Good game, some flaws but still that CoD feeling.
In Black ops campaign you take the roll of Alex Mason a young man in the military who is abducted. As Mason is abducted he has to tell his captures info about his military missions. Through flashbacks you play as Mason battling his way through war. I personally have nothing to say about campaign mode except that it is to the point, therefore, mediocre.
Now lets talk about multiplayer. One thing I wanted to point out is the CoD points. Are they really necessary? I liked the old way, unlocking guns and other stuff as you work your way through the ranks. But other than that multiplayer is pretty good. The map-packs are awesome, and most importantly there is no problems with the controls.
Bring all this together and you have a pretty good game.
