If you thought the Batman universe was dangerous enough, get ready to step into the darkest corridors of Arkham! This expansion for Batman: The Animated Series Adventures cranks up the tension, bringing 13 brand-new missions that will test the heroes' courage. Get your best contingency plan ready, because the villain lineup is heavy: prepare to face heavyweights like Poison Ivy, Killer Croc, Jervis Tetch, Hugo Strange, and many others who won't make it easy for you. The real star of the show, however, is the new Clayface mode, which is pure paranoia! In this mode, suspicion takes over the table: each hero receives a secret card indicating whether they are truly who they claim to be or if they are actually Clayface in disguise. Just imagine the tension of knowing that, at any moment, one of your allies could reveal their true form, transforming into the massive Clayface and turning the tide against the group! It's exactly the kind of twist that keeps everyone glued to the table, trying to uncover the imposter before it's too late. If you enjoy a cooperative experience with a touch of mystery and classic animated series action, this expansion is the perfect addition to turn your game nights into true Gotham adventures.
