The '''power drain''' is a combat support device designed and developed by the [[Covenant]] for its infantry forces. The equipment has several colloquial nicknames among [[United Nations Space Command]] personnel, including "'''Draino'''" and "'''Drainer'''".{{Ref/Reuse|Enc09}}{{Ref/Book|Id=EVG|EVG|Page=47}}


The '''Power Drain''' is a short-range magnetic offensive [[weapon]] featured in ''[[Halo 3]]''.

===Design details===
[[Image:Power Drain in Action.jpg|thumb|left|250px|The Power Drain emits a field of blue energy that strips away all energy shielding in it's range.]]
The power drain is a roughly spherical device massing {{Convert|11.2|lb|kg|disp=flip|sp=us}}. When activated, the device emits a blue [[electromagnetic pulse]] field for around 6.5 seconds, after which the device self-destructs in a small explosion. The EMP is used to short out the electrical systems of any equipment caught within range, including [[energy shielding]] and light vehicles. During its activation, two cylindrical emitters are extruded from the sides of the sphere.{{Ref/Reuse|Enc09}}{{Ref/Site|Id=BNet|URL=http://halo.bungie.net/content.aspx?link=h3betaEquipment|Site=Bungie.net|Page=Halo 3 Beta: Equipment|D=14|M=10|Y=2014}}
The power drain creates a short-range magnetic induction effect which causes disastrous failure of powered field systems within a set radius, and is designed primarily to interfere with common varieties of field-based shielding, [[vehicle]] and power generation. It also has a damaging effect on biological systems and can wound or kill most bipeds in its resulting explosion. <ref>[http://www.bungie.net/content.aspx?link=h3betaEquipment Bungie.net's review of ''Halo 3 Beta'' equipment]</ref> Essentially, the Power Drain is like a reverse [[Regenerator]]; instead of energizing a player's shields, it causes any player's shields within the area of effect to drain away, making them vulnerable to harm. Plus, if you stand near it in the resulting explosion, with stripped shields, you will get killed. The Power Drain can also disable vehicles, rendering them unable to move (or fire weapons) when they drive or fly through it and even about 5 seconds afterwards.  If a Regenerator and Power Drain are deployed in close proximity, the Regenerator will stop working.
 
The Power Drain, like the [[Bubble Shield]], [[Trip Mine]], [[Radar Jammer]] and the [[Portable Gravity Lift]], are all in the category of [[equipment]] and can be deployed using the "X" Button. It activates a very short time after it is thrown - it has just enough inactive time to travel away from the user, leaving them unaffected.
 
The power drain can even disable non drivable vehicles like the [[Scarab]] as seen in [http://uk.media.xbox360.ign.com/media/734/734817/vids_1.html TGS Demo Part 2]. In fact, it will affect any device that runs on any type of energy within its radius in game.
 
==Tactics==
In both Campagin and [[Multiplayer]], this is an effective vehicle-annhilator, provided that you don't stand to near to it when it is active.
 
==Spawns==
'''[[High Ground]]'''
 
The power drain can be found on a small metal ledge inside the main compound of the High Ground base. The ledge is within jumping distance of the flag spot.


'''[[Snowbound]]'''
The power drain has a visual resemblance to the [[flare]] and [[radar jammer]] equipment also developed by the Covenant, save for its blue colouration. The Flare, developed by the [[Jiralhanae]], was based on the same technology as the power drain and radar jammer.{{Ref/Book|Enc22|Page=341}}

The power drain is one of several pieces of deployable [[equipment]] featured in ''[[Halo 3]]''. When thrown, the power drain takes 0.5 seconds to activate, and subsequently lasts 6.5 seconds, equaling a total of [[Seven|7]] seconds. The effects of the power drain pass through walls and floors, so simply fleeing to the bottom floor of a structure after an enemy activates one will still strip one's shields if one passes through the field. This is most noticeable on maps like [[Guardian (Level)|Guardian]].{{Ref/Reuse|H3}}


The power drain spawns near the center man cannon at either side on Valhalla.
The power drain can be used in a glitch called [[Equipment jumping]] by moving against a wall, jumping, and then at highest point of the jump deploying the power drain. This allows a player to jump off of it in mid-air. This is a great tactic for reaching high areas of a map, such as the second level of the tower on [[The Pit]]. This can also be done with the radar jammer and flare. The power drain variation of the glitch is commonly claimed to only be able to be performed as an [[Sangheili|Elite]]. This is not the case, but it is exceedingly difficult to do as a Spartan in the [[Xbox 360]] version of ''[[Halo 3]]''; thus, only a few instances of it have been documented. It appears to be easier to accomplish while playing as a Spartan in the ''Halo 3'' portion of ''[[Halo: The Master Chief Collection]]''.{{Ref/Reuse|H3}}


'''[[The Pit]]'''
In ''[[Halo 3: ODST]]'', the power drain performs as it did in ''Halo 3'' though cannot be used by the player. It is only used by Brute enemies; when the player is in the radius of a power drain, their health will drain in addition to their shields.{{Ref/Reuse|H3ODST}}


The power drain is located in the center of the map, on the bridge connecting the upper level to the control room (between each base).

==Trivia==
*It shares many physical similarities with the [[Radar Jammer]] and [[Flare]], with exception of a blue glow instead of a red/yellow glow.
*It is also capable of draining vehicle power as well, causing the vehicle to stop in its tracks or malfunction. If a vehicle gets in the radius of the drainer for even a brief moment they would lose control of the vehicle. A [[Bungie]] employee remarked that "the guy" he just boarded used the Power Drain to once again disable the [[Banshee]]."
*Although the Power Drainer disables the vehicle's movement, any armaments (etc. [[Scorpion]] Turret, Hog turret)on the vehicle will still work.
*Sometimes throwing the Power Drain at UNSC forces can gradually drain their health over time, resulting in a kill before the explosion.
*In the Multiplayer Beta, the players got the Power Drain and the Bubble Shield mixed up and ended up dying or shielding the enemy player.
*A fun and weird thing to do is throw down a [[Bubble Shield]] and then throw a Power Drain in it and the effect will be contained, like explosions, but the glow will still reach out.
*It may also be used as grenade by throwing it at a group of enemies then it drains their shield,after a while it will explode and sometimes killing the shieldless foes.
*If a player throws a regenerator and a power drain at him self, the regenerator will have no effect and the player's shield will drain as fast as it usually would.
*If a door is blocked by deployable cover a power drain with stop its ability to cover and it's is a good way to allow allied units inside a closed area
*On the Halo 3 campaign, Brutes will occasionally use Power Drains.
*On Valhalla try taking down banshees by tossing one into the Mancannon.
*In the Campaign, it is possible to die from staying within the Power Drain's "field" (It will drain your shields then the explosion will kill you). However, in multiplayer, it cannot kill you, but it will still drain your shields.
*The Power Drain can be thrown through the shield doors on all levels and through a deployed [[Bubble Shield]]. This is a very efficient way to root out campers.

The power drain is a combat support device designed and developed by the Covenant for its infantry forces. The equipment has several colloquial nicknames among United Nations Space Command personnel, including "Draino" and "Drainer".[1][2]

Overview[edit]

Design details[edit]

The power drain is a roughly spherical device massing 5.1 kilograms (11.2 lb). When activated, the device emits a blue electromagnetic pulse field for around 6.5 seconds, after which the device self-destructs in a small explosion. The EMP is used to short out the electrical systems of any equipment caught within range, including energy shielding and light vehicles. During its activation, two cylindrical emitters are extruded from the sides of the sphere.[1][3]

The power drain has a visual resemblance to the flare and radar jammer equipment also developed by the Covenant, save for its blue colouration. The Flare, developed by the Jiralhanae, was based on the same technology as the power drain and radar jammer.[4]

Usage[edit]

The power drain is a piece of infantry support equipment developed by the Covenant, and was heavily employed by the Jiralhanae loyalist forces of the Prophet of Truth during the final weeks of the Human-Covenant War.[2][5][6] Despite their origin, human forces were more than willing to make use of captured enemy power drains during the war.[2]

Gameplay[edit]

Halo 3 and Halo 3: ODST[edit]

The power drain is one of several pieces of deployable equipment featured in Halo 3. When thrown, the power drain takes 0.5 seconds to activate, and subsequently lasts 6.5 seconds, equaling a total of 7 seconds. The effects of the power drain pass through walls and floors, so simply fleeing to the bottom floor of a structure after an enemy activates one will still strip one's shields if one passes through the field. This is most noticeable on maps like Guardian.[5]

The power drain can be used in a glitch called Equipment jumping by moving against a wall, jumping, and then at highest point of the jump deploying the power drain. This allows a player to jump off of it in mid-air. This is a great tactic for reaching high areas of a map, such as the second level of the tower on The Pit. This can also be done with the radar jammer and flare. The power drain variation of the glitch is commonly claimed to only be able to be performed as an Elite. This is not the case, but it is exceedingly difficult to do as a Spartan in the Xbox 360 version of Halo 3; thus, only a few instances of it have been documented. It appears to be easier to accomplish while playing as a Spartan in the Halo 3 portion of Halo: The Master Chief Collection.[5]

In Halo 3: ODST, the power drain performs as it did in Halo 3 though cannot be used by the player. It is only used by Brute enemies; when the player is in the radius of a power drain, their health will drain in addition to their shields.[6]
