The '''bubble shield''' {{ZClass|4190|Temporal Protective Enfolder/Stationary Shield|TPE/SS}},{{Ref/Reuse|universe}} is a piece of deployable equipment. It is [[Forerunner]] in origin, but the [[United Nations Space Command]]'s [[Office of Naval Intelligence]] manufactured a number of the devices based on discovery of those formerly used by [[Warrior-Servant]]s.{{Ref/Reuse|universe}}

==Overview==
[[File:Bubble Shield.jpg|thumb|left|200px|Late-war deployable shield modules created a gold, dome-like protective area for approximately 20 seconds when activated.]]
===Design details===
"Dissipative"-style bubble shields are a technology originally of [[Forerunner]] origin. They were used by the [[Warrior-Servant]]s and various forms of [[Sentinel]] for protection, and later reverse-engineered by both the [[Covenant]] and [[Office of Naval Intelligence]] to form crude copies for use as battlefield deployable equipment.{{Ref/Reuse|universe}}

The bubble shield design used by humanity and the Covenant consists of an emitter capable of projecting a translucent, slightly white/gold tinted protective sphere sphere of interlocking hexagonal force enfolder elements around the user.{{Ref/Reuse|universe}} The shield itself is similar to a [[Wikipedia:Geodesic dome|geodesic dome]], made of tessellating hexagons. The shield protects against bullets, explosions, [[laser]]s, [[plasma]], flames, [[grenade]]s, and other projectiles. Vehicles and personnel, however, are still able to pass through it. After approximately 20 seconds have passed since activation, the shield will collapse and the generator self-destructs. Heavier stationary weaponry, such as the {{Pattern|Shuku|sentry turret}}, are capable of overpowering or firing through the shield.{{Ref/Map|H3|Snowbound}}{{Ref/Book|Enc11|Page=345|Detail=Although the Automated Plasma Turret caption pictures a {{Pattern|Zo'op|Weevil}}, the descriptive text refers to the Snowbound sentry guns.}}

===Development history===
<!--The EVG states that humans made theirs based on captured Covenant examples. Waypoint states the opposite. This is the only way this can make sense.-->
The bubble shield has a storied developmental history among the Covenant and the UNSC. The original designs for the bubble shield are based on Forerunner technology, used by the [[Warrior-Servant]]s and some forms of [[Aggressor Sentinel|Aggressor]] and [[Protector Sentinel (Shield World 0459)|Protector Sentinel]].{{Ref/Reuse|universe}} These devices were crudely reverse-engineered by the Covenant, with examples themselves captured by the UNSC and used as the basis for the development of a bubble shield of [[human]] make during the later years of the [[Human-Covenant War]].{{Ref/Book|Id=EVG|EVG|Page=47}} During the [[Fall of Reach]], many of the ONI prototypes for the deployable bubble shield were captured by Covenant forces and were crudely copied for use by loyalist [[Jiralhanae]] forces in the war's final months - particularly the [[Battle for Earth]] and [[Battle of Installation 00]].{{Ref/Reuse|universe}}

ONI research into bubble shield technology also resulted in the development of a [[MJOLNIR Powered Assault Armor]]-compatible [[Armor abilities|reusable armour ability]] known as the [[drop shield]].{{Ref/Book|Id=Enc11DropShield|Enc11|Page=355}} Manufacture of ONI-approved bubble shield devices continued until [[2555]], at which point they were discontinued and development efforts were refocused toward MJOLNIR-compatible emitters.{{Ref/Reuse|universe}}

==Operational history==
Bubble shields were used by the [[Warrior-Servant]] forces of the Forerunner [[Ecumene]] to provide temporary battlefield fortifications, with similar systems employed as the standard energy shielding mechanisms of various Sentinel classes.

During the [[Human-Covenant War]], [[human]]ity were able to leverage bubble shield technology stolen from Covenant derivatives of the Forerunner originals in a number of forms. One such device was used by [[Blue Team]] during [[Operation: WARM BLANKET]] in [[2544]], to safely secure their boarding of the Covenant carrier ''[[Resplendent Fervor]]''.{{Ref/Film|HLeg|Episode=The Package (animated short)|The Package}} Another such system was later featured in a number of the [[Project HRUNTING|HRUNTING]]/[[Project YGGDRASIL|YGGDRASIL]] development program prototypes including the [[HRUNTING/YGGDRASIL Mark I ADS|Mark I ADS]] and select [[Reactive Cyclops|refit packages]] for the [[HRUNTING Mark III (S) Cyclops|Mark III [S] Cyclops]].{{Ref/Film|HLeg|Episode=Prototype}}{{Ref/Game|HW2|[[Reactive Cyclops]] Blitz unit}} Forms of bubble shield technology continued to be developed and used by UNSC forces through the late-war, with ONI developing the drop shield armour ability package based on the same operating principles, later used during the [[Fall of Reach]].{{Ref/Reuse|Enc11DropShield}} Many of these designs were stolen from Reach by Covenant forces, and further developed and used by the Brute loyalist troops during the final weeks of the war.{{Ref/Game|H3|Bubble Shield in-game equipment}}{{Ref/Game|H3ODST|Bubble Shield in-game equipment}} Due to their size, mass, and relatively short power cell duration, along with low rates of production, Bubble Shields saw very limited use during the last stages of the Human-Covenant War.{{Ref/Reuse|universe}}

During [[UNSC Tactical Simulator|simulations]] of the [[Battle of Installation 03]] and [[Battle of New Phoenix]] a [[Unidentified Spartan-IV|Spartan-IV]] utilized a [[armor abilities|version]] capable of allowing the user to fire weapons at targets while remaining inside the shield.{{Ref/Game|HSS|Bubble Shield in-game equipment}} By 2555, production of ONI produced bubble shields was halted in favour of focus on MJOLNIR energy shielding,{{Ref/Reuse|universe}} though the existing prototypes continued to see use as late as [[2558#January|January 21, 2558]], in which [[SPARTAN-G059]] deployed a bubble shield against [[Avu Med 'Telcam]] to block his {{Pattern|Vostu|carbine}}'s rounds during her [[Assassination of Avu Med 'Telcam|assassination mission]].{{Ref/Comic|HTFS|Story=Knight takes Bishop}}

As of [[2559]], bubble shield technology has been leveraged by the forces of both {{UNSCShip|Spirit of Fire}} and the [[Banished]] during their [[Second Ark Conflict|war for]] control of the Ark.{{Ref/Game|HW2|Reactive Blitz units}}

==In-game information==
===''Halo 3'' and ''Halo 3: ODST''===
[[File:Bubbleshield gx1-1.jpg|200px|thumb|Comparison between deployed and undeployed bubble shield.]]
In the [[campaign]] of ''[[Halo 3]]'', [[Jiralhanae|Brutes]] deploy bubble shields often. At least one or two Brutes in a Covenant [[pack]] always have a bubble shield on hand. Brutes generally activate their bubble shields immediately when taking fire or when feeling threatened. Unlike the [[multiplayer]] "[[shield door]]s", vehicles are able to pass through the bubble shield. Damaging the shield generator itself in the bubble's enclosure will cause it to explode, and the shield will collapse upon detonation. Upon reaching its energy limit, bubble shields will make a high-pitched sound prior to overloading and exploding. In ''[[Halo: Spartan Strike]]'' the bubble shield can be used repeatedly with a duration of 8 seconds and a cooldown of 24 seconds.

;Disadvantages
* Enemies can enter the shield freely.
* The bubble shield only lasts about 20 seconds. In combat, however, this is more than enough time to regroup and recover.
* If either the player or an enemy throws a grenade inside the bubble shield, it stays inside and will more than likely kill almost everyone in the shield at that time. This strategy is most effective with [[Type-2 spike grenade|spike grenades]], as the spikes will bounce around and shred anything inside the shield.
* The generator is very delicate, and if shot from the inside, it will quickly explode and destroy the bubble shield.
* Vehicles can also enter bubble shields. Therefore, you can run somebody over while they are still in the bubble shield.
* The bubble shield can be affected by other equipment if thrown within the shield's proximity. For example, if an opponent throws in a [[portable gravity lift]] near the generator, the gravity lift can raise the shield generator up, leaving anyone previously inside the shield defenseless. Additionally, effects from equipments can also be limited in the shield; if a [[regenerator]] is thrown inside the bubble shield, only those within the shield are affected. Likewise, if a [[power drain]] is thrown inside an active bubble shield, the disabling effects of the power drain are contained within the bubble shield.
* The bubble shield can be knocked away by throwing a power drain or [[radar jammer]] at the generator, causing both objects to roll, and leaving anybody previously inside the shield exposed.

== Trivia ==
{{Linkbox|gallery=yes|gameplay=yes}}
* An early form of the bubble shield was used in the [[Starry Night|original teaser trailer]] for Halo 3. It is shown being used by [[John-117]] to protect him from an incoming [[Zurdo-pattern Wraith|Wraith]] mortar. In the teaser trailer, the bubble shield looked like a type of grenade, leading to rumors that it would be one of the new grenade types.
* The bubble shield is capable of negating the effects of a [[Kill Ball]], allowing players to go inside the ball.
* When deployed on an Elephant, the bubble shield does not work as intended- high-powered weapons such as the Spartan Laser will shoot right through, killing the user inside. However, five or more bubble shields will protect players inside its dome.
* In ''[[Halo: Spartan Strike]]'', only Elite Majors are issued with bubble shields, while the player can equip it as default on certain missions.
