Remember how changing the character perspectives enables the audience to comprehend a story? This is something that Strike Force fully embraces. These four missions are a completely optional part of the story campaign that affects your overall ending based on whether you succeed. Seems simple enough, doesn't it? Well it is, but it's these small innovations that make a sequence of games like Call Of Duty feel novel again. Admittedly the missions themselves follow the tried and tested COD formula of kill 'X' enemies and advance to a certain point on the map (all are multiplayer maps, giving you plenty of time to learn). But therein lays the fun. There is a tactical element in knowing which squad (ranging between infantry, Dragonfire drones and A.G.Rs) to use at any individual moment and it's just plain old fun. If you disagree about this point then ask yourself this who doesn't want to be a walking tank? Nobody, that's who.
