YouTube user Sackula has gotten his hands on Ninja Gaiden: Razor's Edge for Wii U and uploaded a ton of footage for those curious. Among the sessions below you'll see Momiji and Kasumi in action, the latter of which is apparently difficult to use, at least in comparison to the other characters. As such, Ninja Gaiden veterans may enjoy mastering her.
Two of Sackula's videos are below. For more, head to his channel via the source link.
Razor's Edge is the enhanced version of the original game. It's available now.
