The next chapter in the story of dark Japanese hero Ryu Hayabusa will take a look at the man beneath the mask; a man that struggles internally over every life he takes. I'm guessing that's after he showers off the gore.
Once you wipe away the blood you'll see these screenshots are depicting Ryu's trip to modern-day Dubai, where he'll struggle against the machinations of the Alchemist Forces and his own inner demons, stabbing both with equal parts ferocity and remorse. He'll also run into Mizuki McCloud, an attractive young woman that, judging by the fact that she's not bathing in offal, Ryu seems to be friends with. Or maybe Tecmo Koei is just saving the bloodbath for later.
We'll know for sure early next year, when Ninja Gaiden 3 hits the PlayStation 3 and Xbox 360.
