The next Borderlands 2 DLC is "Captain Scarlett"

It's not uncommon to find unexpected treasures hidden deep within the files of a game. The latest "victim" is of course Borderlands 2, which saw the release of its Mechromancer DLC the other day.

Hidden within the files is evidence of the game's next set of downloadable content: Captain Scarlett and Her Pirate Booty.

The new content will add the following maps:
Hayter's Folly
Washburne Refinery
The Rustyards
Manys Lighthouse
The Leviathan's Lair

New PlayStation Network trophies have also lend credibility to this reveal:

Treasure Hunter
Completed the mission “X Marks the Spot”
Discovered all named locations in Oasis and the surrounding Pirate’s Booty areas.
Completed all Pirate’s Booty side missions.

Given that Gearbox has planned a total of four add-on packs for Borderlands 2, Captain Scarlett is more than likely the first. Stay tuned.
