"Modern Warfare 2 takes place 5 years after where we left off and goes about the first stage in a very similar manner. However, this time you are not treated as a rookie but more the slightly experienced soldier who can show the rookies a thing or two about war.
It looks like Infinity Ward had improved the engine's ability to render vast amounts of enemies on screen at any one time and the Washington DC battle was a perfect example of this, you really did feel overwhelmed by the sheer number of enemy infantry and vehicles moving around.
The end sequence is becoming a Modern Warfare staple and while this story is pretty neatly wrapped up there is enough left in the story to easily justify a third in the series."
