Z-4190 bubble shield

Were you looking for Drop shield?

Template:Weapon Infobox The Z-4190 Temporal Protective Enfolder/Stationary Shield (Z-4190 TPE/SS), commonly referred to as the bubble shield, is a personal defense device. 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-Servants. Even the Covenant reverse-engineered crude copies based on captured ONI prototypes.

History

The Covenant's version of the bubble shield created a gold, dome-like protective area for approximately 20 seconds when activated.

Historically, the ‘dissipative’-style deployable energy shield system of the bubble shield is Forerunner in origin. Warrior-Servants utilized such a system to generate temporary fortifications using a sphere of interlocking hexagonal force enfolder elements, similar to those used by Sentinels and Protectors. The technology was eventually discovered by ONI in the twenty-sixth century and was repurposed for use by the UNSC Armed Forces in the Human-Covenant War. In 2544, Spartan-II Blue Team used a bubble shield during Operation: WARM BLANKET. HRUNTING/YGGDRASIL Mark I ADS suits utilized a form of bubble shield for protection. 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.

The drop shield is an advanced iteration of the bubble shield that was developed by the Materials Group for ONI's Beta-5 strike teams. Drop shields saw usage during the Fall of Reach. After Reach was defeated, Covenant forces recovered and copied ONI's shield prototypes, later employing their own cruder versions of bubble shields during the Battle for Earth and Battle of Installation 00. These bubble shields projected a translucent, slightly white/gold tinted protective sphere around the user. The shield itself was similar to a geodesic dome, made of tessellating hexagons. The shield protected against bullets, explosions, lasers, plasma, flames, grenades, and other projectiles. Vehicles and personnel, however, were still able to pass through it. After approximately 20 seconds had passed, the shield would collapse and the generator would self-destruct. After the conclusion of the war, the Office of Naval Intelligence continued to manufacture a small number of similar devices, until 2555, when it refocused its shield research efforts towards Mjolnir-compatible emitters.

During simulations of the Battle of Installation 03 and Battle of New Phoenix a Spartan-IV utilized a version capable of allowing the user to fire weapons at targets while remaining inside the shield. On January 21, 2558, SPARTAN-G059 deployed a bubble shield against Avu Med 'Telcam to block his Type-51 carbine's rounds during her assassination mission. Both UNSC and Banished forces utilized bubble shields with infantry and vehicles during their battle over Installation 00 in April 2559.

Gameplay

Comparison between deployed and undeployed bubble shield.

In the campaign of Halo 3, 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 doors", 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 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.

• An early form of the bubble shield was used in the original teaser trailer for Halo 3. It is shown being used by John-117 to protect him from an incoming 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.
• In the Beta version of Halo 3, the bubble shield looked and rolled like the power drain, did not glow gold, had orange lights, and was able to protect players against the turrets guarding the outer perimeter of the multiplayer map Snowbound.
• If you look closely at the bubble shield, you can see that there are actually two layers of shields that comprise it.
• In Halo Wars, a Shield Protector will deploy a bubble shield-like object onto selected friendly units.
• Although it appears in Halo 3: ODST, it cannot be used by the player or by other allies; only Brutes. This may be because of its extreme weight, weighing in at 20.5 kg. This may also be the reason why Marines are not seen using it in Halo 3 and Halo 3: ODST. In fact, it may never had been intended for personnel-deployment purposes.
• The bubble shield is replaced by the drop shield in Halo: Reach. It is a combination of the bubble shield and the regenerator. The bubble shield is much stronger than the drop shield, which could only take one Wraith shot.
• If one looks closely at the deployed bubble shield, you can see that it "pulses".
• 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.
• Bubble shields do not deflect the automated turrets on Snowbound in the vanilla version of Halo 3 unlike the beta.
• In Halo: Spartan Strike, only Elite Majors are issued with bubble shields, while the player can equip it as default on certain missions.
