Ninja Gaiden Sigma is an action game like no other. There are similarities with the awesome God of War II, but if you consider that epic as an arcade experience, then Sigma falls somewhere in-between arcade and sim. Getting your head around the combat is key to having a good time. Once mastered, you'll find an immersive action romp full of original challenges, incredible environments and interesting characters. This game might have been around for years, but the intensity of the gameplay has yet to be bettered.
