Borderlands 2 DLC will be "Sir Hammerlock's Big Game Hunt," according to PS3 game files Gearbox forum members spotted in today's patch. Gearbox has confirmed this information to us.
Sir Hammerlock's Big Game Hunt, aside from having massive beasts and crazy guns (we assume), has three new trophies/achievements: one for completing "The Fall of Nakayama" mission, one for completing all side missions and the last for discovering all named locations in the Hunt.
The Borderlands 2 Season Pass includes access to two more DLC packs, including Sir Hammerlock's. The previous pack, Mr. Torgue's Campaign of Carnage, dropped on November 20, and we found some of its missions to be "downright weak."
