This campaign is specifically made for those who are interested in what DCS has to offer. For no money whatsoever. YES, the sim itself is free and the Su-25T is one of two aircraft included for free (the other one being a civilian Mustang). Now some might say the Su-25T isn't "kewl" or "rad" enough. Because it's one of the oldest DCS aircraft and because it's too easy in the handling or such. Well, I suppose it isn't much of a challenge if you only fly in fine weather, at mid-day and over a flat desert. In this campaign however, there's none of that. You will learn to cope with adversity AND learn to handle this brick...in the worst of conditions. If you manage to finish this campaign, you already have what it takes to fly any other aircraft in DCS. Trust me on that. DIFFICULTY: Beginner tough guy
