Talking to USA Today, Rockstar's Dan Houser said the extra content would be hitting the Xbox 360 on 17 February. Dubbed "Lost and Damned", it'll focus on a member of The Lost biker gang, which Niko brutally slaps down after a lengthy bike chase near the start of the game.
The new character, Johnny Klebitz, has been described by Houser as, "A very different character than Niko, with a very different background." Whether that means he lacks a taste for mafia–based violence and casually offing members of the public remains to be seen.
It's set to cost about £15 when it launches. Pricey, but if means reigniting our passion for barging around a fictional city and acting like the big I am, we're happy to stump up the cash.
