After some earlier rumors of it’s announcement, Namco Bandai has announced Naruto Shippuden: Ultimate Ninja Storm 3 in this weeks Shonen Jump. Sadly not much is currently known, but it seems that the boss battles are back. This shouldn’t come as a surprise, as it was the biggest complaint of the last game. Additionally Naruto is shown in Nine-Tails Chakra Mode, so it should cover the 4th Great Ninja War or at least some of it.
Finally the game is set to release in 2013, but a firm date is not currently known. Ideally this will lead to the war being fully covered, but time only time will tell. Check back to JustPushStart for more information as it arises.
