Robots were ready to punch through enemy lines. Dr. Eggman had found out that the Master Emerald had been retrieved, and the Soviets have set up shop on Angel Island. He decided to let them keep the island for awhile; he had another fight to deal with.
"Be ready, my creations! The day of my victory will come!" Eggman said, with a grin. "I will be unstoppable, when my ultimate weapon is complete."
As the days go by, more battles are fought and the outcomes are mixed. So far, Eggman is winning.
