How do you kill dark gaia in sonic unleashed?

Answer 1

1. For PS3 Boost To Dark Gaia With Chip 3 Times But Sonic 3 Times Too. Alright First Boost To Dark Gaia With Chip
2. Then Do Sonic You Have To Do It 3 Times
3. Super Sonic Time alright collect rings To Fill Sonic`s Heath Then Take Out All Snake Things If Chip Dies You Lose Then Press A Few Buttons Then Press square 50 Times Then just Wait If You Hit His Hand You Wont Die On The Last Part

If you want a better answer then read. When you destroy Egg Dragoon you become Gaia Colossus. You boost, then you destroy, Dodge, or go under the rocks. When you hit all three eyes of Dark Gaia with Sonic, Dark Gaia becomes Perfect Dark Gaia. When you are Super Sonic you must get as many rings as possible then, when you reach the shield take out the snake things before you or Chip (Gaia Colossus) get destroyed. After the shield is gone Perfect Dark Gaia grabs Gaia Colossus. You must hit Perfect Dark Gaia's hands by pressing the correct buttons in time. Then it will tell you the button you need to press, and it should say x 60. You have short time to do this, but if you do Perfect Dark Gaia is dead. I just finished the game now.
