Warner Bros. Interactive Entertainment and DC Entertainment have unleashed the new Batman: Arkham City trailer featuring the content from the Nightwing Bundle Pack that is set to be available from November 1st on Xbox Live Marketplace and PlayStation Network. Yes that's right, although you have already laid down a considerable amount of money for Arkham City, you are already being tempted to download load additional add-ons. The Nightwing Bundle Pack trailer features all of Nightwing's athletic abilities and skull-crushing arsenals that will leave Gotham city's most dangerous thugs on the floor begging for mercy. The pack itself allows Nightwing to be playable in all challenge maps from the game as well as Wayne Manor and Main Hall add-ons. Watch the trailer below; The Nightwing Bundle Pack will set you back 560 Microsoft Points or $6.99 on the PlayStation Network. Similarly, the Robin Bundle Pack will be the same price when that is released on November 22nd but everyone knows Nightwing is cooler than Robin. Batman: Arkham City is of course out now (our 5 star review HERE) for the Xbox 360 and PlayStation 3 with the PC version coming November 15.
