Missile Launcher

Missiles have appeared in every single game yet in the Metroid series. It is a more powerful weapon than the normal uncharged Beam, dealing 4-5 times as much damage depending on the game. They are usually first acquired upon finding a Missile Tank, though in Metroid II: Return of Samus and Metroid: Other M, Samus starts off her missions with them, and in Metroid Fusion through an "update" from the Galactic Federation. In most of the Prime games, she loses her Missiles near the beginning but reacquires them later on. Missiles are useful in destroying Brinstone walls and Missile Blocks, and in the Prime games and Other M, can seek targets.

Missile technology is created by many sentient species in different planets across the galaxy. Despite the weapon's various origins, they are all easily compatible with Samus' highly modular Power Suit.

Original Metroid games
The 2D side-scrolling Metroid titles feature rapid-firing missiles. In their usual form, the Missiles have a rocket shape with gray colouring and pink stripes. The Missiles can be fired rapidly, and Samus can hold up to 255, though the total number of them she could acquire varies from game to game.

Super Missiles are a more potent form of missile capable of opening Green Doors and clearing away Cordite. In most 2D Metroid games, Super Missiles have their own separate ammo reserve. However, in the Metroid Prime Series and Metroid Other M, a Super Missile attack draws from ordinary missile reserves, using up five missiles per attack. In Metroid Fusion the Super Missile just makes normal Missiles three times stronger with a more effective propulsion system, and can damage more hardy beings that the standard Missile could not, and simply creates a larger explosion upon impact followed by an aftershock.

Missile Expansions, sometimes called Missile Tanks, can be collected to increase Samus's missile supply by 5 (on Normal difficulty), and 2 (on Hard difficulty) in Metroid: Zero Mission and the Japanese version of Metroid Fusion. In Metroid II: Return of Samus Missile Tanks provide 10 extra Missiles, which in its remake Metroid: Samus Returns was changed to 3 extra Missiles. In Metroid: Other M the expansions only increase Missile capacity by one. In Fusion, it is heavily implied that Missiles are not closely integrated to Samus's body in comparison to her Beam weapons; this is apparent when the cold attributes of the Ice Beam are initially incompatible with Samus's new genetic make-up, while her Missiles, outfitted with subzero properties, seem to have no repercussions against her.

Metroid Prime Series
In the Metroid Prime series, Samus must first obtain the Missile Launcher (which automatically provides a capacity of up to five missiles). She can then further expand her Missile reserves by collecting Missile Expansions; each Missile Expansion increases the maximum missile capacity by five (or ten in Metroid Prime Hunters). There are several uses for missiles in the Prime series, and Missiles can be combined with other weapons for special attacks, though this feature was removed in Metroid Prime 3: Corruption. Missiles in the first two Prime games were blue, and appeared to be energy-based. Corruption differed from the other depictions and seemingly returned to the roots of the franchise by making missiles more similar to the original designs. Missiles of the Prime series always feature a homing ability, although can still miss if the target has quick agility. Some enemies can have a jamming effect on homing missiles, causing them to become erratic and miss their target. A few Space Pirates in Corruption are equipped with specially sloped battle armor that simply deflect missile attacks, making missiles useless against them. However, once their armor is broken, they are vulnerable to missiles. The Missile Troopers and Dark Missile Trooper are also known to use this weapon.

In Metroid Prime Hunters, the missile can be charged to deal more damage. The Missile Launcher is also Samus's Affinity Weapon. When Samus fires a charged missile, it deals more damage and gains a slight homing effect. Other hunter's missiles have no tracking effect. The missile does around 36 damage if uncharged.

In Metroid Prime: Federation Force, Missiles are equippable by Federation Marines. They have seeking properties similar to Samus' Seeker Missile.
 * "An explosive projectile that seeks to its target when fired."

Metroid: Other M
In Metroid: Other M, missiles play a more unique role. Missiles are more often used to damage/eliminate things that other weapons cannot (mostly the Charge Beam). All missile types can only be fired in Search View, however. Metroid: Other M is the first metroid game to introduce a missile supply that can be reloaded and replenished if Samus is low on missiles by holding the Wii Remote vertically, and pressing and holding the A button until her stock is replenished. This technique is known as Concentration, and can also be used to restore energy at dangerously low levels. In Metroid: Other M, the Concentration technique and the Navigation Booths have replaced the Energy Capsules, the Missile Ammo, and the Missile Stations in the previous games as Missile Stations are very rare to find to replenish your missiles.

Methods of acquisition

 * Metroid/Metroid: Zero Mission - Found in a corridor in Brinstar. More specifically, the corridor before the Norfair elevator. In Zero Mission, the Missiles must be collected before the King Worm challenges Samus in the same room.
 * Metroid Prime - Samus has Missiles at the beginning of the game, but they are lost when her suit is damaged by an explosion on the Frigate Orpheon. Reacquired in Hive Totem after the Hive Mecha is defeated.
 * Metroid Prime Hunters - Samus begins the game with the Missile Launcher. It is empty, however, and Missiles are first acquired from a defeated Petrasyl in the Meditation Room of the Celestial Archives.
 * Metroid Prime 2: Echoes - Samus loses the Missile Launcher after being attacked in an alternate dimension whilst on a mission to recover lost Federation troops on planet Aether. She recovers them shortly after locating the Federation's ship, the G.F.S. Tyr, where a Missile Launcher is in storage in a Galactic Federation Ordnance Crate.
 * Metroid Prime 3: Corruption - Samus finds a Munitions Storage containing Missiles on the GFS Olympus.
 * Metroid II: Return of Samus/Metroid: Samus Returns - Samus begins the game with Missiles.
 * Super Metroid - Samus finds the Missiles once again in Brinstar, but in a different room.
 * Metroid: Other M - Samus has the Missiles, and uses one unauthorized to open a door. During the fight with the Brug Mass, Adam gives her permission to use them once again.
 * Metroid Fusion - Samus downloads support data for a Missile Launcher on the Operations Deck.

Super Smash Bros. series
The missile is Samus' side-B attack in Super Smash Bros. Melee and Brawl. It is similar to the 2D appearance and function, but homes in on enemies like in the Prime games. However, unlike all of its appearances in Metroid games, it moves very slowly and will decelerate until it stops and explodes after traveling for a set amount of time. By smashing the joystick before pressing B, Samus will fire a Super Missile rather than a normal one; Super Missiles inflict slightly more damage than normal Missiles but lack a homing ability. When fired, it will initially move even slower than a normal Missile, but rapidly accelerates until it is much faster than a normal Missile. Instead of slowing down at the end of its flight, it travels at full speed until it reaches its maximum range, at which point it will immediately explode.

In Super Smash Bros. for Nintendo 3DS and Wii U, the Missile can be customized. These are its three variants:


 * Missile - "Launch a homing missile. Perform like a smash attack to launch a Super Missile."
 * Relentless Missile - "Launch a slower, more persistent missile. Also, the Super Missile decelerates after a bit."
 * Turbo Missile - "Launch a missile that takes a second to get going. Its direction can be adjusted."

Rocket (Nintendo Land)


Rockets are a Missile-like weapon in Nintendo Land. In Metroid Blast, enemies will fire rockets at the Mii players, which are quite destructive, sending them flying back and costing them a life. One of them is available as a prize. Its description states: "This enemy weapon leaves a trail of black smoke in its wake." This is false.

Types of Missiles

 * Normal Missile- The basic missile Samus gets at the beginning of the game or finds later in the game. Normally does more damage than a regular un-charged Beam shot. Has rapid fire capability in the 2D Metroid games.


 * Super Missile- A stronger version of the missile, sometimes a power-up to regular Missiles or a separate power-up portrayed as a silver projectile with an enlarged green warhead. It appears in Metroid Prime as the Beam Combo for the Power Beam. Metroid: Other M fires the Super Missiles in a similar way to the Beam Combo.


 * Seeker Missile- Yet another missile-based upgrade that only appears in Metroid Prime 2: Echoes, Metroid Prime 3: Corruption and Metroid: Other M. This allows the ability to lock on to up to 5 different targets then simultaneously fire a missile at each (In the case with Other M, one of the five Missiles is actually a Super Missile). In Echoes and Corruption, a single enemy or more may be locked on to multiple times to expose a weakness or to just do more damage.


 * Ice Missile- A Metroid Prime 3: Corruption feature is the Ice Missile upgrade (obtained by defeating Rundas) which turns all normal Missiles into Ice Missiles. Ice Missiles have no negative characteristics or disadvantages over normal missiles and have the added abilities to slow down or freeze enemies, freeze liquids in the environment, and open doors protected by shields vulnerable to cold-based weaponry. It should also be noted that Ice Missiles appear in Metroid Fusion as well, as the Ice Beam was assumed incompatible with Samus' Metroid-infused cellular makeup at the time and therefore could not be downloaded from the Galactic Federation.


 * Homing Missile- Not a true upgrade, but a feature of the Missiles in 3-D games. These seek enemies.


 * Diffusion Missile- Only appearance thus far is during the events of Metroid Fusion. This upgrade adds a charging effect to the Ice Missiles; when fully charged, a successful hit will diffuse it's freezing effect across a large area, chilling anything in the blast radius.


 * Hyper Missile- This is a powerful attack that appears in Metroid Prime 3: Corruption; it uses one standard missile, but can only be used in Hypermode. It puts a large drain on Phazon reserves (equally draining the Hypermode time limit), but creates a very large explosion that can defeat many enemies (and those nearby) in only one hit.


 * Charge Combos- In Metroid Prime and Metroid Prime 2: Echoes, charging a beam and activating a missile will activate a Charge Combo, if that particular beam's Charge Combo has been added to the suit. There have been 7 different types of these (over the course of two games).

Trivia

 * In the Metroid Prime games, Missiles have a slower rate of fire than their variants in the 2-D Metroid games. However, this can be remedied by rapidly pressing and alternating constantly between the buttons that shoot the Missiles and Beams, respectively. This technique is called the Rapid Fire Missiles. An example of this can be seen here.
 * It is revealed in Corruption by use of the X-Ray Visor that the reloading mechanism for the missile launcher is actually operated manually by Samus turning her hand inside the arm cannon, performing the turning motion of the open barrel seen every time Samus fires a missile. However, this action is not performed in Metroid Prime.
 * It should also be noted that there have been a total of four different ways the Arm Cannon morphs when using the missile launcher. In Metroid, the Arm Cannon and the Visor turns a turquoise color (The Varia Suit has the Suit change colors to a reddish-violet as well when Missiles are armed), the second is shown in all games besides Prime and Hunters in which the barrel of the Arm Cannon splits open; it is revealed in Metroid Prime 2 that the arm cannon nozzle rotates when doing this. The third is depicted in Metroid Prime and Metroid Prime: Hunters in which the nozzle splits into four pieces around the barrel in the form of an X. The fourth and final are the formations unique to the arm cannon in Fusion where the two outer pieces separate and the interior piece expands slightly.
 * In Other M, Samus pumps her Arm Cannon after each Missile, similar to a shotgun.


 * In Metroid Prime, firing missiles will not activate any Blue Doors, and instead will bounce off and Samus' visor will display a message saying that it is not a weapon that can open that door. Oddly, this never occurs for the other Blue Doors of the Prime series. This error has been fixed for most, if not all Blue Doors in the Wii versions of Prime.
 * Although Missiles are said to be Samus's Affinity Weapon in Hunters, several enemies seem to have versions of the Missiles and the Missile Launchers in Echoes and Corruption seem to be of Galactic Federation origin.
 * In Metroid: Other M, if Samus fires a Missile at a Desbrachian, there is a possibility that it will bounce off its armor and reflect back at her, dealing light damage.
 * In Metroid Prime Hunters, Samus cannot use Missiles until she obtains a Missile ammo from a defeated Petrasyl. This marks the first game in the series where Missiles cannot be used until a Missile ammo pickup is obtained.
