GTA IV Episode 1: The Lost and Damned
In this episode, you will no longer be playing as Niko Bellic. Instead, you'll control Johnny Klebitz, a member of Liberty City biker gang The Lost. Johnny has a very different background to Niko, and as such has a completely different character. Niko won't be completely absent from this episode though, it has been mentioned that he does have a small part somewhere. The episode's storyline is said to "show you a different side of Liberty City".
The story is not directly impacted by decisions you took in the main game, but tons of details and mysteries from the main story get explained, so it will add a lot of color to the main story.- Dan Houser, November 2008
