GamerXChange: "The legendary Ninja, Ryu Hayabusa, is back with all of his high flying action, sword slashing, and this time in the palms of your hands in Team Ninja’s re-imagined Ninja Gaiden Sigma for the new PlayStation handheld, the Vita. The game is a port of Ninja Gaiden Sigma for the PlayStation 3 ... with some new features including making use of the Vita’s touch and motion functions.
The game brings back all of the action you love and the impossibly challenging gameplay. However, this version comes six years after the game’s (Ninja Gaiden Sigma) release, so how does it hold up on the portable?" 7/10
