Set five years after the events of Borderlands, Handsome Jack, the game's main antagonist, has taken over the Hyperion corporation, has declared himself Dictator of Pandora, and stolen all of the credit for finding the Vault, going so far to claim responsibility for killing the Destroyer. Jack has also blotted out much of the light on the planet by having a giant orbiting H-shaped base set in front of Pandora's stationary moon. The new team in Borderlands 2 is tasked with killing Jack and returning peace to Pandora.
Borderlands 2 is a GREAT game, the re-playability value is endless and the game is long enough as it is. Everything about it is pretty solid other than a few small bugs here and there when playing Co-Op mode. Overall its a 9.5/10 in my book, easily the 2012 GOTY.
