USAToday has gotten details on the new GTA IV DLC, it will include a story revolving around a new character. The release date is Febuary 17, 2009. No pricing information is given:
GTA IV, which was released in April for the Xbox 360 and Sony PlayStation 3, focused on former Eastern European soldier Niko Bellic and his escalating life of crime in the boroughs of Liberty City. This new episode, available Feb. 17 via download exclusively for those who own the Xbox 360 version (no price yet), stars Johnny Klebitz, a member of Liberty City biker gang The Lost.
“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.”
