Ninja Gaiden 3 looks an awful lot like the two core games that came before it. The environments and enemies are different, to be sure, but our hero Ryu Hayabusa moves in the same basic ways. He still runs with purpose and unfathomable agility, and the swings of his sword look frighteningly lethal. The graphic level of gore featured in the Xbox 360 version of Ninja Gaiden 2 is still missing in action, but Ninja Gaiden 3 still features a ton of evisceration. The actions that lead to all the instances of said evisceration may be too simple to be inherently satisfying, but the game seems to go out of its way to increase the sense of impact created by steel cleaving through flesh and bone. The main drawback with the visuals has to do with the inexplicable slowdown you'll experience from time to time.
Ninja Gaiden 3 sounds just fine. All the on-screen action sounds as chaotic as it looks -- and it often looks extremely so. Enemies scream in agony as they are pierced, flayed, and impaled; the sounds of the piercing, flaying, and impaling are squishy and gruesome. The soundtrack is more or less what we've come to expect from the Ninja Gaiden franchise. Nothing to jump up and down about, but certainly befitting the actions of a badass master ninja.
