The '''Assassination''' is a gameplay feature  that allows player to enter a third-person view while elaborately taking an enemy player down with a close combat weapon, usually a [[Combat knife|Combat Knife]], [[Energy dagger]], [[Type-1 energy sword|Energy Sword]], [[Type-2 gravity hammer|Gravity Hammer]], or a Ball/Bomb or their hands, knees, legs and feet. Note that assassinations are different from beat downs and pummels. Pummels are kills from a normal melee attack; a beat down occurs when Player A melees Player B by simply tapping the melee button while behind them, resulting in an instant kill. An assassination occurs when Player A presses and holds the melee button when directly behind Player B, resulting in an elaborate kill that earns the player a special medal.  Assassinations have been featured in ''[[Halo: Reach]]'', ''[[Halo 4]]'', and ''[[Halo 5: Guardians]]''. Assassinations performed in ''Halo: Reach'' [[multiplayer]] matchmaking also count towards the [[List of Halo: Reach commendations#Rear Admiral|Rear Admiral]] commendation; those performed in ''Halo 4'' matchmaking and [[Spartan Ops]] advance the [[List of Halo 4 commendations#Assassin|Assassin]] and [[List of Halo 4 commendations#Backstab|Backstab]] commendations respectively.

== Mechanics ==
There are four different basic assassination types that are played according to the species of the players and the current situation: If both players are on the ground, if the assassin is in the air and the victim is on the ground, if both players are in the air, and if the assassin and the victim are both on the ground, but the assassin is higher in elevation than the victim.<ref>[http://halo.bungie.net/Forums/posts.aspx?postID=54675449&viewreplies=true&postRepeater1-p=1 '''Bungie, Reach Forum''' - ''The Assassination Index Thread: ALL Assassinations With VIDEOS'']</ref>

The specific assassination animation that is used when both players are on the ground is dependent of where the initial melee lands on the victim's body.

There are also unique assassinations that can be performed when the player is holding an Energy Sword, Gravity Hammer, or Ball/Bomb.

[[File:SpartanAssassination.jpg|thumb|A Spartan assassinating another Spartan.]]
When playing as a [[SPARTAN-III program|Spartan]] in ''Halo: Reach'' matchmaking, you can perform several different assassinations using your combat knife that is located on different parts of your armor, depending on what chest piece you are wearing.

; Both players are on the ground
This assassination involves Player A standing on the same surface as Player B. The specific animation that is used varies depending on which part of the back is meleed.

* The initial melee hits the right shoulder of player B: Player B is spun around to face player A. Holding the knife with the blade pointed up in his/her clenched fist, player A "punches" player B in the chest, stabbing him or her.
* The initial melee hits the right side of player B's back: Player B turns to face player A, who raises his/her combat knife and plunges it down on player B's head.
* The initial melee hits the center of player B's back: Holding the knife with the blade pointed down in his/her fist, player A forcefully stabs player B in the back, and player B is dragged to the side when the knife is removed. 
* The initial melee hits the left side of player B's back: Player A spins the knife, stab's player B in the back, then tosses the body off to the side.

; Player A is more elevated than player B, but both are on a surface
Player A extends their arm around player B's neck, bending their stomach outward, then stabbing him/her in the gut. 

; Both players are airborne
This assassination involves Player A jumping (or possibly falling) right behind (Close enough proximity to melee) Player B. Player A will initiate the assassination, which involves player A wrapping his/her hands together, and delivers a smash on player B's head. 

Note: if the assassin is wielding an Energy Sword, the animation will be bugged, which results in a armor morphing glitch, where both players armor permutations will become one.

; The assassin is airborne, but the victim is not
Player B is knocked to the ground, face down. Player A steps on his/her back, crouches down, and snaps their neck.

===Spartan vs. Elite===
[[File:EliteAssassination.jpg|thumb|A Spartan assassinating an Elite.]]
; Both players are on the ground

== ''Halo 4'' ==
{{expand-section}}
Assassinations returned to the ''Halo'' series in ''Halo 4''. Assassinations in ''Halo 4'' seem to be based on the angle at which the initial melee is performed rather than hitting a specific portion of the victim's back, as in Halo: Reach. A new medal, [[Airsassination]], is awarded for midair assassinations. Players can now perform assassinations with Flags in [[Capture the Flag]] (rewarding [[Flagsassination]] medal) and with the [[Skull]] in [[Oddball]] and [[Grifball]] (rewarding [[Ballsassination]] medal).<ref>[http://www.youtube.com/watch?v=35_pXjNsDUY '''YouTube''' - ''Halo 4 Flag Stabbing and Spartan Cosplay - Comic-Con 2012'']</ref> All forms of [[Prometheans]] can also be assassinated in [[campaign]] and [[Spartan Ops]].<ref>[https://www.youtube.com/watch?v=gWpXszjy3io&feature=g-all-u '''YouTube''' - ''Halo 4 - Campaign Impressions'']</ref> However, a [[Promethean Watcher]] will continue reviving a fallen Promethean or projecting its [[Z-90 hardlight shield|Hardlight Shield]] onto a nearby enemy while being assassinated.

== ''Halo 5: Guardians'' ==
In ''Halo 5: Guardians'', assassinations are introduced into Spartan customization, allowing players to choose from a number of different animations. The various new animations are unlocked via the [[Requisition system]]. Assassinations otherwise remain the same as in ''Halo 4'', although [[Promethean Watcher]]s are now immune to being assassinated. In addition, the [[Promethean Soldier]] and [[Warden Eternal]] can be assassinated. The [[Halo 5: Guardians skulls#Black Eye|Black Eye]] skull has also been altered so that it recharges the player's [[energy shielding|energy shields]] after the assassination has been performed as opposed to recharging them during the assassination.

== Beat Downs vs. Assassinations ==
With normal beat downs, one will quickly melee the opponent's back, resulting in an instant kill, but will stay in first person view. This earns them a medal but no credit or commendation increase. With an assassination, the player goes into third person view and performs a special finishing move. In campaign, assassinations are not silent and will alert nearby enemies. During an assassination, the player runs a risk of getting their kill stolen by a teammate, which results in the teammate getting a [[Yoink]] medal in Halo: Reach. The player is also able to be damaged and even killed during the animation, which will cause the victim to be saved and the savior will get a [[Showstopper]] medal. This makes assassinations relatively unpopular for fast-paced gametypes such as [[Oddball]] or [[Team SWAT]]. Also, performing assassinations will negate fall damage, unlike beat downs. This allows players to survive fatal falls if an enemy happens to be directly below. This is featured in the achievement [[If They Came to Hear Me Beg]].

== Trivia ==
* Because assassinations are naturally a one-hit kill, any of them performed with an Energy Sword do not deplete the sword's charge, nor do they count toward the weapon spree medals [[Sword Spree]], [[Slice 'N Dice]] or [[Cutting Crew]]. Also, if the assassin is holding a depleted Energy Sword, assassinations will still animate with the deactivated sword, that is, the enemy will be impaled by an invisible blade.
*Early in the ''[[Halo: Reach Multiplayer Beta]]'', players could assassinate their teammates with full assassination animations, resulting in a betrayal.
* There was an assassination in the ''Halo: Reach Multiplayer Beta'' where an airborne Elite would stab a groundside Elite through the head with an energy dagger, then pull it out with some resistance. This animation was removed in the final game.
* The Elite-vs-Spartan assassination triggered by hitting the Spartan's right shoulder, if performed along a ledge, has become known among the community as the "Sparta Kick" assassination, as it resembles a scene from the film ''[[Wikipedia:300 (film)|300]]'' where the Spartan Leonidas kills a Persian messenger by kicking him down a well. Ironically, this assassination involves the Spartan being killed instead of doing the killing.
* The Grunt assassination involving breaking the Grunt's neck has also become known on Bungie.net as the "Grunt Buddy" assassination, as it is commonly freeze-framed to make it look as if the Spartan is giving the Grunt a one-armed hug while giving a thumbs up with his other hand.
* Even though the player is killing an enemy during an assassination, AI allies will still regard the enemies as alive, and will continue to fire at the enemy being assassinated, which may result in the player having their kill stolen, losing health, or even dying from friendly fire.
* [[Yanme'e|Drones]], [[Mgalekgolo|Hunters]], [[Huragok|Engineers]], [[Promethean Watcher]]s (the latter only in ''[[Halo 5: Guardians]]''), and {{Pattern|Pnap|Goblin}}s cannot be assassinated.
* Some assassinations require a certain amount of space to perform. If there is not enough space, a different animation than usual will occur, or the animation will be cut short.
*If an Elite wearing a closed helmet is involved in an Assassination, either killing or being killed, its jaws may clip through its helmet.
* Occasionally if an online game suffers lag, a player who was assassinated may be revived and continue to fight. Their health may or may not be low. Sometimes the assassin will continue performing the assassination on thin air and the victim will appear to escape, only to die when the assassination is completed.   
* If an assassination is performed on a slope, the two characters involved may end up performing the same animations while standing at the wrong distance from each other. This may cause the assassination to look disconnected, and occasionally cause the knife being used to be stabbed in the wrong place rather than where it was intended. However, this does not affect the outcome, and the attacked character will still die.
* Some assassinations have enough range to kill a second enemy who stands too close to the attacker.
* Elites may sometimes laugh after performing an assassination.
* Performing assassinations by unaware or sleeping enemies may sometimes alert them to the player's presence, if they hear the victim's yells. The only one known that doesn't is the Spartan-vs-Elite assassination that is triggered by attacking from midair, since it involves crushing the Elite's head, thus preventing him from yelling.
* There are [[Seven|7]] assassinations for each type of scenario, excluding in Campaign and using Energy Sword or [[Type-2 gravity hammer|Gravity Hammer]].
* The Grunt assassinations seem to be inspired by [[Cal-141]]'s ways of killing Grunt sentries in [[The Babysitter]].
* A cut animation for ''Halo: Reach'' allowed Sangheili to assassinate Marines and Army troopers. The animation depicted them being grabbed by the head and having their neck snapped.<ref>[https://twitter.com/game_fabricator/status/695983088321503232 '''Twitter.com''', ''Marcus Lehto: "Oh yeah, that was a good one. Intended to reinforce just how powerful the Elites were."'']</ref>
* An Assassination that appears in ''Halo 5: Guardians'' titled ''"104 Ways to Die"'' may be a possible nod to Fred-104, a SPARTAN-II known for his proficiency with knives.
* In the ''Halo 5: Guardians'' campaign, any character who does an assassination will randomly say one of two quotes. The quotes vary for each character, although [[Jameson Locke]] has only one line when he assassinates an enemy: "He's dead. Who's next?", which he says slightly differently each time.
* For each assassination, there is a point during it when the victim receives the killing blow, indicated by their shields breaking or (if their shields are already broken) the victim's HUD's health bar decreasing to zero. Before this point, killing the assassin will save the victim and they will survive without injuries (even if the assassination in question featured them getting injured before the killing blow). After this point, killing the assassin will still leave the victim dead.
