The first downloadable content for the Xbox 360 version of GTA IV will be available from 17th February, Rockstar has confirmed.

USA Today has reported the news following an interview with Rockstar boss, Dan Houser.

The first episode will be titled The Lost and Damned and will feature Johnny Klebitz, part of the Liberty City biker gang The Lost.

As for Niko, he's only set to have a small part in the new episode.

"Johnny is a very different character than Niko, with a very different background," said Houser.

"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."

How you chose to play the main game won't affect how The Lost and Damned will play out, but Houser did add that "tons of details and mysteries from the main story get explained [in the new episode], so it will add a lot of colour to the main story."

Whether we'll see the DLC worldwide on February 17th, Rockstar hasn't confirmed and we don't know how much we'll be looking to fork out for it as yet either. We'll keep you updated.
