“The Kinect features we’re exploring with ‘Halo: Anniversary’ are additive and will not affect the core gameplay experience or alter our mission of delivering a faithful recreation of the original game. That said we have nothing else to share just yet.”
Halo: Combat Evolved Anniversary releases on Xbox 360 November 15th.
