Ryo Harabusa returns to PS3 in this exclusive sequel to Ninja Gaiden Sigma.
Ryo's joined by two new playable characters this time around, both with their own stories and levels interwoven into Sigma 2's overarching plot. Ayane, the buxom purple-haired beauty of Dead or Alive fame is be playable, as well as Momiji, the young female ninja first introduced in DS title Ninja Gaiden: Dragon Sword.
A new online co-operative mode allows gamers to slash down enemies together in various arena-based challenges, but the violence has been toned down a little from previous titles, with Team Ninja claiming that their focus is on the 'cooler aspects' of Ninja Gaiden.
