This game is all about the campaign. Play it. Play it again. Play it again and again and again. The story is excellent, the voice acting brilliant, the levels of destruction are massive and the AI relentles! With most missions often offering at least one, sometimes as many as three, "side missions" which are issued as the the battle rages completing every part of every level is that most demanding of tasks. See the big picture, control the battle at the point of contact, manage the reserves and make sure you don't let a single enemy past!
