I've told you, Totilo's told you and McWhertor's told you: you can't get through Red Steel 2's swordfighting combat by just flicking your wrist once or twice.
But if you're sick of us telling you that — or you'd just prefer to hear it in the developer's own words — check out Ubisoft's new Red Steel 2 Insider video. You not only get the background technical explanation of why MotionPlus is a must, but some actual footage of sword-swinging gameplay.
Red Steel 2 is out sometime next year.
