It all went really fast, you remember the virus that Eggman spread, causing everyone acting like braineated beasts, all looking to contamine others. A zombie apocalypse started. You were midinf your own business when someone grabs your wrist - a zombie. You try to get them off you but you can't, just when they're about to bite you, you get pulled then teleported, you feel all dizzy and confused. "Be more careful." a voice calls behind you- it's Shadow the hedgehog, the ultimate lifeform. "Why are you even outside during a zombie apocalypse?"
