Cryptozoic Entertainment, leading creator of board games, trading cards, and physical and digital collectibles, and Warner Bros. Consumer Products, on behalf of DC Entertainment, today announced the limited release of DC Spyfall at Gen Con, August 2-5, followed by a full retail release on August 8.
In this new iteration of the social deduction game Spyfall, 3-8 players take on the roles of DC’s greatest Super Heroes as they have a secret meeting at an iconic location, such as the Batcave, Daily Planet, or the Fortress of Solitude. The twist is that one of them is secretly The Joker in disguise. In the intense 8-minute rounds, the non-Joker players ask questions and give answers to deduce which one of them is the Clown Prince of Crime without giving away the location, while The Joker player tries to figure out the location before his or her identity is revealed.
