In the past, Sunset City used to be a major merchant hub with several jewel markets. This ceased to be the case in the midst of the Eggman War as Dr. Eggman had his Badniks wreak havoc in the city. Some time after Eggman was defeated, the Restoration helped with reparations for the city. This did not last long as Eggman returned with his new Metal Virus substance and used it to infect several citizens of Sunset City, worsening the city's fate. After being contacted by Rouge to help aid the city, Sonic arrives on the scene of Sunset City's Zombot outbreak. He Spin Attacks several of them and begins to call out for civilians in need. Sonic soon finds himself surrounded by several Zombots but knocks them back with a spin kick. The hedgehog does not like the fact that Zombots keep grabbing onto him when fighting them already spreads the infection faster. Sonic is soon called by a civilian from a nearby building as he and many others were trapped in the building as a horde of Zombots blocked the door. Sonic prepares to hit the Zombots out of the way but is forced to quickly dart out of the way as bullets suddenly fly at the Metal Virus victims. E-123 Omega appears before Sonic, stating that heavier ordinance may be required in order to eliminate Eggman's resilient robots. Sonic protests that he should not do this as the Zombots are not regular Badniks but instead innocent people forcibly transformed by the Metal Virus. Omega ignores Sonic due to the Zombots' nature and origin being irrelevant to him; the only thing that matters to him is that they are robots created by Eggman. Sonic leaves Omega be as the Zombots themselves were durable enough to handle Omega's artillery.

Rouge flies overhead and asks Sonic and Rainbow to guide the citizens to the Grand Gold Flicky Hotel where they are organizing survivors. Sonic does so and is asked by one citizen if they should thank Omega for his help. Sonic assures him that Omega is not the type of person who needs it. With this, Sonic begins to knock several Zombots out of the way to clear a path to the hotel. He arrives at the front of the hotel where the city's defense force are using Burst Wispons against incoming Zombots. Rouge gives the order to one of the officers to gather several other officers to guard the rear as she spotted another wave coming in from the east. She then turns to Sonic and thanks to him for his help. Sonic tells Rouge that his infection is still currently manageable and Eggman has begun to lose control over the Zombots. This annoys Rouge as she did find the assault sloppy anyway. Sonic asks where Shadow is and Rouge responds that he is picking up transport for the survivors. The duo soon hears a cry for help from uninfected villagers trying to get inside the barricade. Sonic nearly reaches for the villager in front, only to remember that he is infected. He instead creates a vortex to knock the incoming Zombots back. He tells the defense force that more Zombots were coming and not following any sort of plan. Sonic then picks up two Zombots and takes them away from the hotel, not wanting to lose any more friends to the Metal Virus.

"How handing Omega?" Rainbow asked.

Too many targets. Not enough bullets, Enemy is advancing from both directions.

"Both directions?" Rainbow took the skies seeing the horde of Zombots. "I see them! Sonic tried to cut them off! Omega, hold the line!"

Acknowled. Created a wall of bodies.

"Not what she said..." Sonic retorted then notice something. "What the...?"

Sonic witnesses several Zombots being rammed into by an object on the bridge, east of the hotel. It is revealed to be a military truck that was being driven by Shadow.

"Couldn't find a bigger truck!"

"Shut the hell up," Shadow snapped.

"Dude, I was kidding."

"This is all your fault if I had destroyed Eggman in Windmill Village, none would be happening!"

"It's not his fault!" Rainbow came to his side. "Some creep named Starline made him evil again! Nobody could've seen that coming!"

"Excuses!"

"I'm already infected!" Sonic showed him.

"It's what you deserve."

Though he finds frustration with Shadow, Sonic runs off to clear his infection and tells Shadow that he would be able to run the Metal Virus off as well should he get infected. Shadow tells Omega to safeguard the truck while Rouge oversees the evacuation of the uninfected. Omega accepts this as it would bring him more targets. The robot asks Shadow what he will do in the meantime and he responds that he will destroy Eggman's army. Rouge and the defense force help guide the uninfected citizens into the truck as Omega continues to fire at a wave of Zombots. Rouge oversees Shadow's fighting, believing he is being reckless.

Shadow dives right into the Zombot horde, believing that he cannot be infected as the Ultimate Lifeform; he does commend the infected for their resilience as he fights through them.

Meanwhile with Sonic and Rainbow

"Are doing okay?" Rainbow asked.

"Doing fine Dash," Sonic replied. "I'm used to getting tired, I guess being on the move is starting to take its toll."

Both the hedgehog and the Pegasus looked over the city.

"This is looking bad...Charmy...Cheese... Chocola... who knows how many others around the world..."

"Sonic look at me," He turned to Rainbow. "I know this looks dire but get hold of yourself, just because one jerk did the wrong thing doesn't mean you did the right thing. Mr. Tinkerer deserved his second chance. Right now, we got get back there and do what we heroes do best!"

"Your right! Save the folks!" Sonic gave her a thumbs-up and both headed back.

Back in the city, Shadow continues to fight back against the Zombots. After throwing one Zombot away from him, he discovers the Metal Virus liquid on his left hand.

"That's impossible..." Shadow sees the liquid in his hand.

"Shadow! Run!" We'll hold them!" Rouge told him to retreat.

"I don't run!" He refused to fall back and continue to fight.

"Omega! Give Shadow cover fire!" Tempest told him.

Negtive Targets advancing to rapidly sustained fire to protect the truck.

"Amy? Twilight?" Rouge reached for her comm. "Send whoever you can to Sunset City, Now, The situation just went from manageable to disastrous."

"Check your fire, Omega!" Sonic exclaimed as he and Rainbow Dash dodged the gunfire.

"Sonic! We need you over there to handle Shadow!"

"Will do!" As he ducks underneath the truck. "What does she means by that?"

"I think I do look out!" Rainbow warned him but Shadow pinned him against the truck.

"I get it now," Sonic understands what Rouge said. "Is it my turn to say 'I told you so'?" He asked an infected Shadow.
