Once you finish Sonic, Shadow and Silver Story, Last Story appears on the story screen.
There are 4 episodes Sonic, Shadow, Silver and Last, you unlock Shadow by encountering Shadow in story mode, and Silver's story is unlocked by encountering Silver in Sonic's story, last story is unlocked by beating all 3 hedgehog's stories, none of these are 'hidden' per say, but there the only episodes or stories in the game.
Once you finish Sonic, Silver and Shadow's story, the last story becomes playable.
Sonic Next Gen, but is given life by the chaos emeralds.
you have to get all the chaos emeralds in the game
If you mean the old one (1991) then you can't. But in 06, you just have to get Last Story.
keep doing the last boss battle trust me i have the game and i do it all the time
Sadly, like every game since Sonic Adventure, you can play as Super Sonic ONLY in the Last Story.
Complete the main story line of Sonic's story, Shadow's story AND Silver's story. You don't need to do any town missions if you don't want to.
If you mean the last boss in his story, you have to catch the big fireball he sends and launch it back at him in order to win
I came up with 2 possibilities:1. In one episode of "The Adventures of Sonic the Hedgehog," Sonic says: "That's Hedgehog. Sonic the Hedgehog." Although this is just supposed to be making fun of the James bond series, it could actually be...2. In "The Adventures of Sonic the Hedgehog," Sonic calls Tails his "little bro." Since all brothers have the same last name, and Tails' last name is "Prower," that could also be Sonic's last name.Okay, Sonic's last name is actually Hedgehog.
For The Last Boss.
