I've been playing this campaign, and I have a mixed opinion on it.
There are things about the campaign that are done fairly well, but there were some things I didn't like.
The main thing I would say about this campaign is that it is quite difficult, and is not for the more casual Arma player/gamer.
The mission, while singleplayer, is designed very much like a coop mission for 3-6 players, quite a few enemy units, units are very aggressive, and seemed to be scripted with reveal player commands.
So if you're looking for a challenging campaign, check it out, if you're a more casual player, this may not be for you.
