Along with the new trailer for the first episode of Grand Theft Auto DLC, The Lost and Damned, Rockstar has released a batch of screens showing off the subtle nuances of biker gang culture.

The 8 new screens pretty much cover all the bases you'd expect shots from a motorcycle gang-based GTA IV expansion to cover. You have tough guys on bikes, tough guys shooting at things, tough guys being tough, and the odd explosion thrown in to give the whole thing a little zest. If there's one thing I know about bikers, is they like adding a little zest to things.
