Set over 6 Zones of 3 Acts, Shadows Fall will tell a story, in the same vein as Sonic Rush and Chronicles, and power up Shadow with various upgrades along the way. Shadow is the only playable character planned right now, but he will be able to interact with several new characters, as well as a couple familiar ones...

100 years after the destruction of the Eggman Empire.

The immortal Shadow, no longer plagued by guilt and bad memories, is living a peaceful life, and has even managed to make a few friends. On the anniversary of Eggman's defeat, his factories spring back to life, the airfleet once again blocks out the skies, and the machine army finds a new leader.
