You can still play the whole game without Kinect though.
D4: Dark Dreams Don’t Die is a rather unorthodox action adventure title – which is to be expected when Deadly Premonition creator Hidetaka “Swery” Suehiro is behind it – and looks to implement Kinect in new and interesting ways. In a new interview with OXM, Suehiro has revealed some interesting new details on the game, including trying to implement facial capture into the gameplay.
Firstly, you don’t need Kinect to play the game. D4 can be played using the controller. For Kinect players, you’ll have certain action sequences wherein you need to take a stance similar to the one on-screen. This is your Synchro Action and performing one correctly will fill up the Action bar. The bar can also be filled if you choose wisely in your dialogue and act all detective-like.
“The original Kinect was enough for me to come up with the concept for D4, but for using the player’s whole body in various poses, the new Kinect is indispensable.
“For one thing, it can now track all your fingers, and for another it lets you play sitting down. Voice control makes the interaction more responsive, and you can get closer to the screen and even play in a dark room. The new Kinect can even read your facial expression, so I’m currently finding a way to implement the player’s empathy.”
D4 is currently exclusive to the Xbox One.
