Last week Killer Instinct added Shadows Mode, which analyses a player's fighting style and creates an A.I. clone that does everything they do -- including celebrating a win with a good teabagging.
In TGF1Gaming's video below (via Polygon), we see a fierce battle between a Jago player in white and his game-crafted shadow in blue and red. Killer Instinct'd Shadow Engine analysed how this IceWater714 plays and created a ghost warrior based on his actions, some of which were a little unsportsmanlike.
The Shadows Mode, detailed over at Xbox Wire, is a pretty nifty way to analyse your game, and also allows your friends to beat you up when you are busy elsewhere. Considering how poor my KI game is, I am terrified to use it.
