An expansion/retelling of the original story presented by Sonic Forces, adding on to the lore surrounding the events of the war. The heroes have been overwhelmed by an army of old foes, Sonic is presumed dead, and Eggman has claimed the world for himself. It's up to those few heroes who remain to take it back. They won't be working alone, of course- new faces have risen up to help!

When dark forces enact their influence on the Magic Kingdom's inhabitants and destroy the Sorcerer's Hat, it is up to Mickey, Donald, and Goofy to venture through the different 'attractions'. To restore their only means of defeating their enemies, they'll have to help memorable characters and battle iconic foes. A battle between light and darkness has begun.
