I had to do a triple-take on this one. Internationally, the game is known as Warriors Orochi 3, but in Japan, it's called Musou Orochi 2 Ultimate. Whatever the case may be, the game has a brand new trailer showing of its Vita features, as said portable port is launching in Japan today.
In case you were wondering, this is the game that features Ryu Hayabusa, Ayane, Rachel, Momiji, Kasumi, and Sophitia. Two new stories will also be available in this version, as well as new stages and alternate events.
