Batman - Rise of Sin Tzu 1.3.2

The bulk of the game has the player battling groups of enemies in the style of games like Battletoads and Double Dragon.
The story mode, which forms the bulk of the game, can be played either alone or co-operatively, and rewards players for completing levels not only by continuing the story, but also with an upgrades system. This allows players to purchase new moves for their character and other game bonuses. There is also a challenge mode in which players (either cooperatively or competitively) take on groups of thugs without a storyline.
The game is played under a time limit, and features co-operative play. It also has 4 different difficulty levels: 'Easy', 'Medium', 'Hard', and 'Dark Knight'
