While Namco didn't do a stand alone Pac-Man title for Kinect, the Tokyo-based game company does have a special cameo for pellet muncher in its new brain training game, Brain & Body Connection.
In this mini-game, this goal is to avoid the ghosts with one hand and touch the fruit with the other. More points are earned the longer players are able to keep their hand on the fruit. It's a bit like rubbing your stomach and patting your head at the same time, but with added arcade noises.
