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. 

Fellow Thieves,

We’re just under two weeks away from the Triple-I Initiative on 9th April!. At the show, we’ll be lifting the veil on Thick as Thieves’ brand-new gameplay trailer alongside some other well-guarded secrets. But before all that, we want to share an update.

When we first revealed Thick as Thieves we intended to focus on PvPvE gameplay. 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.

This sharpened focus has allowed us to double down on what makes Thick as Thieves truly special – dynamic stealth gameplay. We’re already seeing how this has strengthened the moment-to-moment action, whether you’re playing solo or with a partner in co-op.  We’ve had some fantastic moments while testing the game. Now we’re putting all our energy into making things even better as we build up to launch.

We’re so excited show you more of Thick as Thieves at the Triple-I Initiative. In the meantime, come and chat all things Thick as Thieves with us in our official Discord server.

Your partners in crime,

OtherSide Entertainment
