The gameplay still stands entirely on its own, and to this day the successful formula hasn’t really been duplicated anywhere outside the series. Hardly what you’d call a hack-and-slasher, Ryu relies on an assortment of brute force that includes normal attacks, special moves, and projectiles - used in tandem with guards and employing the environment to your complete advantage. Even while running up walls and body slamming opponents, the game’s mechanics keep to a nearly perfect balance, maintaining the experience of being a hyper agile face-cracker, without the feeling of weightless button mashing. Oh, and we even got to get our “duel wield” on, cutting up foolish foes with the brand new twin katana blades. Nice.
The PS3 version seemed a little more relenting, especially for what's known as a notoriously difficult and unforgiving game. But it's safe to assume this is to ease newcomers into the pool of pain, and increasingly brutal modes for the hardcore masochists are sure to be packed in.
In addition to the graphical overhaul, Sigma includes everything from the original game, all the way through to 2005’s Ninja Gaiden Black remix and it doesn’t stop there. More mission modes and weapons are a welcome, but a given. Perhaps the biggest and most noteworthy supplement is an entirely new, playable character. Ditching her second fiddle status, Rachel is here to pack a wallop with her own unique set of moves and 3 new chapters (bringing the total to 19) that are integrated into the storyline.
