A very nice campaign. I'm not myself that interested in long storylines so i didn't pay much attention .. but its probably a good thing that its there: Its perhaps what makes it for some - and the rest, like me, can just skip it or.
There is nice sense of things going on around you, nice "intro's", and some good missions. A bit on the easy side. I managed to complete all missions on my first attempt but its nice to feel like pro sometimes and not allways get pitted against impossible odds. I like the weather and the times the missions take place in.
If i was to change anything, i would make them just a little harder. Worse weather or a little more resistance. Or both
