Mifune along with Hanzo and Hokage Naruto will be playable in Naruto
Shippuden: Ultimate Ninja Storm 3! At least that’s according to Japanese
blog
TaleTaleSource, which often correctly reveals information that will be in the up-coming issue of Shonen Jump.
Mifune is the General from the Land of Iron while Hanzo is the former
Hidden Rain Village leader. Since the up-coming episodes of Naruto
Shippuden will feature Hanzo in the reincarnated form through Edo
Tensei, that is the version we can expect to be playable. And if you
remember Hokage Naruto from Naruto Storm 2, well, he is making a
comeback! He will be playable from the start if you have a Naruto
Generations save file on your PS3/360.
