Find the Dark Beam. Avenge this blasphemy!


The Dark Beam (ダークビーム Dāku Bīmu) is a weapon of Luminoth origin that mimics the dark energy type of Dark Aether and its denizens. This weapon is compatible with Samus Aran's arm cannon, and was integrated into her suit during the events of Metroid Prime 2: Echoes.


Samus acquires the Dark Beam.

The Dark Beam fires strange energy similar to the native energy of Dark Aether. Normal shots resemble swirling flattened disks of this dark energy, trailed by a dark streak and globular emanations. Shots are strong but slow, and quicker enemies can dodge them. Larger concentrations cling to objects, hardening into a brittle shell on contact (see Entangler below). Large quantities of this energy charge and open highly hazardous dimensional rifts (see Darkburst).

Just as with the other Luminoth-designed projectile weapons, the Dark Beam has a limited amount of ammunition. Destroying targets and containers with the Light Beam will give ammunition for the Dark Beam, and vice versa. The Dark Beam's base ammunition capacity is 50, but ammo expansions can be obtained, increasing the maximum ammunition capacity by increments of 50. A maximum ammunition capacity of 250 is possible. If Samus is out of ammo, she can charge the beam to fire an uncharged shot.

The Luminoth originally designed the Dark Beam as a means to combat the Ing Horde, theorising that the energy of the Dark Beam would overload the creatures of Dark Aether, and in effect destroy them. Once tested, this weapon was discovered to be of only average effect against the Ing, causing little damage. With further trial and error, the Light and Annihilator beams were created, which proved to be much more efficient in the battle against the Ing.


Along with activating dark Portals, the Dark Beam has the ability to activate many types of crystalline technology throughout the surfaces of the mirror planets. Firing the Dark Beam at Light-charged crystals can have many effects, ranging from lifting a platform, to moving machinery. The Dark Beam cancels the functioning of Light Crystals and Light Beacons, causing protective umbrellas of light energy to disappear from the surface of Dark Aether. Fortunately, this effect is only temporary, and can be reversed at any time with an application of the Light Beam, or several Power Beam shots. The Dark Beam is also used to open Purple hatches.


Samus uses the Entangler on a Splinter (in Beta Version of Echoes).

A charged mass of dark energy has the strange ability to encase targets, and harden into a brittle shell. The Entangler, the Charge Beam technique for the Dark Beam, exploits this quality. Firing the Entangler will encase multiple targets within a certain radius completely, immobilizing and providing the perfect opportunity to shatter the target with a single Missile, making it quite similar to the Ice Beam from Metroid Prime. This technique is highly effective for use against the troublesome Dark Pirate Commandos, and also effective when used in tandem with the charged Light Beam against Dark Grenchlers.

Samus unleashes the Entangler on a Tallon Metroid.

It is not necessary to directly hit a target with the Entangler, as it will attach to any possible targets within a short radius. Targets hit with the Entangler will become "sticky" for a short time, and cause any other creatures that come into contact with this target to freeze as well, but this will only occur before the dark matter has hardened around the original target. The Entangler seems to possess 'cold' attributes, as it is capable of rendering Metroids extremely fragile to concussive weaponry, a result given by the Ice Beam as well.


Samus uses the Darkburst against two Pirate Commandos.

Once acquired from the Mining Station B, Agon Wastes, Samus can use the Darkburst, the Charge Combo for the Dark Beam. Though it uses up 30 Dark Ammo, as well as 5 missiles, it creates a large sphere from the arm cannon, moving on a fairly fast, straight trajectory.

This particular charged combo is of great use against aerial foes, or large numbers of enemies, ripping apart its molecular structure and drawing it into a "dark dimension, pulling enemies to oblivion."

Metroid Prime 2: Echoes manual[]

"The Dark Beam can hinder enemies, extinguish Light Crystals, and is effective against Light Aether enemies. Charge it to fire the Entangler, which enshrouds enemies in shadow. The Dark Beam can open purple hatches."

Samus's Notes

When out of Dark Ammo, you can charge the Dark Beam to fire a normal shot.
Fire the Dark Beam to deactivate Crystals.
Dark Beam blasts have limited effect on Ing and dark creatures.
It takes several hits with the Dark Beam to hinder enemies and enshroud objects with dark matter.
Charge the Dark Beam to fire an Entangler blast. Enemies struck by this blast will be enveloped in shadow tendrils for a few moments, unable to move or fire.
The Entangler costs 5 Dark Ammo to fire.

Behind the scenes[]

The "dark energy" fired by this weapon is known to current terrestrial science, if only hypothetically: cosmologists believe that this "negative gravity" permeates the vacuum of space and repels all matter, driving the expansion of the universe. If significant amounts of the field could somehow by concentrated and fired, the massive yet localized expansive force would likely be quite damaging, tearing the target apart from within.


  • There are multiple similarities between the Dark Beam and the Ice Beam. One being that the Dark Beam uses the same "raised" shape Arm Cannon configuration. Secondly, both beams can immobilize targets. Additionally, their Charge Combos function similarly. Even still, the Dark Beam has several advantages, such as a higher rate of fire, and an overall higher capability to cause damage, seeing as how there are more enemies weak to it in comparison.
    • Additionally the Dark Beam shares the Ice Beam usefulness against Metroids even Dark Tallon Metroids.
  • The Dark Beam was given its name by the Space Pirate Science Team, although I-Sha refers to it by the same name.
    • Despite the fact that the weapon was in Space Pirate hands when Samus found it, I-Sha told her that it had been claimed by the Ing. This would appear to apply to the Light Beam instead, as it was found on Dark Aether.
  • This weapon is one of two pieces of Luminoth technology to make use of dark energy, the other being the Dark Sentinel Crystal.
  • Dark Samus is vulnerable to the Dark Beam rather than the Light Beam because she is a being of the Light world. She is often confused with Darklings, when she is a separate copy of Samus.
    • Additionally, the Dark Beam is found on Light Aether, while its Light counterpart is found in the dark world of Aether. The rooms where the Beams are found are also polar opposites of each other.
  • Out of the three beams introduced in Metroid Prime 2: Echoes, the Dark Beam's icon is the only one with the least amount of changes from its early beta icon, retaining its general shape while the other two beam icons received large-scale redesigns.
  • The Entangler was designed by Andy O'Neil. According to Kynan Pearson, it was originally much more powerful, generating twice as many globules of darkness on impact, which had a larger area of effect that could spread and hit multiple targets.[1]
