As a veteran of the Call of Duty and Modern Warfare series, this part could not be missing. Normally, I buy video games a few months after release, because the disappointment is not so great, because you have only just paid half. In Call of Duty, I had me about it but never worry about. Here I have always slammed right after release - of course, to have a good start in multiplayer - and has not been disappointed. The story builds naturally right at the end of Modern Warfare 2 and starts as one would expect with all-out action and the state of emergency. It is war, everywhere, of course, between the Americans and the Russians. However - as shown in the course of the story - is the cause of the good old Makarov, the one somehow not yet got hold of. The gameplay is typical Call of Duty, here has changed little or nothing. A new feature in single player is the "hybrid visor", it allows the simultaneous wearing of holograms and ACOG optical sight that I like very much. The campaign is perhaps to say it again crashes a lot and of course this is also something in the air.
The multiplayer is okay. I think he's not as good as in MW2, you can play it however. The maps are all a bit designed for CQC, which makes a lot of fun with the UMP or MP4. For me, as a sniper, unfortunately a bit too small, but because it has a large arsenal of weapons at your disposal, you'll quickly find replacement and is always forward 'here.
Conclusion: For fans of the MW and Call of Duty series is a must, it maintains, the story is as always good. Buy.
