Not even resting for Sunday, this page on the Gathering of Developers website now offers the fourth in the series of gameplay movies taken from Oni, Bungie's imminent game of personal combat. The clips, which are being released on a daily basis until the game becomes available on January 29th, are intended to teach maneuvers to willing pupils that will offer tactical advantages in the game from the day they bring the game home. Today's move is called the "Devil Spin Kick," though if you tell your friends what the move is called after you spring it on them, they'll probably catch on you were studying in advance.
