There are also spec ops for singleplayer PS. I play the cracked version. But going to buy a legit one soon Ah. So these level u r talking about is in co-op And can a RU version play with US ?
I play legitly on the spec ops on MW3. In solo, on the hardest level, baakara or something, I'm in the top 1600s (which means I got to wave 12!)
