Famitsu has details about what’s new in Ninja Gaiden Sigma 2 Plus. The PlayStation Vita version has Ninja Race mode where Ryu grabs items that give him a speed burst. Tag Mission is another new mode that lets players switch between Ryu, Ayane, Rachel, and Momiji.
Team Ninja added the three kunoichi for Sigma 2 and created new missions for them. Ninja Gaiden Sigma 2 Plus will retain all of the content from the PlayStation 3 game. Tecmo Koei plan to release the title on February 28, 2013 in Japan.
