Bandai Namco is developing a 2D action game titled One Piece Dai Kaizoku Colosseum for the Nintendo 3DS.
Weekly Shonen Jump will release more information later. The game doesn't have a release date yet. What is known is that the game will feature a mode where players can create their own pirate crew and explore the world.
In battle, special moves are activated by pressing buttons with the right rhythm. As the player defeats opponents, the bounty on their wanted poster increases.
