'''Energy shielding''' is an advanced defensive technology making use of a field of energized particles that wraps around a surface, which deflects objects that attempt to impact the surface. Most energy shields are able to deflect various forms of damage, from material projectiles to [[directed-energy weapon|directed energy streams]]. Several [[United Nations Space Command|UNSC]], [[Covenant]] and [[Forerunner]] [[:Category:Vehicles|vehicles]], [[:Category:Equipment|devices]], and [[armor]] systems make use of energy shielding to protect users from harm.

The Covenant make extensive use of energy shielding technology. Nearly all Covenant starships larger than a [[dropship]] use energy shields and several ground-based structures use shields as well. Many Covenant warriors are equipped with energy shields.

Many Forerunner constructs make use of energy shielding. Standard Forerunner [[Sentinel]]s are encased within an ovoid energy shield that can withstand moderate damage, while the [[Onyx Sentinel|much more powerful Sentinels]] from the [[Onyx]] [[Shield World]] possess spherical golden shields that activate whenever a fast-moving projectile approaches. The larger [[Enforcer]]s possess three-part energy shields that protect their photoreceptors and chassis from frontal assault, but do not protect against attack from any other angle. The majority of Forerunner energy shields seem to consist of a translucent bubble composed of hexagonal patterns, as opposed to the wraparound shields typically used by the Covenant and UNSC.

==Gameplay==
*In ''Halo: Combat Evolved'', the status of the energy shield is shown at the top-right corner of the screen above the health bar. In ''Halo 2'', it is in the bottom-left above the motion tracker. In ''Halo 3'', it is in the top-center of the screen. In ''Halo: Reach'', it is shown in the top-center of the screen above the health bar.
*The placement of the player's shield meter has undergone several changes over the years:
*In [[multiplayer]], players can have 50%, 100%, 200%, 300%, 400%, 500%, 1000%, or 2000% shield strength, or none at all. In ''Halo 2'' and ''Halo 3'', both Elites and Spartans have the same amount of shielding; in ''Halo: Reach'', Elites have more shielding (but less health) than Spartans. A player's shields can be further augmented if they pick up an overshield.
**In ''Halo: Combat Evolved'', the status of the energy shield is shown at the top-right corner of the screen above the health bar.  
*In ''Halo: Combat Evolved'' under standard game settings, energy shields begin regenerating five seconds after last being hit and take four seconds to fully recharge from a total drain.
**In ''Halo 2'', the shield meter is in the bottom-left above the motion tracker.  
**In the Campaign, the shield regenerates at a fixed ratio of shield points per second, and the low shield tone activates at a fixed shield percentage. Because the difficulty affects shield strength, it takes 8 seconds on Easy to recharge from a full drain, which is so long that the recharge sound plays twice; the low shield tone plays for the first two seconds of regeneration.
**In ''Halo 3'', the shield meter is in the top-center of the screen.  
**In ''Halo: Reach'', the shield meter is shown in the top-center of the screen above the health bar.
**In ''Halo 4'', the shield meter is again shown in the top-center of the screen, but there is no visible health bar.
**In ''Halo 5: Guardians'' and ''Halo Infinite'', the health bar is visible and the shield meter appears above it once more.

*In ''Halo: Combat Evolved'', during the level [[Two Betrayals]], energy shielding was used to overload [[Installation 04]]'s pulse generators.
*In ''Halo: Combat Evolved'', during the level [[Two Betrayals]], energy shielding was used to overload [[Installation 04]]'s pulse generators.
*In ''Halo 2'' under standard game settings, energy shields begin regenerating 4.25 seconds after last being hit, and take 1.75 seconds to fully recharge from a total drain.
*The amount of time it takes for the shields to regenerate in each Halo game has changed:
*In ''Halo 3'' under standard game settings, energy shields begin regenerating 5 seconds after last being hit, and take 2 seconds to fully recharge from a total drain.
**In ''Halo: Combat Evolved'' under standard game settings, energy shields begin regenerating 5 seconds after last being hit and take four seconds to fully recharge from a total drain.

*In ''Halo 4'', during the level [[Forerunner (level)|Forerunner]], energy shielding was used to enhance a {{Pattern|Karo'etba|Ghost}}'s boosting.
*In ''Halo 4'', during the level [[Forerunner (level)|Forerunner]], energy shielding was used to enhance a {{Pattern|Karo'etba|Ghost}}'s boosting.
*In ''Halo 4'', during the level [[Shutdown]], energy shielding was used to generate an EMP which overloaded the communication network's carrier wave generator.
*In ''Halo 4'', during the level [[Shutdown]], energy shielding was used to generate an EMP which overloaded the communication network's carrier wave generator.
*In ''Halo 5: Guardians'', when a Spartan is revived after being downed, they and the reviver will be granted an [[Overshield]] that drains over time.
*In ''Halo 5: Guardians'', when a Spartan is revived after being downed, they and the reviver will be granted an [[Overshield]] that drains over time.
*In ''Halo Wars'', most of Covenant vehicles are equipped with energy shielding, while for the UNSC, it is exclusive for Red Team.
*In ''Halo Wars'', most of Covenant vehicles are equipped with energy shielding, while for the UNSC, it is exclusive for Spartan units, including [[Red Team]].
*In ''Halo Wars 2'', UNSC base defenses can be equipped with energy shield if player upgrades R&D leader power. Some vehicles are also equipped with energy shielding.

* The health and shield points in ''Halo: Combat Evolved'' are higher than those in the subsequent games. In ''Halo: Combat Evolved'', both health and shield are given 75 points. On the other hand, there are only 45 health points and 70 shield points in ''Halo 3''.{{citation needed}}

* Until ''Halo: Reach'', shields regenerating were depicted by a wave of energy traveling up the wearer's body. To better fit with the treatment of shields as an energy field, the animation was changed to bands of energy slowly wrapping around the wearer then fading away.

* In ''Halo Infinite'', energy shields underwent an artistic redesign. Spartan shields now feature a hexagonal pattering, while Brute energy shielding is made up of horizontal lines.
