‘Grand Theft Auto IV: The Lost and Damned’ is the first expansion for Grand Theft Auto IV. It was originally published for the Xbox 360 and at later date for PlayStation 3 and PC.
The Lost and Damned features Johnny Klebitz, vice-president of Liberty City’s biker gang The Lost Motorcycle Club. This character made it’s first apearance in missions of the original Grand theft Auto IV game.
The game starts at the moment that Billy Grey, the Lost club's president, is released from court ordered rehab. Billy immediately picks up his old criminal habits and Johnny gets into conflict with him. Because of Billy’s actions the gang war between the Lost and rival gang The Angels of Death erupts again after a truce Johnny brokered during Billy’s absence. It’s up to Johnny to save what can be saved of his gang and his life.
The Lost and Damned features similar gameplay to Grand Theft Auto IV. New weapons and vehicles (especially motorcycles) are added to the game.
