Batman: Arkham City Robin, Nightwing, and Skins DLC dated, priced

As we noted earlier, all pre-order "exclusive" DLC for Batman: Arkham City will be made available for purchase after release. GameStop has inadvertently confirmed this, revealing the dates and prices for three upcoming DLC packs. The first pack will be the Nightwing character pack, available on November 1st for $6.99 (560 Microsoft Points).

Nightwing will feature his own "unique gadgets and special moves," and is playable in all challenge maps in the game. The DLC includes two additional challenge maps: Wayne Manor and Main Hall. The pack also contains a bonus Animated Series Nightwing character skin.

The next release will be the Robin character pack, available on November 12th, also for $6.99. This add-on will be available for free with pre-orders at Best Buy.

The retailer has since taken the listings down, but not before the Arkham City forums (via CVG) spotted them. Since then, Warner Bros. has confirmed the dates for both the Robin and Nightwing DLC.

According to GameStop, the Skins pack will be available on December 6th for $4.99 (400 Microsoft Points). It's unclear what will be included in this DLC bundle, but the above image shows some of the possible outfits.

There are some other DLC plans still unaccounted for. Batman's Kevin Conroy promised that additional "episodes" starring the Bat would be available, and Catwoman is supposed to get an expansion pack as well.
