[Update] To put minds at ease, Microsoft has issued a clarification:
Just to let everybody know, the Kinect features we're exploring with Halo: Anniversary are optional and won't affect your core gameplay experience. Our mission, from day one, has been to deliver a faithful recreation of the original game, and we remain dedicated to seeing that through to completion.
[Original Story] Microsoft is making a push to include Kinect support in core games this year, and that apparently includes their remastered version of an old favorite. Halo: Combat Evolved Anniversary will use Kinect according to Microsoft Game Studios general manager Phil Spencer.
"As a first party, we believe that Kinect will be important to all genres of games, be it racing games with Forza, combat games like Ryse -- even games like Halo Anniversary has Kinect integration," Spencer said in an interview with GameSpot.
Spencer didn't mention exactly how Halo Anniversary will work with Kinect. The game doesn't have a squad to command like Mass Effect 3, so it's anyone's guess how the device will be used. That means until Microsoft officially dispels it, you can at least hope for a Cortana make-out mini-game. Weirdos.
