The '''energy projector''', also known as the '''cleansing beam''',<ref>'''Halo Wars'''</ref><ref name="EVG">'''[[Halo: The Essential Visual Guide]]''', ''page ???''</ref> or '''ventral beam''' due to its most common placement on warships,<ref>'''Halo: Mortal Dictata'''</ref> is a [[Covenant]] weapon used exclusively by large [[capital ship]]s. It fires a thin beam of energized matter, capable of destroying ships effortlessly at long range and "[[glassing]]" planets, systematically rendering them sterile and incapable of sustaining life.

==History==
The energy projector was first encountered by the [[UNSC]] during the [[Second Battle of Harvest]], where it was used by a [[Covenant super-destroyer]]. It was more frequently seen in later years, such as during the [[Harvest]] [[Harvest Campaign|campaign]] and [[Operation: TORPEDO]]. Throughout the course of the [[Fall of Reach|Covenant invasion of Reach]], the population centers suffered tremendous structural damage due to the Covenant's glassing of the planet.<ref>'''[[Halo: Reach]]''', campaign level ''[[New Alexandria (level)|New Alexandria]]''</ref> Similarly, several frigates fell prey to the energy projectors during the engagement.<ref>'''Halo: Reach''', campaign level ''[[Tip of the Spear]]''</ref>

In a bid to kill [[John-117]], the ''[[Solemn Penance]]'' used an energy projector to destroy the [[Prophet of Regret]]'s temple after his assassination by the Spartan on [[Installation 05]].<ref>'''Halo 2''', campaign level ''[[Regret (level)|Regret]]''</ref> In the [[Battle of Earth]], the city of [[Voi]] was glassed by the [[Fleet of Retribution]] to stop a [[Flood]] infestation.<ref>'''Halo 3''', campaign level ''[[Floodgate]]''</ref> According to Lord Hood, half of the African continent was glassed shortly after, though it was almost certainly an exaggeration given the lack of damage when Voi is later seen<ref>'''Halo 3''', campaign level ''[[Halo (Halo 3 level)|Halo]]''</ref> and his distaste for the Sangheili.

===Operation===
The weapon fires a thin beam of highly energetic particles, or plasma. It typically requires a brief charging period, during which a visible maelstrom of plasma appears around the emitter. The beam has an effective range of over 100,000 kilometers. The beam varies in color, possibly according to power output, but it generally appears as a silver-white color,  similar to the scintillation effect that is seen when a Covenant ship's energy shields are hit. Beams in the red, purple, orange and blue spectra have also been observed.

The energy projector's long range allows a ship armed with such weapons to 'snipe' targets during ship-to-ship combat. The weapon has been observed to gut UNSC ships from stem to stern, as happened to the [[UNSC frigate|frigate]] {{UNSCShip|Gettysburg}} over Reach.<ref name="for"/>

===Effects===
[[File:H2A Cutscene EnergyProjectorPiercing.png|thumb|300px|A {{Class|CAS|assault carrier}}'s energy projector piercing the hull of a {{Class|Marathon|heavy cruiser}}.]]
Against UNSC vessels, the weapon is able to pierce dozens of centimeters of [[Titanium-A armor]] with comparative ease, rendering any form of physical defense useless. A single hit can potentially disable or destroy vital systems, such as the [[Magnetic Accelerator Cannon]] or engines, as seen during the [[Battle of Earth]] when a single pulse from an [[Covenant assault carrier|assault carrier's]] dorsal energy projector crippled a {{Class|Marathon|heavy cruiser}}. If an energy projector strikes in a critical area, such as the reactors of a ship, it could destroy the ship instantly.

The beam is functionally similar to the infantry-issued [[Type-50 particle beam rifle]], albeit on a vastly larger scale. It is also speculated that the beam can be focused to varying degrees. In space, the beam can be focused to a smaller, more concentrated, and thus more powerful beam generally used to decimate enemy fleets from afar. It also seems to drain all or most of the energy in a Covenant ship for a brief period, unless the ship is big enough to supply the power without too much of a drain.

When used for "glassing" a planet, the energy projector causes near-total atmospheric and biospheric destruction. The beam vitrifies the soil, converting massive swaths of terrain into molten glass, and causes massive atmospheric disruption. The climate of the planet is drastically altered, sometimes permanently; Harvest's global temperature dropped after being glassed, sending the planet into an "ice age." 

An energy projector beam also generates massive electromagnetic disturbances; energy shield systems are known to fail when within several miles of an active beam.

===Distribution===
According to [[Frederic-104]], "Only the big ships have them". {{Class|ORS|heavy cruiser}}s, [[Covenant supercruiser|supercruisers]], [[Covenant assault carrier|assault carriers]], {{Class|CSO|supercarrier}}s, {{Class|CPV|heavy destroyer}}s and {{Class|CCS|battlecruiser}}s are known to be equipped with energy projectors. Assault carriers are armed with one energy projector underneath the bow, one on their dorsal sides, and one near the [[gravity lift]]. ''CCS''-class battlecruisers feature one under the bow and one on the underside of the gravity lift platform.

Covenant {{Class|CRS|light cruiser}}s carry their own ventral beam weapons - most likely smaller, less powerful versions of the energy projectors used by their larger cousins. This weapon charges up like an energy projector, but glows green. In [[2557]], a Covenant light cruiser orbiting [[Requiem]] attempted to destroy the {{UNSCShip|Forward Unto Dawn}} using its ventral energy weapon, but was stopped when John-117 destroyed the cruiser with a [[M4093 Hyperion nuclear delivery system|Hyperion-class nuclear missile]].

Some classes of Covenant [[space station]]s also carry energy projects as their main defensive capability; one of the few known instances of this was when the {{UNSCShip|Infinity}} encountered a [[Oth Lodon station|Covenant battlestation]] orbiting the gas giant [[Oth Lodon]] in [[2558]]. In this engagement the station, commandeered by [[Insurrectionist]]s of the [[New Colonial Alliance]] fired the station's main energy projector upon the UNSC flagship, severely damaging it with a single shot. This particular projector was mounted upon the station's central "tower", allowing for maximum range and effect against approaching targets.<ref name="HE5">'''[[Halo: Escalation]]''' — ''[[Halo: Escalation Issue 5|Issue #5]]''</ref>

==''Halo Wars''==
In ''[[Halo Wars]]'', the [[Prophet of Regret]] uses the '''Cleansing Beam''' as his leader power. An orbiting vessel "[[Glassing|glasses]]" the target, and has the power to destroy almost anything. The weapon's capabilities can be upgraded to progressively increase power and decrease supply usage at the [[Covenant temple|temple]]. The upgrades are named ''Regret's Sentence'', ''Regret's Doom'', and ''Regret's Condemnation'', respectively.

To use it, the player must select the Prophet of Regret and press the '''Y''' button. The player can then use the left thumbstick to move the beam around the Prophet's field of view. The Cleansing Beam can damage all units, including the player's and allies' forces; however, Regret himself cannot be damaged by the beam. The beam's color is dependent upon the player's team color.

==Trivia==
*The color of the energy projector's beam is not the same in every game. In ''[[Halo 2]]'', it is purple. In ''[[Halo 3]]'', ''[[Halo 3: ODST]]'' and ''[[Halo 2 Anniversary]]'', it is blue. In ''[[Halo: Reach]]'', it is red, In ''[[Halo Wars]]'' it changes depending on what the team color is. This may be indicative of different power settings, as the energy projectors of [[CCS-class battlecruiser]]s have been seen in all three colors.
*The time an energy projector takes to charge also varies. The ''CCS''-class battlecruiser fought at the end of ''Halo: Reach'' takes 20 seconds to charge its energy projector, while ships of the same class in [[New Alexandria]] are shown charging theirs in only two, then sustaining fire for [[seven]] seconds. Likewise, a ''CAS''-class assault carrier in ''ODST'' is shown charging its projector in thirty-six seconds, but an earlier one charges its own indefinitely until the player passes through a gate. This could be explained by a difference in operation, such as the cruisers at New Alexandria needing to expend less energy to destroy some buildings at New Alexandria while needing more to cut through the heavily armored ''{{UNSCShip|Pillar of Autumn}}''.
