>>86570046Shadow's backstory in SA2 (as you will see from Nerissa's playthrough) is that he's a secret government experiment by Gerald Robotnik (Eggman's grandfather) to create the ultimate lifeform; Shadow befriends Gerald's granddaughter Maria but the government decide to send in a special ops team to take his research, in the ensuing chaos (heh) as Shadow tries to escape with Maria, Maria is gunned down and killed. Shadow falls into despair and is sealed away in the vault Eggman finds him in in GUN HQ in SA2. Meanwhile Gerald Robotnik is captured and imprisoned and, as he's about to be executed by firing squad, declares his hatred and vengance against the world for the death of Maria (he had actually programmed the prototype ultimate lifeform, the big creepy lizard thing, to take control of space station ARK and crash it into Earth to literally genocide humanity as revenge; this is what the final boss is in SA2 - as this is happening Shadow realizes that it isn't what Maria would want and sacrifices himself to stop the prototype Biolizard and ARK and falls into the atmosphere, seemingly dying.
After this Shadow somehow survives but has amnesia and is confused as to whether he is a clone or the real Shadow.
The Shadow the Hedgehog video game is about him uncovering who he is and deciding whether he wants to be good or evil or neutral - while Earth is being invaded by the black aliens led by Black Doom (who it turns out helped Gerald make Shadow out of his black alien DNA for some reason). Also Shadow wields guns in this game because his character wasn't edgy enough already.
I have no fucking idea what the new Shadow game is about.
