World in Conflict: Soviet Assault is a real-time strategy game. The add-on adds new story missions and 2 new maps for multiplayer games: “The Wall” and “Fjord”. It was previously said that the game would feature water technology and maps for 10 players, however, in the end, these innovations were not implemented. The console versions were supposed to have the ability to use voice control to request reinforcements. In one of the missions in the campaign for the USSR, the player is given the opportunity to test a new type of incendiary bombs in battle, and in the first mission in Berlin, the player takes control of a small squad of special forces "Alpha", armed with AS "Val", but in the rest of the game this new type of tactical there is no support or troops. Soviet Assault interweaves the Soviet story campaign with missions from the original game. Without completing missions for the USA, further play for the USSR is impossible. Both campaigns form the story of the entire conflict in World in Conflict.
