Batman: Rise of Sin Tzu — Like Batman, Batgirl, Robin and Nightwing, the player must fight groups of enemies. The story mode, which forms the bulk of the game, can be played independently or cooperatively, and the game rewards players for completing levels not only by continuing the story, but also through an upgrade system. This allows players to purchase new moves for their character and other in-game bonuses. There is also a challenge mode where players (either cooperatively or competitively) fight groups of thugs without a storyline.
