Changes: Electromagnetic pulse

Revision as of 13:42, 7 December 2017

There is more information available on this subject at Electromagnetic pulse on the English Wikipedia.

Snap28 — The EMP medal awarded to a player in Halo 3 and Halo 3: ODST after killing an enemy shortly after its shields were depleted by an EMP.

An electromagnetic pulse (EMP) is the electromagnetic radiation from an explosion (especially a nuclear explosion) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium. The resulting electric and magnetic fields may couple with electrical systems to produce damaging current and voltage surges. The effects are usually not noticeable beyond the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic shockwave. An alternate definition is: a broadband, high-intensity, short-duration burst of electromagnetic energy.

Featured

EMP is mentioned several times in the Halo universe:

In the level Two Betrayals in Halo: Combat Evolved, Cortana converts John-117's energy shields into an EMP to disable Halo's Phase Pulse Generators.
The detonation of Shiva-class Nuclear Missiles are followed by a massive electromagnetic pulse.
The Deep-Space Artifact released an enormous electromagnetic pulse that briefly disabled all communications in the Sol system.
In Halo: First Strike, John-117 used a Plasma Grenade's EMP charge to disable the electronics of a locked door on Ascendant Justice. This allowed him to open the door.
The in-atmosphere jumping of the Prophet of Regret's assault carrier to slipspace above New Mombasa created a massive electromagnetic pulse that damaged electrical systems in the city.

Gameplay

A charged Plasma Pistol blast will completely deplete energy shields.
In all Halo games except Halo: Combat Evolved and Halo 2, a charged Plasma Pistol blast will temporarily disable vehicles.
In Halo 3, the Power Drain uses EMP to disable shields, vehicles and other power sources.
In Halo Wars, Professor Anders' vehicle, the Gremlin, uses EMP as main armament to disable enemy non-infantry units.
In Halo Wars, the Vampire's Stasis Drain Cannon uses EMP to drain power from enemy aircraft.
In Halo: Reach, the M319 Individual Grenade Launcher's grenades release an EMP when detonated.
In Halo: Reach, an EMP is released when the player comes out of Armor Lock.
In Halo: Reach, the Covenant Spires in the Battle of Viery possessed a protective electromagnetic shield to disable enemy vehicles.

-The worst of an electromagnetic pulse generally only lasts for a second, but any unprotected electrical equipment will be affected by the pulse.
+EMP is mentioned several times in the [[Halo Universe|''Halo'' universe]]:
+*In the level [[Two Betrayals]] in ''[[Halo: Combat Evolved]]'', [[Cortana]] converts [[John-117]]'s [[energy shielding|energy shields]] into an EMP to disable [[Installation 04|Halo]]'s [[Phase Pulse Generator]]s.
-==Appearances==
+*The detonation of [[Shiva-class Nuclear Missile]]s are followed by a massive electromagnetic pulse.
-EMP is mentioned several times in the [[Halo Universe]]:
+*The [[Deep-Space Artifact]] released an enormous electromagnetic pulse that briefly disabled all communications in the [[Sol system]].
+*In ''[[Halo: First Strike]]'', John-117 used a [[Type-1 Antipersonnel grenade|Plasma Grenade]]'s EMP charge to disable the electronics of a locked door on ''[[Ascendant Justice]]''. This allowed him to open the door.
-*In the level [[Two Betrayals]] in ''[[Halo: Combat Evolved]]'', [[Cortana]] diverts John's [[energy shielding|energy shields]] into an EMP to disable [[Installation 04|Halo's]] [[Phase Pulse Generator]]s.
-*The detonation of [[Shiva-class Nuclear Missile|Shiva-class Nuclear Warheads]] are almost always followed by a massive electromagnetic pulse.
+*The in-atmosphere jumping of the [[Prophet of Regret]]'s [[Solemn Penance|assault carrier]] to [[Slipstream Space|slipspace]] above [[New Mombasa]] created a massive electromagnetic pulse that damaged electrical systems in the city.
-*The [[Deep-Space Artifact]] let out an enormous electromagnetic pulse that briefly canceled out all communications in the [[Sol System]]. It later let out another pulse upon deactivation.
-*In ''[[Halo: First Strike]]'', [[John-117]] used a [[Type-1 Antipersonnel grenade|Plasma Grenade]]'s EMP charge to disable the electronics of a locked door on ''[[Ascendant Justice]]''. This allowed him to open the door.
-*The in-atmosphere jumping of the [[Prophet of Regret]]'s [[Solemn Penance|Assault Carrier]] to [[Slipstream Space|Slipspace]] above [[New Mombasa]] creates a massive electromagnetic pulse that damaged electrical systems in the city, and fried the navigational and safety systems of nearly five dozen [[Single Occupant Exoatmospheric Insertion Vehicle|SOEIV]] pods unfortunate enough to drop into the city at that exact moment, plunging them and the [[Orbital Drop Shock Trooper]]s inside free-falling to certain death.
 ===Gameplay===
+*A charged [[Type-25 Directed Energy Pistol|Plasma Pistol]] blast will completely deplete energy shields.
-EMP is also an in-game effect in the ''Halo'' games, that disables energy shields and vehicles. It is produced by certain weapons and equipment.
+*In all ''[[Halo Franchise|Halo]]'' games except ''Halo: Combat Evolved'' and ''[[Halo 2]]'', a charged Plasma Pistol blast will temporarily disable vehicles.
-*In ''[[Halo 2]]'', the [[Sentinel]]s sometimes emit an EMP when destroyed. This effect disables shields, but vehicles are unaffected.
 *In ''Halo 3'', the [[Power Drain]] uses EMP to disable shields, vehicles and other power sources.
+*In ''[[Halo Wars]]'', [[Ellen Anders|Professor Anders]]' vehicle, the [[XRP12 Combat Support Vehicle|Gremlin]], uses EMP as main armament to disable enemy non-infantry units.
-*A charged [[Type-25 Directed Energy Pistol|Plasma Pistol]] blast will temporarily disable vehicles and energy shields much like the power drain.
+*In ''Halo Wars'', the [[Type-29 Close Support Fighter|Vampire]]'s [[Stasis cannon|Stasis Drain Cannon]] uses EMP to drain power from enemy aircraft.
-*In ''Halo: Reach'' the [[M319 Individual Grenade Launcher]] has a secondary function that acts like an EMP. It awards a player an EMP Medal when it kills an enemy, being the only other weapon in the game that awards the medal.
+*In ''[[Halo: Reach]]'', the [[M319 Individual Grenade Launcher]]'s grenades release an EMP when detonated.
-*In ''Halo: Reach'', [[Armor Abilities#Armor_Lock|Armor Lock]] can trigger an EMP after use, which can take out a Spartan's shields. Combined with a quick and accurate melee, this can result in an almost instant kill.
+*In ''Halo: Reach'', an EMP is released when the player comes out of [[Armor Ability#Armor Lock|Armor Lock]].
-*In ''Halo Wars'', [[Ellen Anders|Professor Anders]]' vehicle, the [[Gremlin Combat Support Vehicle|Gremlin]], uses EMP as main armament to disable enemy non-infantry units.
-*In ''Halo Wars'', the [[Type-29 Close Support Fighter|Vampire]]'s [[Stasis cannon|Stasis Drain Cannon]] uses EMP as well to drain power from enemy aircraft.
 *In ''Halo: Reach'', the [[Covenant Spire]]s in the [[Battle of Viery]] possessed a protective electromagnetic shield to disable enemy vehicles.
-==Trivia==
-*If you disable a vehicle using an EMP, it will show an animation of some sparks flying around but if you disable it again before it is drivable then the animation will stop and the vehicle will not work.
-*A vehicle disabled by an EMP will still have full functionality of its weapons if it has any. For example, if a [[M12 Force Application Vehicle|Warthog]] is disabled by an EMP, the turret will still be able to turn around and shoot.
-*The Shade is not affected by the EMP of the Plasma Pistol, as it can still rotate and shoot.
-**This has been fixed in Halo: Reach
