The '''Controller Sentinel''' is a [[Forerunner]] [[Sentinel]] designed for the defense of valuable technology on Forerunner installations.{{Ref/Site|Id=CFFrosty|URL=https://www.halowaypoint.com/en-us/news/stay-frosty|Site=Halo Waypoint|Page=Canon Fodder - Stay Frosty|D=30|M=10|Y=2022}}{{Ref/Book|Id=Enc22|Enc22|Page=329}}

==Overview==
===Design details===
Similar to the roles of the [[Enforcer Sentinel]]s, the Controllers are deployed to guard key locations and counter escalating threats on a given installation. Where they differ is that the Enforcers are strictly intended for use in fighting outbreaks of the [[Flood]] parasite, whereas Controllers are tasked to guard key sites and technologies. They are restricted in their mobility, and are effectively "tethered" within a set radii of their charges.{{Ref/Reuse|CFFrosty}}{{Ref/Game|Id=PL|HW2|Phoenix Logs|Detail=Controller Sentinel}} Controllers are only awakened in the event that an installation-compromising threat is detected.{{Ref/Reuse|Enc22}}

===Armaments===
Controllers are equipped with a supercharged [[Sentinel pulse|wide-area pulse field emitter]] as its primary weapon and a [[Sentinel beam|persistent beam projector]] as its secondary weapon (to prevent enemies from hiding in its blind spot). For defense, they are equipped with forward-facing [[energy shield]]ing - an improvement of the ones used by the Enforcers.{{Ref/Reuse|CFFrosty}}{{Ref/Reuse|PL}}{{Ref/Reuse|Enc22}}

==Operational history==
Controllers were developed in [[2559]] in response to the outbreak of the [[Second Ark Conflict]] between the [[Banished]] and {{UNSCShip|Spirit of Fire}} on [[Installation 00]]. Their development was a response to counter the escalating threats encountered in the fighting, used to guard key sites of importance.{{Ref/Reuse|CFFrosty}}{{Ref/Reuse|PL}} In May of that year, they were first encountered by ''Spirit of Fire'' forces during [[Operation: SPEARBREAKER]]. During the mission, a task force led by [[Sunray 1-1]] fought against multiple Controllers guarding the region surrounding the construction and launch site for a {{Class|Despair|fighter}} and its [[design seed]], alongside the [[charging column]]s supporting it.{{Ref/Level|HW2|Gatecrashers}}{{Ref/Level|HW2|Not on My Watch}}

==In-game information==
===''Halo Wars 2''===
Controller Sentinels are only encountered in the ''[[Halo Wars 2: Operation: SPEARBREAKER]]'' campaign. They can be fought as enemies in the levels [[Gatecrashers]] and [[Not on My Watch]].

==Production notes==
The Controller Sentinel made its debut in the ''[[Halo Wars 2]]'' expansion ''[[Halo Wars 2: Operation: SPEARBREAKER|Operation: SPEARBREAKER]]''. The Sentinel's early concept passes were done by [[:Category:Images by Bill Yi|Bill Yi]], and originally explored the inclusion of the [[Enforcer]] Sentinel from ''[[Halo 2]]''.{{Ref/Site|Id=BillYiArtStation|URL=https://www.artstation.com/artwork/mqD4N1|Site=ArtStation|Page=Bill Yi: Halo wars2|D=12|M=02|Y=2021}}{{Ref/Site|Id=BillYiSite|URL=http://billyiart.com/#/new-page-5/|Site=Art of Bill Yi|Page=Halo Wars 2|D=12|M=02|Y=2021}} Over time, these explorations seemed to evolve into the final Controller design done by [[:Category:Images by Theo Stylianides|Theo Stylianides]].{{Ref/Site|URL=https://www.artstation.com/artwork/v2rO2E|Site=ArtStation|Page=Halo Banished|D=12|M=03|Y=2022}} During some of the later concept pieces, the Sentinel appears to have been given the preliminary name "Forerunner Scourer" before the final Controller name was settled on.

In the later expansion ''[[Halo Wars 2: Awakening the Nightmare|Awakening the Nightmare]]'', a [[Cut Halo Wars 2 units|cut variant]] of the Controller Sentinel can be found unused in the game files. Unlike the versions featured in the ''Operation: SPEARBREAKER'' expansion, it has no shields. Artwork for the mission [[What Could Go Wrong?]] show three such Sentinels attacking [[Voridus]]' [[Barukaza Workshop Scarab|Scarab]], indicating it may have at one point been intended to appear in this level.
