Takes place after the second movie. After Knuckles joins the Wachowski family, Team Sonic is formed. But their adventures aren't over yet as Agent Stone is still out for revenge after Robotnik's disappearance.
Ever since the downfall of the Jackal Squad, Obsidian, one of the survivors, finally makes the decision to leave his boss. In desperation for a fresh new start, he turns to moving to Central City, joining G.U.N. But a 'normal life' that includes shopping malls, the internet, crowded festivals, school trips, taxes and a stubborn pigeon might not be a breeze for the young mercenary.
(Sonic the Hedgehog 2 Spoilers!) Stone wakes up in a forest a few hundred meters from the Death Egg, with a headache. (trigger warning for violence, murder and identity theft) (why the hell is there no action genre here)
Wade attempts to interrogate Agent Stone and they both get in a little over their heads.
