For those who have played the game, you may have spotted Nightwing wondering around the rooftops of Arkham City as a side quest. The trophy and achievement list already leaked the fact that Nightwing was quickly approaching as a playable character in the game.

A new trailer released today shows footage of Nightwing and the unique agile martial arts style he is bringing to the game. In addition he has two electric sticks known as the Escrima Sticks which bring with them new attacks and powers. Furthermore Nightwing will have access to wrist darts and other ranged weaponry.

The DLC pack will feature two bonus challenge maps, Wayne Manor and Main Hall and a Batman Animated Series clothes Skin. The pack will be released November 1st USA (2nd in the EU) at which time I believe the Robin DLC may also be released featuring similar content. No word on the pricing just yet but expect more content in the near future as all the pre order bonuses should eventually become available for download including Joker carnival maps, Penguin Iceberg Lounge maps and all of the various preorder clothes skins for Batman.
