If you enjoy action / adventure games, you'll be pleased. If you're a Batman's fan, it will blow your mind.
The graphics are well polished, the game-play difficulty is reasonable, with a decent learning curve, the combat is fluid and the use of the source material was adequate, the voice acting is well done, giving birth to a storyline that makes you feel, indeed, as the Dark Knight himself.
The story begins with Batman bringing the Joker to the Arkhan Asylum, but during entrance of this notorious inmate, he manages to break loose, revealing there and than that his imprisoning was part of a plan to take over the asylum.
From this point on, it's up to the player to chase the Joker and reclaim Arkhan. In the long run, you'll have to face some well known enemies, like Harlequin, Killer Croc and Poison Ivy.
There are also, a total of sixteen challenges (eight combat and eight stealth missions) that will keep you entertained long after you've finished the story mode.
One of the best games of 2009.
