Namco Bandai hasn’t announced Naruto: Ultimate Ninja Heroes yet, but EB Games has a page explaining what is supposedly in the PSP game.

20 characters? The Japanese release had 23 after unlocking all of them. Maybe the EB Games page is keeping the other 3 characters as a “secret”. There’s also lots of emphasis on the “team” system where you explore the mysterious tower with a squad leader and three other characters. Skills let you pass through the dungeon faster by breaking walls and spotting hidden passages. The minor details about Naruto: Ultimate Ninja Heroes makes the game sound like Naruto: Narultimate Hero Portable. However no details were given about the story or the “make your own labyrinth” system which some gamers loved and others loathed.
