The path of the ninja is a difficult and deadly one. It’s brutal and bloody, and if you have the skills to walk it, it’s immensely satisfying. 2007’s Ninja Gaiden Sigma for the PlayStation 3 was a great update of one of the greatest action games of all time. Now, it’s on the Vita as Ninja Gaiden Sigma Plus, and although the implementation of Vita features occasionally gets in the way, the years since Sigma’s original release have done little to dull its edge. If you’re up for a challenge and you haven’t walked this path before, don’t let this opportunity pass you by.
