The game is fun, but is nothing different. You will have a good time but you could stay playing Black Ops.

I have played the game for several hours and at first I felt so incredibly disappointed because, I don't want to sound cliche, but I felt like I was playing the new map pack for CoD.
Once I stopped fooling my self about expecting something new, I started to enjoy the game I have been playing for 5 years. This is truly no different. Graphics are at the level of black ops but the sound is better. The multiplayer maps are generally small and very intricate. Much less open than previous instalments.

In general, the game is the same, same fun, same thing. If you don't have the $65 to spare without sacrificing other games stay with black ops or get Skyrim or Battlefield 3 if you want to spend that money anyways.

It will be fun, but you can have the same fun playing black ops. I'm very honest here.
