The Lost and the Damned is the first episodic downloadable content for Grand Theft Auto 4. What exactly is episodic content? Well, it's an entirely new story. Not only that but it's got new weapons, vehicles, characters, and multiplayer modes. For $20, you're getting an entirely new adventure in the GTA4 universe...but you're also getting a smaller one than you got in the original title. The story for TLAD is about 8-12 hours long (to complete the main missions). There are a lot of extras, though, such as races and gang wars which can take you as long as 20+ hours to complete. This is definitely the most robust DLC available on the Xbox 360 to date.
