Ninja Gaiden Sigma 2 Plus is ready to assault PS Vita with some key new features, some of which are illustrated in the launch trailer below. In addition to the clock-beating Ninja Race, more selectable characters, and a partner-swapping Tag Mode, Sigma 2 Plus also sports a Hero Mode that makes things a little bit easier for beginners. 

Folks in North America will be able to pick Ninja Gaiden Sigma 2 Plus up today, while those in Japan will have to wait until February 28. A European release is set to follow on March 1.
