It's the best superhero game I have played in a long time.
The gameplay is very innovative and simple at the same time. During combat pressing one button causes Batman to strike, and pressing another cause him to counter incoming attacks. The goal of this is for the player to try to keep the combo going to obtain more exp points. In addition, there is a great sense of progression in the game as new melee moves can be unlocked, and upgrades to Batman's gadgets can be purchased. The stealth aspect of gameplay involves Batman using the environment to quietly take down armed inmates. New enemies will appear as the story progresses, keeping the players on their toes.
Batman Arkham Asylum sets a new precedent for super hero video games. You do not have to be a fan of the Dark Knight to enjoy this game.
