In some ways, Ninja Gaiden III: Razor’s Edge is like a completely new game. While the Wii U version uses the PS3 and Xbox 360 release as its base, Team Ninja is making a number of additions and changes.
According to the latest
Game Informer, Team Ninja will also be including Ayane as a playable
character. She’ll have her own “narrative-expanding missions”, complete
with a new move set. The Wii U version also allows players to accumulate currency by pulling off combos, and can then use the cash to purchase moves, sword upgrades, and magic spells.
