It is not so bad, but I can't recommend it.
The campaign mechanics is very interesting, you control a group of 6 pilots in Iceland during a Russian Invasion (Tom Clancy Style), you can choose a pilot to control and you can change to other pilot at any moment, this is useful because there are simultaneous missions, this can be overwhelming at first but is simple.
The campaign is huge apparently, I played more than 5 hours and I cant see the end of this, the campaign is in real time starting a 8:30 hrs on day 1. and you can speed up the time 10x, I have played the equivalent to 16 hours in game time.
The graphics remembered me Ace Combat 3 Electrosphere. The gameplay is a little complicated in my opinion even after reading the manual, the success rate of the guided missiles is low even against non-moving targets, is possible to control the fighter with the mouse but I think this is too unconvenient in the dogfight, in addition you dont have ruddle control.
It works perfectly on windows 8.1 64x
In conclusion, a very interesting concept but not a very functional implementation.
