Reticle

A reticle is a shape superimposed on an image that is used for precise alignment of a device. Crosshairs are most commonly represented as intersecting lines in a "+" shape, though many variations exist, including dots, posts, circles, scales, or chevrons. The reticule in the Halo games is the primary means by which players (and Spartans and Marines) aim their weapons. It is located in the center of the screen and changes based on which weapon you are wielding.

About the reticule

 * Normally blue in color, the reticule will change to red if moved over an enemy or green if moved over an ally. Note that if the enemy is far enough away for that particular weapon, the reticule will not turn red. This is often a good indicator of an enemy being out of range. Zooming in (if your weapon has a scope attachment) may well make the reticule red if moved over a previously out of range enemy.
 * If the weapon you are wielding is capable of a headshot, and the reticule is moved over the head of an enemy, a small dot will appear in the center of the reticule (with the exception of the Beam Rifle). This can be useful to aid aiming when delivering that quick kill is what you want.
 * When dual wielding weapons, the two reticules for the two different weapons you are wielding will be laid on top of one another. If you are dual wielding two of the same weapon, the reticule will be no different than if you were wielding one of that weapon.
 * In Halo 2, the Rocket Launcher is a special case in terms of reticule, it will change when moved over an enemy vehicle, indicating the ability to "lock-on" to that vehicle. See the rocket launcher page for more information.

Tips on using the reticule

 * While the reticule is primarily for determining if you are aiming well or not, it can also be used to determine the spray of your weapon. Weapons such as the sniper rifle are very accurate and do not have a spray pattern or area of effect, so the reticule is very small, but weapons with a larger spray, such as the shotgun or the Warthog Turret have much larger reticules. If the torso of an enemy fully occupies your reticule, you can be sure that an instant kill with one of these weapons is a distinct possibility. This also applies in general, usually the optimum range for a weapon is when the torso or head of your opponent fully occupies your reticule.


 * Remember also that the reticules of different weapons are different for a reason. Weapons such as the Brute Shot are much easier to aim if you know how to use the reticule to help you to aim it.


 * The color of the reticle can also help you determine if the weapon is in range of the Auto-Aim. If your reticle is not red, the magnetic targeting will not work, making it harder to aim. Weapons like the Battle Rifle can achieve greater auto-aim range when scoped.
