How does the single player campaign play out? How many missions?
EA Pacific has designed a 21-mission single player campaign that will unfold in a seamless, linear story, told in part by each of the three sides. The story unfolds in three campaigns in the order of China, GLA and the USA. However, while playing the campaigns in the set order will best tell the story of the game, it is not mandatory and you will be able to select any campaign to play through.
