update posted to Steam. “However, 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.”
