I've had this game since its original release and it's not grown on me. The story mode is good but that's it. Trying to keep track of the story is like trying to fit a jigsaw together with all the wrong pieces. The sound effects are very low quality and the graphics just aren't very sharp.
Call of Duty is all about multiplayer and this just doesn't deliver the same experience as Modern Warfare 2. Content wise, i preferred unlocking the guns as I grew through the levels as in previous Call of Duty titles, however I am not a fan of having to purchase: guns, attachments, camos, perks, grenades etc. etc.
The only part of this game that saves it from being a complete disaster is the Zombies mode which is terrific. The gameplay in Zombies is perfect and although there are quite a few glitches all in all this part is excellent.
In conclusion, this title of the Call of Duty franchise is a big let down compared to Modern Warfare 2 and I can only hope that Modern Warfare 3 is simply just a brilliant follow up to Modern Warfare 2 and that Black Ops is just a minor dent in what is a very good franchise.
