There are three difficulty settings that affect the sensitivity of the controls as opposed to the intensity of the actual battles. When playing in Simplistic mode, you’ll get the easy-to-fly experience where quick moves, spins and turns make for a straightforward arcade-style shooter. Cranking it up to Realistic requires much more finesse and care. Turning incorrectly can easily put you in a top-spin that you’ll have to recover from and damage to the plane becomes a critical factor in keeping your bird in the air. Obviously, Simulation is for the experienced connoisseur of flight where even target locking is disabled, thus calling for bona fide skill. A different set of options also determines whether or not ammunition and fuel are unlimited if you’re feeling ballsy enough.
