World in Conflict: Soviet Assault is a little difficult to score because there are two different versions of the game that cater to two very different crowds. On one hand, you have the $20 expansion pack, which adds six campaign missions and two multiplayer maps. The other version costs $30 and includes the original World in Conflict. There are clearly two audiences being targeted here, and the more loyal one seems to be getting the raw end of the deal. The six new missions are not worth $20, and aside from the six additional missions, Soviet Assault changes nothing else in the World in Conflict formula.
