Ninja Gaiden Sigma 2 is set to hit stores on October 1 in Japan. Once an Xbox 360 exclusive, Ninja Gaiden's PS3 return combines the 2008 Xbox 360 sequel with new features, including online co-op, two new playable characters and planned fixes to a laundry list of issues found in the original game. Ninja Gaiden Sigma 2 is priced at ¥7,800 ($80 US). According to Kotaku, pre-order bonuses for the game include a "starter guide book" and download code for the original Ryu Hayabusa character costume. Better get a good stain remover, getting blood out of a Gi is hellacious.
