Borderlands 2's first major expansion looks like it's called Captain Scarlett and Her Pirate's Booty.
The add-on's existence was outed by new PlayStation 3 Trophies relating to the DLC, added in the game's latest title update (which went live on PS3 yesterday alongside the new Mechromancer character).
Captain Scarlett will offer a spectrum of new features, including the new location of Oasis, new missions, weapons, bosses, raids and a fresh rarity level.
Dialogue is set to include the lines: "You slagged-up fistomitch! DIEEEE!" and "I am the Censorbot. All lewd behavior must be stopped. A deviant known as P3RV-E is in possession of sexually explicit materials. Please murder him, because morality."
Captain Scarlett and Her Pirate's Booty has yet to be announced by Borderlands 2 developer Gearbox. It's presumably one of the four major add-ons included in the game's Season Pass.
