Harmonix is currently recruiting for a mysterious new IP, which will be a unique motion gaming IP. You can see that there are several jobs listed here but certain ones are affiliated with the new project. The Narrative Designer sports the following description “incorporate creative story lines into gameplay on a unique motion-gaming IP”. No platforms are mentioned but considering the heritage Harmonix has, Kinect is most probably on the cards. Whatever it is, we’re definitely going to be interested in what this becomes.
