The Soviet campaign follows the same basic storyline, but from the CCA's perspective. Starting on Venus, the Soviets are hounded off the planet by an NSDF unit called the "Black Dogs". They travel to Io to capture one of the Fury relics, but after the Black Dogs destroy their main base, are forced to regroup and reestablish a foothold. Once this is achieved, the production of Fury units begins, and the CCA uses them to wipe out the Black Dogs in the final mission, just before the Furies turn on them. The Soviet campaign is the shorter of the two, as the NSDF missions were intended as the main game. However, the CCA missions are meant to be more difficult, and the player must manage the full technology tree from the beginning, instead of being gradually introduced over the course of the campaign.
