One Piece: Gigant Battle

One Piece: Gigant Battle! (ワンピース ギガントバトル！ Wanpīsu: Giganto Batoru?), previously known as "Project Jet" (プロジエクトシエット Purojekuto Jetto?), is a Nintendo DS game published by Bandai. It was first announced in the second Weekly Shonen Jump issue released in December 2009. It will focus in the Sabaody Archipelago arc, Impel Down arc and Marineford arc, but contain content from previous arcs as well. The gameplay seems to be similar to Jump Ultimate Stars from what has been demonstrated in videos and screenshots. The game was released on September 9th, 2010. There will also be a special edition of this game (seen in the promo scan to the very right) which will come with some cards that unlock in-game content and can also be used in a One Piece arcade game, One Py Berry Match, which is part of Bandai's "Carddas" series of games.
It seems that this game was very popular among One Piece fans and leading to the reason why Ganbarion and Namco Bandai announced the release of One Piece Gigant Battle in Europe on June 2011, however, the exact date is unknown at the moment.
