"Sir Hammerlock's Big Game Hunt" begins with a relaxing hunting trip with Sir Hammerlock, which quickly falls apart as Professor Nakayama, a mad Hyperion scientist, makes trouble for the vault hunters. It will be up to players and their guns to help the scientist get over the death of Handsome Jack.
Unlike other big titles, Gearbox's Borderlands 2 expansions aren't exclusive to the Xbox 360 for weeks before they hit other systems. The DLC will be available today for Xbox 360, PlayStation 3, and PC.
As a side note, Gearbox has acknowledged that some Xbox 360 gamers have been getting errors when downloading the latest compatibility pack update. The developer stated that it is working with Microsoft to address the issue.
