Ninja Gaiden Sigma 2 is the remade of the Xbox 360 Version , It has got some new additions But fewer gore and violence.
the story is the same as the 360 version ..you fight as Ryu Hayabusa , a ninja trying to avenge his clan , a mysterious artifact is stolen by the black spider ninja clan that will wipe out the world ,so Ryu have to hash and smash his way to save the world.
you wold find some new bosses ,few new enemies and a new weapon for Ryu, it is powerful but slow so you would consider using another weapon for fast enemies.
the graphics are great and looks as good as the 360 version but sometimes the 360 has the advantage even after months of polishing.
what differs from the 360 version is that the enemies wont hide beside walls or corners but will jump in front of you as you come to a new area , more save points were added and you would spent less money on weapons and upgrades so this makes it easier , sometimes you wold miss enemies in some areas and you would not find them as many as the 360 version.
Unfortunately the loading is lengthy even after you install the game on the system.
the new characters are not all that fun .. Ayane is fast but have less power than Ryu .. the other female is stronger but slower looking as Rachel in the first sigma ..
well this game is a disappointment ,it doesn't have what many did expect but if you didn't play it on the 360 play it on PS3
