Accuracy is a mechanic in many games and in real-life. In the Modern Combat series, it is the hipfire and the invisible crosshair in ADS on all guns. The crosshair is much larger in Modern Combat 4: Zero Hour. The accuracy depends on the guns recoil and initial stats. If the gun has very high recoil then the bullets are very inaccurate. If the gun has very low recoil then the bullets are in a very tight cluster. If the player is moving or is continuously firing then the crosshair will be larger and accuracy will be reduced.
