Single Player Mode
The campaign is relatively short. In normal I was through in 5-6 hours, but not disappointed. I felt well entertained until the end. On the whole mercenary but was only interesting and veteran I'm still not quite through. If you play the game like that, and so I would recommend it to anyone, the season is fully in order. Incidentally gibts again the secret information that is really well hidden part.
For graphics do not need much to say. Anyone familiar with the other cods, the graphics will probably no longer tear off the stool, where the graphics are of course not bad. But nowadays there had better, for example Killzone 3 or Resistance 3. The control is as usual perfectly.
New to this installment of the series is the focus on a serious story that seems admittedly at times confusing, on the whole, but is a big step forward and I think binds to the end.
Multiplayer mode
The MP has always been the big plus in Call of Duty, and guarantees many hours of online fun. For the first time in Call of Duty you can by yourself or with a friend online or split-screen on the existing maps to fight bots. This is good training and you have the opportunity to finally try anything. Even the zombie mode can convince fully. Here the team skill is in high demand and for co-op friends like me is a real asset, online, split-screen or alone playable.
All in all, to say that I really had a lot of fun with the game and still have. There's just so many ways to engage over weeks and months with the game, do not have the other games. For me, Black Ops is also better than MW2, precisely because of the many co-op opportunities.
