A good game in the logical continuation of Arkham Asylum

The game is excellent, it contains all the elements that the success of the first, plus: A summary of the purpose and history during loading phases, a challenge game / puzzle much more successful (It interacts with mystery man!), shortcut buttons to access the gadgets, with phases of play Catwoman, and well-crafted side missions.
What we find in the game: A great story, cool graphics, a nod in every way to the Batman universe, a black knight as ever, a VF more convincing.
Less compared to the previous opus: The universe is much more "open" (A primary mission which move in the city of Arkham City, and side missions that are found and filled by walking of the said city), which lost in containment atmosphere of the first game.
