The Ninja Gaiden series has had a habit of each release reincarnating in other various forms. The original (3D) game first hit the Xbox, and then Ninja Gaiden Black followed that up on the same system. Ninja Gaiden Sigma then hit the PlayStation 3 a couple years later, bringing with it many of the enhancements of Black along with new sections, a slightly expanded story and, of course, updated HD visuals. When Ninja Gaiden 2 was announced for the Xbox 360 at last year's GDC, most Sony fans knew that it was only a matter of time before it gained the Sigma bit of its moniker and made its way to the PS3. That time is almost here.
IGN recently received an updated demo build of the game there in the office that offers up small sections of play for not only Ryu, but Ayane and Momiji as well. These two female warriors are of course new for play in Sigma 2, and they will be joined by Rachel in the final game, who was also playable in the original Sigma.
