Named Sonic & Tails 2 in Japan, as Sonic Chaos was called Sonic & Tails there. Well, the story, is yet another world domination thing by Eggman, only this time like Sonic 3, he has the help of Knuckles, that god darn fool! That 'trusty' echidna nabbed all the Chaos Emeralds and has legged it. Sonic, not too happy, chases after Knuckles, with Tails close behind. On top of this, Eggman got some help from good old Nack the Weasel, or Fang the Sniper in Japan. He keeps guard of the Emeralds, making sure Sonic and Tails won't get to them, while Knux will just stop them advancing. Eggman must be a happy boy. Not for long though. Can Sonic boil the rotten egg again? We will see...
