Jump Magazine revealed One Piece: Super Grand Battle X in this weeks issue. The game is a 4 person alliance battle game, we're not sure what that means (similar to Powerstone or SSB maybe?), which will see you creating a small team to combat foes. 85 characters are reputed to be in the game and each will feature a Chibi styling. This latest One Piece release is due in Japan at the end of the year for the Nintendo 3DS.
