If you've wanted to immerse your body in a first-person shooter, you've typically had to use a complex simulator. Battlefield 4 may soon provide a decidedly simpler (and cheaper) alternative. DICE's Patrick Bach has revealed to Xbox Wire that the game may use the Xbox One's Kinect sensor for head-tracking look controls, such as leaning around a corner. Voice commands might also be available, Bach says. There's no guarantees that BF4 will get the new input methods, but DICE may have competition as an incentive. Infinity Ward recently hinted to Official Xbox Magazine that Call of Duty: Ghosts could use Kinect for more than navigating menus, so there's a chance that at least one of the two games will have motion control in the future.
