Gotham City Impostors is a multi-platform first person shooter downloadable game coming out in 2012. The game's premise centers around the conflict between the Batman's and the Joker's repective groups of imposters. Player VS player play is going to be where this game shines (I am not even sure if there is going to be single-player play modes). Up to twelve players (6 vs 6) will be able to take part in epicly destructive on-line battles. Players can completeley customize their characters and weapons insuring that 'you' will be unique.
