Look Sensitivity

In the controls menu there is an option to adjust the Look Sensitivity.

Advantages of a high setting

 * It makes it fast to track a moving enemy in close combat.
 * You can turn around fast when you have an enemy behind you.
 * With a weapon like Shotgun you can easily shoot down the driver of a fast and close moving vehicle (Like jumping over a Ghost trying to run you over and fire straight down on the driver).
 * In Halo 2, due to its enormous auto-aim, sweep-sniping (the act of moving the reticule of the sniper rifle across an opponent's head giving an instant headshot) will benefit greatly from an increase in sensitivity.

Advantages of a low setting

 * You get accuracy in sniping.
