If Modern Warfare 2 was actually a game about modern warfare, it wouldn't be half as much fun as it is. Heartbeat-detecting weapons are not deployed on any real-life battlefield, R&R does not involve slalom snowmobile races in which drivers shoot each other in the face, and two soldiers versus 40 snipers is not a scenario from this or any era. Importantly, it's not a scene from a movie, either. Leaving the Black Hawk Down-isms to a secretive campaign, the new Special Ops modes are 100 per cent videogame. No wonder this is such a bogeyman on the Christmas schedules. Whether you're a firstperson shooter or not, just being an action game puts you in its sights.
