"H.A.W.X.'s problem is that there's just not enough variety. Your time in the cockpit is over and done in just under eight hours, and at the end of it, you'll only have earned about half of the experience needed to unlock all the game's extra planes and weapons. Compounding the problem of unlocking is that most of the big ticket challenges will have been completed by the time you've finished the campaign. With several thousand experience points separating each level, the 5-50 points earned per downed enemy fosters a monotonous grind which will turn most players off. Even then though, there isn't a whole lot to do with all of those sweet unlocks.
H.A.W.X. desperately wants to be a great game. It gives you these beautiful environments, tons of fun to control fighter jets, little elements that scream "Love me!" Then a handful of hours have passed and you've seen all there is to see in the campaign and despaired at the thought of slowly grinding through the last experience levels. You had a little bit of fun, but you can't help but think it could have been so much more. "
