One of the most iconic "power-ups" in gaming has to be Metal Gear Solid's cardboard box. This new Japanese ad for Kojima's latest, Peace Walker, gives the stealthy item the spotlight. In the commercial, a Japanese schoolboy can be seen stalking a few of his fellow classmates. As he finds the two alone, he strikes, asking them to "please enter my box."

Unfortunately for the girl, the box boy wasn't asking about her. He invites the other boy into the cardboard box, as the commercial introduces the new co-op box-wearing mechanic of Peace Walker. You can check it out after the break.
