Go to Knight's Passage after you beat King Arthur for the second time and do the Beat the Clock mission.
Sonic and the Black Knight
What I'm made of from the last stage of Sonic Heroes
whichever one you unlock last. that doesn't mean go figure it out... there's just no significant last mission.
Once you finish Sonic, Shadow and Silver Story, Last Story appears on the story screen.
Once you finish Sonic, Silver and Shadow's story, the last story becomes playable.
Yes. In Sonic Adventure 2 (Battle), only in Dark Mode and Last Story. Also in Sonic Battle, Sonic Heroes, Shadow the Hedgehog, Sonic the Hedgehog (2006), Sonic Riders, Sonic Riders: Zero Gravity, Sonic Free Rider, Sonic and the Secret Rings, Sonic and the Black Knight, Sonic Chronicles: The Dark Brotherhood, Sonic Rivals, Sonic Rivals 2, Sega Superstars, Sega Superstars Tennis, Sonic & Sega All-Stars Racing, Sonic & All-Stars Racing Transformed.
To unlock the Last story on Sonic Heroes, you have to play all other stories:team sonic, dark, rose and chaotix all the way through (100%)
you can only use it on the last story
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.
just the last story is when u can be super sonic. (U UNLOCK LAST STORY ONCE U BEAT ALL STORYS WITH ALL CHARECTERS)-spoiler-u battle chaos in his most powerfull form.
If you mean the old one (1991) then you can't. But in 06, you just have to get Last Story.
