20 years without you

It's been 20 years since Sonic, supposedly, died. 20 years since the start of Eggman's conquering of the world, which he had successfully done so.

Shadow, whose still grieving, continues to try and fulfill the promise he made to his deceased lover, bunkered up in a secret base the young fox, Tails had created to house the resistance.
It is up to Shadow, Tails, Knuckles and the rest of the gang to intrude Eggman's base and begin the end of his reign. Still, before they can do so, they will face many questions, suprises and mysteries on their way to that goal.
