Batman: Arkham Asylum (Eidos, $59.99, for the Xbox 360, PlayStation 3) redefines superhero games in the same way The Dark Knight set the bar for comic book movies. For DC Comics fans, it's a must-buy, but it's hugely entertaining even if you aren't versed in the whole Batman mythology. Developer Rocksteady has breathed life into the Caped Crusader's universe with aplomb, tackling Gotham and its villainous underbelly with the same fresh - yet faithful - approach Chris Nolan did when rebooting the Batman movie franchise. The result is not only one of the best comic book games ever made, but it's also one of the best games you're likely to play this year. Fans will relish the chance to take on familiar Batman foes like Harley Quinn, Poison Ivy, Killer Croc and Scarecrow.
