Namco Bandai and Tecmo Koei will release their One Piece collaboration One Piece: Kaizoku Musou on March 1, 2012 in Japan, the latest issue of Jump has revealed.
The game sees the One Piece anime infused with Dynasty Warriors-esque gameplay, thus the Musou in the title. Developer Omega Force has said the game is sticking as true to the anime/manga as possible.
Thanks, Hachimaki.
