The game features most of the best known superheroes from the DC Universe, including Superman, Batman, and Wonder Woman among others. Each level consists of two members of the Justice League battling a variety of villains and their henchmen. When the game is being played by a single player, the player can freely switch between playing as either of the two Justice League members at any time. In a two player game, the players can only switch which characters they control by mutual consent. There was another Justice League game in development from Midway Games that was canceled in 2004 but, according to Warner Bros., this game is unrelated to the current project.[9]
