Jump is out with more details about One Piece: Pirate Warriors 2. Namco Bandai and Omega Force included the Thriller Bark arc to add a touch of horror to the standard Warriors game.
Gekko Moriah is the boss in the Thriller Bark stage. Perona shows up in Thriller Bark too as a playable character and she can use her powers to make ghosts appear.
One Piece: Pirate Warriors 2 comes out in North America and Europe this summer.
