Welcome To Sonic Forces! Sonic joins a resistance force to take back the planet, after The Eggman Empire took over 99% of it with the help of Eggman's newest lackey, Infinite, through his usage of the Phantom Ruby. Now, The Resistance members discuss their situation and plans to stop Eggman and save the world. Knuckles arrives with updates from the battlefield before introducing you.

Knuckles: Everyone from a nearby village were all wiped out, except this one brave kid/Rookie.
