Plot
Dr. Eggman kidnaps a group of G.U.N soldiers, including Topaz, and steals a map of the lost continent of Murasia. Pursuing him, Sonic and the gang find him planning to activate a hotspot located beneath an island that is the last remnant of Murasia. Engaging Eggman's Giant-Makan warship, they are joined by the Eggfort 1, which has been recovered and refurbished into the G.U.Nfort. The G.U.N fort sets out to destroy Eggman's vessel, not caring for the prisoners aboard. In desperation, Eggman tries to fire the Giant-Makan's main weapon, driving off the G.U.N forces. Sonic and Knuckles work together and destroy Eggman's ship. Eggman, his allies, and Sonic's friends then land on the island.
