Rockstar has finally officially announced details on the Xbox 360 exclusive GTA IV DLC. Titled Lost and Damned, the story centers not around Niko, but a new character named Johnny Klebitz.  Johnny is a member of the Liberty City biker gang, The Lost.  You may have heard about them on the many different radio station Liberty City has to offer.  Rockstar promises that the new content will add hours of gameplay, not just extras.

"Johnny is a very different character than Niko, with a very different background," says Dan Houser, vice president of creative development for Rockstar Games. "I can't go into too much detail on the story, because we try not to give away too much plot before the game is released. But I can say that the story will show you a different side of Liberty City."

It will be nice to play through Liberty City as a different character other than Niko.  I'm looking forward to it.  No price has been set yet, but I'm guessing about the same as the bigger name games map pack releases. We'll find out more as we get closer to February 17th.
