Record Run appears to be a new mobile game from Rock Band, Dance Central and Fantasia: Music Evolved developer Harmonix.
Internet sleuth Superannuation turned up a couple of references to the unannounced title.
The first is a WhoIs record for the RecordRun.com domain name, which is registered to harmonix (or quite well-faked).
The domain currently redirects to a Facebook page, which is the second bit of intel.
“Record Run is an exciting new game coming soon to mobile devices. Come back soon for more info, updates and offers,” the page reads.
We can probably expect more information at PAX East from April 11 through 13; Boston is Harmonix’s stomping ground, and it has traditionally shown a strong presence at the show.
