English manual transcript
One day, while wandering around, Sonic caught a glimpse of something on Emerald Beach. What he saw upon reaching the Beach was a battered robot. Although he tried to communicate with it, there was barely a response.

Then he hit upon the idea; "I know who can fix this robot - Tails!" However, soon after, Shadow appeared wanting the robot.

"So you already have it. Give me the robot, Sonic" said Shadow.

"What if I say no?" Sonic responded.

It seems another storm is starting to brew.

Game © SEGA/Sonic Team

The Death Egg from Sonic 2 and Sonic 3 & Knuckles returns as Eggman's main battleship.

E-102 Gamma in this game is most definitely not the same E-102 Gamma from Sonic Adventure. It is powered by chaos emeralds/shards, not an animal as in Sonic Adventure.
