"The Lost and Damned (TLAD) is Rockstar & Microsoft's exclusive add-on that allows you to play a whole new chapter in the GTA:IV Liberty City universe. You take on the role of Johnny Klebitz, biker and stand in leader for the bike gang "The Lost and Damned" due to the regular leader, Billy Grey, being thrown into jail. (Ed- So it's much like real-life Melbourne then…).
Things seem peaceful as Johnny 'K' has managed to maintain peace with bitter gang rivals "The Angels of Death"; that is until the former head and founder of the club Billy Grey returns from his stint in prison. Immediately he resumes his former post and sets about returning things to the way they were, and essentially all of Johnny's hard work is thrown out the window."
