With the March 1st release approaching quickly, we’re starting to learn more about Kaizoku Musou or One Piece Musou. The first is the inclusion of a few more arcs. It would seem they’re pulling out all the stops with Buggy and Arlong’s arcs confirmed, but the Baratie arc and Drum Island (implied) too. This also means Chopper/Sanji will be playable as well as Don Krieg.
Additionally it appears that there will be a support system. No word on how expansive it will be, but this could be great if you’re a fan of a niche character.
