One Piece Kaizoku Musou being developed by Koei Tecmo's Omega-Force for Namco Bandai

The Japanese software publisher Namco Bandai Games registered the game trademark "Pirate Warriors" in the European Union on Thursday. The trademark was filed in English, but Spanish is also listed as the second language.

Shueisha's Weekly Shonen Jump magazine announced in September that Namco Bandai Games will be releasing One Piece Kaizoku Musou (One Piece Pirate Musou). The publisher and KOEI Tecmo Games' development studio Omega-Force are working on this "dream collaboration" that combines the pirate story of One Piece with KOEI Tecmo's Musou (retitled Warriors in English) action game franchise. As the first One Piece game for the PlayStation 3 console, the title will ship in Japan on March 1, but Bandai Namco Games has yet to announce release plans in Europe or North America.
