Seen it all Before
This is probably the last of the big selling FPS's I will buy (The other being the Battlefield series). I don't think it is the game that is flawed, but rather that there is nothing either of the series can do to become fresh again. Quite simply these games are predictable and there is nothing worse.
The upside is that survival mode will guarantee hours of "fresh" gameplay, but im afraid after that the COD series has managed to run out of steam. 4 stars for the hours of controller bashing ive wasted on it.
