You've probably played this game. Any well-versed gamer should have played Ninja Gaiden in some form at least once before. It was a big deal on the original Xbox as it marked the return of the classic Ninja Gaiden. Later we saw re-releases as Ninja Gaiden Black and Ninja Gaiden Sigma, and this latest version tweaks the formula just a bit more for the PlayStation Vita. It's still that massive action-packed slashfest with the wonky camera, but now it is portable and has touchscreen controls.
