A poster on popular gaming forum NeoGAF has discovered a listing on Amazon.fr for Ninja Gaiden Sigma 3 on both Xbox 360 and Playstation 3. It has a release date of March 5th 2013. The previous two Ninja Gaiden games have each had Sigma follow ups which added extra content, including new playable characters and even multiplayer.
Ninja Gaiden 3 recently recieved a similar treatment when it was released on Wii U as Ninja Gaiden 3: Razor’s Edge. That port included Dead or Alive’s Ayane as a playable character as well as reinstated the dismemberment aspect of combat from Ninja Gaiden 2 which was removed in the transition to Ninja Gaiden 3. One could speculate that a Ninja Gaiden Sigma 3 release would be very similar if not identical to the Razor’s Edge version, minus Wii U specific features of course.
All speculation at this point, but we’ll be sure to keep you updated if or when this release is confirmed.
