Ninja Gaiden Sigma 2 slices and dices North America this September

You read that right, folks. The co-op compatible, new and improved Ninja Gaiden Sigma 2 will (Izuna) drop into stores on September 29th. Arriving just in time for the busy holiday rush, this updated version of the 2008 Xbox 360 exclusive features two three extra playable characters, along with a puzzling reduction in violent displays.
