The trailer for Xbox 360 title Ninja Gaiden II was a pure gore porn, complete with bloody slicing and dicing. The trailer of the PS3 reworking Ninja Gaiden Sigma 2 seems, well, different.

For starters, the action scenes don't look like a butcher shop. In place of decapitation, the trailer shows innocuous red slashes and vaporiffic blood. Since when is "Sigma" Greek for "toned down"?
