1:There are alot of different ways. 2:What part are you talking about?
Beat the Final Boss, Dark Gaia after finishing Eggmanland
Chip learns his name which is Light Gaia. He helps sonic beat dark Gaia, they win(of course) and chip and sonic go separate ways
at the end of the game at the last boss lv you turn super and try to beat dark gaia
It is highly doubtful that it is possible, without the use of a cheat device of some kind.
You have to get as many rings as you can and hit all his eyes out and if he trys to attak you with all his hands get in the middle because there is a square there.
Well Sonic Unleashed had a better storyline and more fun gameplay. You collect chaos emeralds and get to beat the snot out of robots and Dark Gaia's friends. Sonic 4 is completely different and is sort of a cliffhanger story. Even though the cliffhanger will be gone when Episode II comes out, I would recommend Sonic Unleashed more than Sonic the Hedgehog 4.
he is easy. first off you are gaia collessus (or how you spell it.) you must swing the wii remote or nunchuck (or both) at the right time to hit him. repeat this process until dark gaia grabs gaia collessus. you must now hit his eyes. you have to run and quickly hit them. repeat this process 3 times and then you turn into super sonic. get as many rings as you can. then when it shows the wii remote swinging swing it. repeat this process and you beat him. hope this helps.
You beat the last boss
After you beat the Dark Gaia Phonix if you don't have enough Sun medals earn some if you do you switch to day and do the day time stage i think cause i passed that part already and i believe after you beat it then you will get to do daytime daytime stage for Spagonia good luck Malinkalol,
To be super fast,You need to have 100,200'or more coins to be super fast on Sonic Unleashed
Quite hard ---------------------------------- its defiantly not a game you can beat in a day lol
To get dark sonic you must beat the game with every character in the game S.F.G.X.That unlocks mission mode. Beat mission mode and dark sonic is yours if you have trouble go to the youtube user marjosonic and start at video 9 or 8 [I forgot]
