After Sonic, Tails, Amy and Knuckles have been captured by Neo Metal Sonic, Longclaw and the others call on the aid of Team Dark and Team Chaotix to rescue them. It was hard, but our heroes have successfully escaped their prison on the rebuilt Death Egg. Infuriated, Neo sends out his new troops, Metal Tails, Metal Amy,. Metal Knuckles, and the Shadow Androids, to find them. Join Sonic and the entire gang as they thrive to survive against Neo Metal Sonic's forces and hopefully find a way to defeat him. But when they were so close, Neo gains all seven of the Chaos Emeralds, becoming toe most powerful being in the universe!!! Then at the end, in their useless efforts to stop him, tragedy strikes very hard, and our heroes are in darker times than before. All hope seems to have died.
