Um, evidently via the SIXAXIS controller, one can manipulate breasts in the forthcoming Ninja Gaiden Sigma 2. I kid thee not:

While the commercial itself is amusing, the fact that this is a gameplay feature being highlighted is not. What is the purpose? To appease perverts? Or is there actually going to be a level designed around making one boob bounce higher than the other in a sneak attack to knock out a guard and steal his key to the castle? Somehow, I doubt it.
