Everything wrong with the one feature that sans its inclusion has unshackled the Xbox One from meme-based ridicule, and reinstalled it in the living rooms around the world; Fighter Within remains something that looks just as unpolished in-motion as you do feeling daft controlling it. It was a pretty cool idea on paper and an early attempt at convincing everyone of the Kinect's motion-sensing prowess, but the end product was just a downright terrible experience. Failing to recognise even the most telegraphed punches and giving you a multiplayer mode that was more likely to amount to you removing a few of your friend's teeth by accident, Within has since been banished to the failed concepts pile along with the Kinect itself.
