Been there done that got,got killed and annoyed by hackers and lag.Disapointment.
First off Graphics are done on the same engine as Modern warfare 2 but with litlle improvement,which is enough.Gameplay is the thing that is same but disguised,campaign continues the MW2 story and is really short(and good,nothing special) which is expected because the aim of the game is based on Multiplayer which is ruined nowadays because the servers are full of hackers,plus u will die alot because of the random enemy spawing behind u and instant killing u,the lagg is always present which will freeze u and before u know it u will be killed so the next thing i will see is killcam.It seems like they didnt learn anything from the previous game errors.
Overall the game is average,story is short and good graphics are good,gameplay is the same thing copyed over and over,Multiplayer is such a let down and will get on your nerv,so i will recommend this game only to MW fans not Cod fans in general.
