The single player is as good as ever but the multiplayer is laggy and below par for a COD game.
The single player on the other hand is great, and creates a varied atmosphere and an intriguing story. The occasional hiccup will occur like have a mission where the only way to find out what to do is listen to a conversation while 30-40 guns and launchers are being fired around / at you, or the game freezing for about 10 seconds when an in-game trophy is earned.
contrary to the GS review i found the sound effects very unbelievable. Most riffles sounded like they already had silences on them and grenades thrown only a few feet away would give off a barely audible 'pop' sound.
