Additionally, the PlayStation.blog took some time (10 minutes, actually) to show off the various features of Sigma. You'll get to see the Ultimate Ninpo in action, as well as an extended look at the new co-op mode -- and yes, you'll even see the franchise's notorious Game Over screen. Check that out after the break.
