Charge Combos, also known as Beam Combos, are special weapons featured in the first two games of the Prime Trilogy, Metroid Prime and Metroid Prime 2: Echoes. A Charge Combo is used by fully charging a beam weapon, and then combining it with a secondary weapon. This will "combine" its energy with the energy from the beam, and fire the Charge Combo.

The Special Charge Beam Attacks in Super Metroid were very similar, and acted as a precursor.

Metroid Prime SeriesEdit

Metroid Prime and Metroid Prime 2: Echoes contain four beam weapons, and consequently, four Charge Combos. They are items like any other, which must be acquired before they can be used. With the exception of the Super Missile, all Charge Combos are entirely optional items, serving only to aid Samus in combat.

There are two types of Charge Combos: Single Charge Combos and Continuous Charge Combos. Single Charge Combos fire one blast at a time and usually deplete 5 or 10 missiles (in the case of the Darkburst, Sunburst, and Sonic Boom only use 5 missiles, but also use 30 of the respective beam). Continuous Charge Combos fire a constant stream which can be stopped by Samus at will, by releasing the "Y" button or down on the D-pad, depending on the game version. Continuous Charge Combos require 10 missiles to activate, and deplete 5 missiles per second afterward. (Flamethrower and Wavebuster)

Super MissileEdit

Main article: Super Missile
The Super Missile is the Charge Combo of the Power Beam, and is a Single Charge Combo. Since both Prime and Echoes include the Power Beam, both games also include the Super Missile. The Super Missile is special, as it is the oldest of the Charge Combos, being a feature of the Metroid series since Super Metroid. It is also, in the Prime games, a required item.

WavebusterEdit

Main article: Wavebuster
The Wavebuster is the Charge Combo of the Wave Beam, and is a Continuous Charge Combo. The Wavebuster is found in Metroid Prime, in the Chozo Ruins area. It fires a stream of violet electricity, paralyzing enemies. It resembles the Grapple Voltage of Corruption.

Ice SpreaderEdit

Main article: Ice Spreader
The Ice Spreader is the Charge Combo of the Ice Beam, and is a Single Charge Combo. Found in the Magmoor Caverns area of Metroid Prime, the Ice Spreader will coat whatever it touches in a thick layer of ice, and can be used to freeze multiple targets.

FlamethrowerEdit

Main article: Flamethrower
The Flamethrower is the Charge Combo of the Plasma Beam, and is a Continuous Charge Combo. It is found on the first level of Phazon Mines in the original Metroid Prime, and when fired will release a very short-ranged stream of fire, dealing immense damage to all it touches. The Flamethrower is useful against large groups of nearby enemies, as it can be swept quickly over them, burning them to ashes.

DarkburstEdit

Main article: Darkburst
The Darkburst is found in Metroid Prime 2: Echoes, the Charge Combo of the Dark Beam. It is a Single Charge Combo, as are all the Charge Combos in Echoes. The Darkburst is a very slow-moving projectile, but on impact will create a black hole, sucking in all nearby enemies to a "dark dimension" unrelated to Dark Aether. The Darkburst needs 5 missiles and 30 dark beam ammo in order to be fired.

SunburstEdit

Main article: Sunburst
Again found only in Echoes, and again a Single Charge Combo the Sunburst is the Charge Combo of the Light Beam. Like its complement the Darkburst, this weapon fires a large, slow moving projectile: a sphere of intensely bright, rainbow-tinted light. It will deal immense damage to creatures from Dark Aether. The Sunburst requires 5 missiles and 30 light beam ammo to fire. If the cluster is close to a target it will fire rays of intense heat at an opponent that is within in reach.

Sonic BoomEdit

Main article: Sonic Boom
The Sonic Boom, the Charge Combo of the Annihilator Beam, is the final Charge Combo of Metroid Prime 2: Echoes. This weapon, unlike the Darkburst and Sunburst, fires an extremely fast projectile, so fast; in fact, that it will instantly appear next to the target. The Sonic Boom tears a rift in space, severely damaging any nearby enemies. This Charge Combo puts the heaviest drain on Samus' resources, consuming 5 missiles, 30 light beam ammo, and 30 dark beam ammo in one blast.
