World in Conflict Soviet Assault is a real-time strategy video game expansion pack developed by Massive Entertainment and published by Ubisoft. World in Conflict Soviet Assault brings a new Soviet campaign that is entwined with the original World in Conflict campaign, tying up the loose ends in the original campaign. The game is set in an alternate 1989 in which the Politburo of the Soviet Union elects to take military action to sustain itself, rather than collapse. Failing to achieve aid diplomatically, the Soviet Union invades Western Europe and the Pacific Northwest region of the United States.
