In some of the best marketing I've seen in my entire life (and yours too), the makers of Ninja Gaiden Sigma 2 went and attached some fake plaster boobs to a wall. I just pre-ordered like 80 copies and I don't even own a television or video game console.
The plaster mammaries assumedly belong to Sigma 2's Ayane or Momiji -- both are playable in this iteration of the game (the text which appears at the end of the video actually says "a female ninja appears")
The video consists of a bunch of people walking by and touching the breasts, which, be honest, you would have too. There's no shame in my game -- I totally would have. Then I'd have come back that night with a chisel AND MAKE THEM MINE.
Thanks to Richard, who could sell safety matches to the devil.
