Naruto Shippuden Ultimate Ninja Impact for PSP promises massive 1 vs 100 battles and boss battles with Eight Tails and The Six Paths of Pain. Yikes!
Ultimate Ninja Impact, from Cyber Connect 2 and Namco Bandai, is due at some point this year and features a story that takes players from the beginning of the Naruto Shippuden story all the way through to the current story arc. With a simple control system, players of all skill levels will be able to get in on the action, either 1 on 1 or 1 on 100. Massive boss battles and two player co-op action will also be available.
