It's a pretty good FPS game. Basic gameplay elements graphics, controls, and network connectivity (offline) are no problem. But there doesn't seem to be any special over 4 stars.
In addition, I think that a game that combines a story that cannot be played multiplayer, which is the biggest advantage of an FPS game, and an offline game, will develop into a better game.
If it's a simple game where guns and grenades and Classic FPS Games, COD M seems to be enough already.
