You can always rely on anime games to come out with Madden-style annual updates. Namco Bandai and CyberConnect 2 have announced Naruto: Ultimate Ninja Herores 2: The Phantom Fortress for PSP this June. The fighter will feature twenty characters from the popular series. According to IGN, "Phantom Fortress' story mode will have Naruto and his pals battling through a flying fortress that has descended on Hidden Leaf Village." There will also be more than just fights: there will be quizzes and mini-games.
Just like the previous iteration of the franchise, the game will take advantage of ad-hoc multiplayer (no infrastructure, we're sad to report). Game Sharing returns -- a huge plus of the original. Stay tuned for more.
