However, dark clouds are gathering in the East. The communist-led Russy Federation is mustering troops on its western border, preparing to enter the war.

Any escalation of violence at this point may lead to new conflicts, plunging the world into a devastating global war.Will the Empire eventually emerge victorious from its struggle, or will it crumble in the face of superior enemies and radically different ideologies?
