Having accidentally stumbled out on Xbox's official site earlier today Fable Heroes has now been officially unveiled, with the four player beat 'em-up confirmed to be coming to Xbox Live Arcade later this year.
Fable Heroes is being developed in-house at Lionhead by a team headed up by Fable 3 quest designer Ted Timmins. It's the work of 20 employees, and development commenced last April - and while a release date hasn't yet been confirmed, it'll be prior to the release of Fable: The Journey this September.
Fable Heroes feeds into the Kinect-exclusive Fable: The Journey, with avatars and unlockables being shared between the two. Unlike previous Fable tie-ins such as Kingmaker and Coin Gold, Fable Heroes is a fully-fledged game, featuring drop-in/drop-out co-op and a slew of content.
There's no price-point just yet, although Timmins hinted that it will come in at the lower end of the XBLA scale.
