Running off the AUGS engine, Shadow of the Bat offers unrivaled flexibility and player choice. Players can take the role of any hero in their roster in the game's 24 unique missions, all inspired by fan-favorite episodes. Likewise, even villains can be swapped out in every mission to change up the threats that players will face. In Shadow of the Bat, 1-4 players will take to the streets as Batman, Batgirl, Robin, Commissioner Gordon, and Catwoman, each with their own unique character abilities, skills, and custom dice. And they'll have to work together in order to take down the likes of Two-Face, The Penguin, Mr. Freeze, The Riddler, Scarecrow, Man-Bat, The Joker, and Harley Quinn. As with other AUGS games, villains can be controlled by the game itself for full co-op play, or by a 5th player. AUGS' modularity means that players can even create their own dream scenarios and teams, including bringing in elements from other AUGS products.
Launching alongside Shadow of the Bat is the Arkham Asylum expansion, which will add 13 more missions to play through, and an all-new game mode: Clayface mode. In Arkham Asylum players will explore the halls of the infamous psychiatric hospital as they tangle with Clayface, Poison Ivy, Jervis Tetch, The Ventriloquist, Killer Croc, Maxie Zeus, Lock-Up, Clock King, Baby Doll, and Hugo Strange. In Clayface mode, each hero will be given a card that will indicate if they are who they appear to be, or if they're actually Clayface in hiding. At any time, the Clayface player can reveal their true identity, transforming into the massive Clayface, and turn on their former friends!
Players will also have the option to expand their roster of heroes and villains with The New Batman Adventures character pack, containing Nightwing, Tim Drake as Robin, Calendar Girl, and Firefly. Story Packs for Mask of the Phantasm and Mystery of the Batwoman will also be available, adding new missions and characters–The Phantasm and Bruce Wayne in plain clothes, and Batwoman and Bane, respectively–that follow the films' stories.
