Constructors are devices similar to Sentinels in design that mainly repair damage to any Forerunner structure they find, using weak energy beams similar to [[Sentinel Beam]]s. The beams are lethal if in direct contact with an organism. This is unknown to the Constructor though. They are similar in appearance to the [[Covenant]] [[Plasma Rifle]].
Constructor Sentinels are drones programmed to repair any damaged [[Forerunner]] structure they can find, using low-tuned [[reconstitution emitter]]s.{{Ref/Reuse|Enc22P327}} These reconstitution beams are fired from either the top half, the middle or the bottom half of the Constructor.{{Ref/Note|In ''Halo 2'', Constructors of Installation 05 fire their beam from their upper body, in ''Halo 3'', the Constructors of Installation 00 fire their beam from their lower body, and in ''Halo 5: Guardians'', the Constructors fire their beam from the middle of their body.}} The beams can also be used to open [[Cryptum]]s<ref>'''Halo 5: Guardians''', campaign level, ''[[Guardians]]''</ref> or lower the shields on [[piston]]s, allowing them to access the tunnel networks built within the [[Sentinel Wall]].{{Ref/Reuse|sacred icon}}<ref name="isolation">'''[[Halo 3]]''', multiplayer level ''[[Isolation]]''</ref> Although weak, one of these beams can harm an organism if they come in contact with it.{{Ref/Reuse|sacred icon}}


The Sentinels will come to their aid if they are attacked, as they are ill-suited for combat, having no weapon systems of their own. However, their beams will damage you if you get caught in the path (on Legendary difficulty their beams can kill in seconds, but are still not powerful enough to cause complete and devastating death). They also use their beams to lower the shields on [[piston]]s, allowing them to move throughout the [[Sentinel Wall]] quickly. Constructors are encountered only during the levels [[Sacred Icon (Level)|Sacred Icon]] and the [[Quarantine Zone (Level)|Quarantine Zone]] and are distantly visible on the ''[[Halo 3]]'' multiplayer maps, [[Isolation]] and [[Construct]], but they can be seen on [[The Ark (Level)]] (where the light bridge must be activated) and [[The Oracle (Level)|The Oracle]].<ref>''[[Halo 2]]'', level [[Sacred Icon (Level)|Sacred Icon]]</ref>
Constructors can also play the role of a security grid. When a Constructor is attacked, a signal is automatically sent to [[Sentinel launcher]]s to begin deploying Aggressors. For this reason, they form an excellent security perimeter. However, with no weapons systems of their own, the Constructors must rely on Aggressors when threatened.{{Ref/Reuse|sacred icon}}
[[Image:H3 Constructor.jpg|right|thumb|A Constructor on [[Installation 00]]'s Cartographer]]
They first appear in the opening moments of "Sacred Icon", where a swarm of them flies about trying to fix the platform you start on, then moves away further into the Installation.  They don't really affect anything in game, they show red on your reticule and you may shoot them if you like although they wont bother you.


When they appear in the "Quarantine Zone" level, they appear at the end of the level, when the player fights Flood-controlled [[Scorpion]] and [[Wraith]] tanks along with many [[Flood]] using [[Covenant]] [[Ghost (Vehicle)|Ghosts]] and a [[Spectre]]. Two Sentinel [[Enforcer]]s fight against the Flood near a downed [[Human]] [[Pelican]] dropship. During all this chaos, if the player watches one of the large and deep trenches, a large cloud of Constructors fly off into the sky.
One or more Constructors will often be summoned if something within their facility is damaged. Once attracted, they appear to require little prompting to follow someone seeking their assistance, as [[Fireteam Osiris]] simply had to state that they had a task for a Constructor to get it to follow them, with no other obvious methods of coercion being used.<ref>'''[[Halo 5: Guardians]]''', campaign level ''[[Enemy Lines]]''</ref> Constructors can be programmed for other tasks such as awakening a [[Guardian]] with little difficulty, being reprogrammed within minutes rather than hours or days as might be expected to happen with other technology.<ref>'''[[Halo 5: Guardians]]''', campaign level ''[[Before the Storm]]''</ref>

===''Halo 2''===
[[File:H2A SentinelBois.png|250px|thumb|A Constructor alongside two Aggressors on ''Sacred Icon''.]]
Constructors make their first appearance in the ''[[Halo 2]]'' level ''[[Sacred Icon]]'', exactly beside where [[Thel 'Vadamee]] stands after he is dropped off from his [[Phantom]]. They are repairing the destroyed edge and will leave after a while, or if the Arbiter approaches them. Attacking them will result in being attacked by Aggressors.


In the level ''[[Quarantine Zone]]'', they appear at the end of the level when the player fights the [[Flood]]-controlled [[M808B Scorpion|Scorpion]] and [[Zurdo-pattern Wraith|Wraith]]s along with many Flood [[combat forms]] using Covenant [[Karo'etba-pattern Ghost|Ghosts]] and two [[Enforcer]]s fight against the Flood near a downed [[UNSC]] [[D77-TC Pelican|Pelican]] dropship. If the player watches one of the large and deep trenches, a large cloud of Constructors can be seen flying off into the sky.

===''Halo 3''===
[[Category:Technology]]
In ''[[Halo 3]]'', they appear in the level ''[[The Ark (level)|The Ark]]'', where they are seen inside Forerunner structures, including inside the [[Sentinel Wall|wall]] to the [[Cartographer]] and the map room itself.
 
They can be also found in the [[multiplayer]] maps of ''[[Isolation]]'' and ''[[Construct]]'', where they can be seen flying around in the distance.
 
With the addition of the ''[[Halo Online]]'' multiplayer map [[Edge]] to the Halo component of ''[[Halo: The Master Chief Collection]]'', a flock of Constructors can be found maintaining the databanks in the rear of the Forerunner structure where the map is set.
 
===''Halo 5: Guardians''===
In ''[[Halo 5: Guardians]]'', Constructors play a significant role in the campaign. In the level ''[[Unconfirmed]]'', [[Fireteam Osiris]] encountered Constructors in the mines on [[Meridian]] near where the [[Guardian]] was. Though the team noted that the Constructors were similar in design to a [[Monitor]], they were non-communicative and uninterested in the humans, so [[Jameson Locke]] ordered his team to keep an eye on the Constructors but to otherwise ignore them.
 
Later, in the level ''[[Enemy Lines]]'', [[Fireteam Osiris]] is tasked with acquiring a Constructor in order to activate the [[Guardian]] on [[Sanghelios]]. Osiris is able to find one in a support facility for the Guardian, attracting its attention by damaging a terminal in the facility. Dr. [[Catherine Halsey]] is then able to use Forerunner technology in the area to program the Constructor with the recording made of the Guardian on [[Meridian]]. Though Halsey thought it would take hours to days, the Constructor is programmed quickly and flies off to awaken the Guardian.
 
In the final mission ''[[Guardians]]'', [[Genesis]] [[Monitor]] [[031 Exuberant Witness]] summons a swarm of Constructors to retrieve the [[Cryptum]] that [[Blue Team]] was trapped in by [[Cortana]] after Osiris manages to restore control over Genesis to Exuberant Witness. Under the control of Exuberant Witness, they use their beams to open the Cryptum and free the Spartans of Blue Team.
 
==Trivia==
*On [[Isolation]] and [[Construct]], the Constructors can be sniped, though their small size and constant movement make this difficult.
*In ''Halo 2'' and ''Halo 3'', even though Constructors do not attack you, your weapon reticule will turn red when passed over them.
*A player can get up close and even touch a Constructor on Construct. First, they must overload the map with [[TR/9 Antipersonnel Mine|trip mines]]. When the map is overloaded, the player must go through the hole where the purple lift beams are projected. A player then can easily be touched by a Constructor, but cannot be moved. They can be destroyed, mainly with a [[M6 Spartan Laser|Spartan Laser]] or a [[M7057 flamethrower|Flamethrower]]. Note that even when one is destroyed, another will immediately replace it in the same place. So, in other words, you will see the debris from a destroyed Constructor fall from a full and complete one.
*In ''Halo 2'', the glow is on the top part of the Constructor. In ''Halo 3'', it is on the bottom.
