While we argue if Michael Bay’s Teenage Mutant Ninja Turtles movie is going to be any good, we do know the Xbox 360 Kinect only game based on the movie will more than likely be awful (see Star Wars Kinect) with the saving grace of the game being free.
TMNT: Training Lair is set to launch on July 22nd 2014, two weeks before the movie comes out, and will allow you to flail around slicing flying objects in a way similar to Fruit Ninja Kinect. The game is a collaboration between Paramount Pictures and Microsoft, and is not handled by Activison who currently holds the rights to produce TMNT based games.
