I was doing a little search for more info on on sonic unleashed and found something i thought was interesting
There are nine levels based on real places in the world.
Im not to sure about this one but this is what i herd....
At night you turn into sonic dark side into a werewolf, but he goes extremely slow, but is aloud to pick up items like s stop sign and attack enemys with it, sorta similar to shadow the hedgehog,
NOTE: This does not work for sonic the hedgehog
There are two came mode types, theres 2D MODE which is on every level at some part, which brings back memory from the old sega, and then theres 3D mode which is in most of the game.
The working title was Sonic world adventure. Which you will here that later when you play the game.
These are the characters that confirm will appear in sonic unleashed (Sonic world adventures)
# Sonic the Hedgehog
* Super Sonic
* Sonic the Werehog
# Miles "Tails" Prower
# Doctor Eggman
# Amy Rose
# Knuckles the Echidna
# Shadow the Hedgehog
# Dark Gaia
Thats all i really know so far...Ill post more when i get a chance and find more!
