I just got it today and so far it's f-ing hard. I'm on normal and the Russians just pour out of everywhere; it's insanity. I currently on the pine valley SP missions. Eventually too many Commies show up and I just get overwhelmed. Fun game so far though. Didn't know it was so short. I know that there is an american campaign, Europian, and finally one in Russia. Just what I heard, though. Does that sound about right? Don't give away any spoilers if it so. Just a yes.
