Editing Alert carry

{{Merge from|Lowering weapon glitch}}
{{Status|RealWorld}}
The '''alert carry''', sometimes mistakenly called '''"ceasing fire"''', '''"standing down"''', or '''"gun down"''', is a feature introduced in ''[[Halo 2]]'' for machinima purposes, and has since appeared in ''[[Halo 3]]'', ''[[Halo 3: ODST]]'', ''[[Halo: Reach]]'', ''[[Halo 4]]'', ''[[Halo 2: Anniversary]]'', ''[[Halo 5: Guardians]]'', ''[[Halo Infinite]]'' and ''[[Halo: Campaign Evolved]]''. The feature allows gamers to holster or lower their in-game weapons; it is commonly used when making [[machinima]]. The exact execution of the alert carry has changed between games and requires different button combinations for different game [[Halo Xbox controls|controller layouts]].

== ''Halo: Combat Evolved'' ==
[[File:HTMCC-HCE AlertCarry SplitScreen Example Screenshot.png|thumb|400px|A player has to keep looking down while he's performing an alert carry.]]
The alert carry can be performed in ''Halo: Combat Evolved'' by simply looking down. Although the player is looking at the ground, others will see their head looking forward with their arms and weapons pointed at the ground. Generally, using a [[CE:Pistol|Pistol]] or a [[CE:Plasma Pistol|Plasma Pistol]] resulted in a more relaxed effect; using a [[CE:Needler|Needler]] or an [[CE:Assault Rifle|Assault Rifle]] tended to bend the left arm inwards.

== ''Halo 2'' ==

Noticing that ''[[Red vs Blue]]'', which frequently used the alert carry effect, helped the ''Halo'' franchise, [[Bungie]] made it easier to perform the technique in ''Halo 2'' by assigning it its own input action system.

The alert carry is shown by looking down at the player's legs, they will not be as bent as normal. Other players will see it as your weapon being lowered. Shooting, throwing grenades, [[H2:Melee|meleeing]], reloading, entering vehicles, dying, or pressing the '''D-Pad''' again will end the effect. On [[Xbox LIVE|Xbox Live]], the trick can also be performed by exhausting all grenades and holding '''L''' ('''Left Trigger''').

In ''Halo 2'', not all weapons can be put into ready position, such as [[dual wielding|dual-wield]] weapons, [[H2:Rocket Launcher|Rocket Launchers]], and [[H2:Energy Sword|Energy Swords]]. The trick seems to work on two-handed rifle type weapons, as when the [[H2:Brute Shot|Brute Shot]] is lowered, but on closer inspection, the player's arm is bent slightly and the Brute Shot itself is slightly tilted.

The ''Halo 3'' alert carry was first performed in public by ''Red vs Blue'' cast members. In ''Halo 3'', the feature is activated with a button combination. The player can cease fire by pressing and holding the following in any order (different according to button layout):

After holding the combination together for three seconds, a player will find that their weapon has disappeared off of their screen; the weapon is lowered and visible to other players. Some weapons, however, are barely or not at all affected by this trick; such weapons include the [[H3:Energy Sword|Energy Sword]], [[H3:Brute Shot|Brute Shot]], [[H3:Gravity Hammer|Gravity Hammer]], [[H3:Sentinel_Beam|Sentinel Beam]], [[H3:Plasma Cannon|Plasma Cannon]], [[H3:Machine Gun Turret|Machine Gun Turret]], and [[H3:Flamethrower|Flamethrower]]. The trick looks odd when performed with the [[H3:Rocket Launcher|Rocket Launcher]], [[H3:Fuel Rod Gun|Fuel Rod Gun]], [[H3:Spartan Laser|Spartan Laser]], and dual-wielded weapons.

The animation of the Rocket Launcher, Fuel Rod Gun, and the Spartan Laser will look similar to that of the assault rifle in ''Halo: Combat Evolved'' (unless the player uses an Elite model, then there's no change). If a player is dual-wielding, looking around will desynchronize their hands.

Shooting, throwing grenades, [[H3:Melee|meleeing]], going into Edit Mode on [[H3:Forge|Forge]], dying or re-entering the button combination will end the effect.

The alert carry option returned in ''[[Halo: Reach]]'' and was first seen being used in the [[Red vs. Blue Halo: Reach PSA: Deja View]]. The player can alert carry by pressing and holding the following in any order (different according to button layout):

After holding the combination together for three seconds, a player will find that their weapon has disappeared off of their screen; the weapon is lowered and visible to other players. Like in ''Halo 3'', players will be unable to perform it on Xbox LIVE.{{Ref/YouTube|0JfHzHgneK0|VideoName=Easier Way to Lower Weapon on Halo: Reach}}

Unlike ''Halo 3'', the [[Reach:Rocket Launcher|Rocket Launcher]], [[Reach:Fuel Rod Gun|Fuel Rod Gun]], [[Reach:Gravity Hammer|Gravity Hammer]], and the [[Flag]] will be in a resting position after using alert carrying.

Unlike previous games, when the player alert carries while holding a detached turret, the camera angle will shift a bit and the Spartan will also appear to be slightly more relaxed. It is also possible to use alert carry in the campaign.

== ''Halo 4'' ==
Pre-release screenshots revealed that alert carry had been incorporated into ''Halo 4''. The player can alert carry by pressing and holding the following in any order (different according to button layout):
