Due to the Earth condition after Sigma spread the virus, most of the Reploids that possessed the parts to enhance the Enigma had already gone Maverick. Unfortunately, as Enigma was too old, the Maverick Hunters plan on using the remaining time before the collision to gather upgrades to enhance its chance of success. The Maverick Hunters plan on using the only available weapon in stock, a large particle cannon, Enigma, to sacrifice Eurasia for the sake of the planet. Within 16 hours, Eurasia would crash and cause great destruction, in the worst case extinguishing all life from the planet. Sigma hired a bounty hunter to take control of it, scatter a virus in the colony and use its artificial gravity systems to set it on a collision course towards Earth.

As it was quite old, it was planned to receive extensive renovation. The repair of the space colonies damaged during the Great Repliforce War was almost complete, the only space colony remaining being the giant colony Eurasia located in a Lagrangian point.

Eurasia (ユーラシア ?) is a gigantic space colony that played a very important role in Mega Man X5 and X6.
