Improves on the original, which is something because COD 4 was/is the best FPS ever ! Modern Warfare 2 is PERFECT!!!!!!!
However there were a few minor problems there, host migration issues and lag were pretty bothersome to me. However, Infinity ward have really shown that they really are a step par excellence.
Host migration is featured in game and real time, and lag has been pretty much taken care of, even on a red bar, you can enjoy the game to its full extent.
This along with some new unlocks and callsigns, make this game the only game I need to own, and everyone else should too.
Single player story could have been put together well, but here it is pretty hard to get a grip on the story, as there is no flow in the storyline. But action packed moments that make you go WOW! are a plenty.
Graphics and sound have to be experienced. Bullet ricochet, grenade explosions, AC-130 Bombings sound as real as they look. This is the benchmark for all shooters. What difference 60 fps makes in a game, you know after playing Modern Warfare.
Controls are as smooth and responsive as they get. With no lag on them whatsoever.
This is THE game to play until...well until the next modern warfare...
