2K Games and Gearbox Software announce the release of Sir Hammerlock's Big Game Hunt, the new DLC for the Windows and console editions of Borderlands 2, the role-playing shooter sequel. This is included for season pass holders, or available as a separate purchase for other owners of the game. Here's word on what this adds:

Sir Hammerlock’s Big Game Hunt takes place in Aegrus, the uncharted territory deep in the swamps of Pandora and features new appearances by familiar friends like Sir Hammerlock and Claptrap. It also introduces some all-new characters, like Hyperion Scientist Professor Nakayama, who wants nothing more than to derail your hunting trip. With Borderlands 2’s cheeky adventurer as their guide, vault hunters will explore the all-new environments of The Sun Swamps while on memorable quests to collect irresistible new loot and fight devastating new bosses, such as the cave-dwelling beast Thermitage. All the while, up to four friends will cooperatively hunt down new enemies such as the spider-like Two-Legged Drifters, flying Slagged Spores and insane Vampire Witch Doctors – that unleash swarms of blood-thirsty bats. Vault hunters beware: this is sure to be the most dangerous Borderlands hunt yet!
