From the padded cells of Arkham Asylum to the mean streets of Crime Alley, one truth is whispered wherever evil Gotham City belongs to the Batman.

Until now!

The crimelord formerly known as the Penguin is now Mayor Oswald Cobblepot -- elected to be Gotham's leader by promising to outlaw vigilantes and villains alike. The immortal mastermind Ra's al Ghul has ordered an invasion of assassins - not to destroy the Dark Knight, but to eliminate his enemies…permanently. And a two-bit hood called the Black Mask is forming a deadly new masked mob.

Outlawed. Outnumbered. On the run. Batman's greatest battle for the soul of Gotham City is about to begin!
