It's life like the fallout games but within the Sonic Universe and some things are different like Nuka Cola from fallout is Chaos Cola in this world and instead of nukes made everything radioactive it was Chaos weapons and yes the eggman empire is still a thing so are the freedom fighters with both sonic and tails traveling together maybe you might meet them and be pals or.... If your with eggman there enemy's? Who's side are you on? And what will happen within Fallout New Mobius
