About the game

What you do in a play session

Prepare for chaos in KeyForge: Mass Mutation! This fourth expansion for the unique card game introduces over 200 brand-new cards, many featuring bizarre and unexpected versions of familiar creatures, all thanks to the mutagenic power of dark Æmber. Watch out for gigantic creatures that span two cards! And to top it all off, House Sanctum makes a triumphant return. It's the perfect time to dive into the fast-paced, frantic duels of KeyForge, where every deck is completely unique, randomly generated, and ready for battle. Each two-player starter set comes with two ready-to-play decks, mixing three of the most diverse Houses of the Crucible. Each of these decks has its own unique card combination and is unlike any other Archon Deck out there. Oh, and of course, you also get all the tokens needed to start playing with friends. In Mass Mutation, the objective remains the same: gather Æmber and forge three keys before your opponent. It's a wild race where you can either speed up your Æmber production or hinder your opponent with "take that" tactics. The first to forge their keys wins! With Ghost Galaxy now at the helm, the KeyForge experience continues to evolve, with new formats and game modes emerging to keep the excitement going.
