An amazing game! But damage to the Joker ...

This game is a marvel! It is a perfect blend of action, infiltration, exploration, with the right amount of fun, humor and diversity into a gaming experience extraordinary. The graphics are great, the fights are very fluid, maneuverability is perfect, and everything is served with a good script. The Batman fan will be happy, the comics universe was very well respected by the game designers who have made a real tribute to the Dark Knight universe.
There is only one downside, and size as it is squarely false advertising: contrary to what the cover says, you do not play as the Joker in Challenge mode, because it is necessary for this to download a DLC pack on PlayStation Network, and this pack was withdrawn from the European PSN. Simply shameful!
