Warner Bros. Interactive and DC confirmed the rumors that Nightwing will be appearing in Batman: Arkham City. He'll be the focus of a downloadable content pack arriving on November 1st.
Nightwing is a costumed vigilante like Batman. In fact, he learned his trade from Batman. His real name is Dick Grayson and he was the first Robin. After coming of age, he struck out on his own.
In Arkham City's Nightwing Bundle Pack, Nightwing will have his own unique set of gadgets and special moves. He can be played in all challenges maps included with the full game, as well as two new DLC maps, called Wayne Manor and Main Hall. Also included in the DLC is an Animated Series Nightwing character skin.
WB and DC had some news about the current Robin, as well. It seems the Robin DLC, which enables players to play the Boy Wonder in challenge maps and also adds two maps, will be released to the public. The DLC, available to select pre-order customers on launch, will be available to the public on November 22nd.
You'll have to pay for the privilege to be Robin or Nightwing, though. Each downloadable content pack will cost $7, or 560 MS Points.
Arkham City will be released on October 18th in North America and on the 21st in Europe.
