[[File:Rep-Installation04_Control_Room_Overview.jpg|thumb|250px|Control Room of [[Installation 04B]].]]

A '''control room''' is a crucial facility featured on many [[Forerunner]] installations, most prominently those of the [[Halo Array]]. The control room of a Halo contains the installation's [[Core]] data center, and is where the [[Activation Index|Index]] is used to activate the ring's primary weapon. It is typically located within a pyramidal temple-like structure.<ref name="twoB">'''Halo: Combat Evolved''', campaign level ''[[Two Betrayals]]''</ref> These facilities are featured on other installations as well; [[shield world]]s, for example, possess dedicated control centers for the [[Forerunner fleet]]s or weapons they may contain.<ref name="evg">'''[[Halo: The Essential Visual Guide]]''', ''page 35''</ref>

==Installation 03==
{{main|Control Room (Installation 03)}}
The interior of [[Installation 03|Gamma Halo]]'s control room resembles that of Installation 04 in general layout. It was here that John-117 defeated the [[Ur-Didact]] following the [[New Phoenix Incident]]. The Master Chief utilized the ring's activation index to manually disabled the installation's safety protocols, allowing monitor [[859 Static Carillon]] to eject the fragment of the ring housing the control room into the planet below, seemingly incinerating the Didact in the impact but keeping the control room intact.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 10|Issue #10]]''</ref> 

==Installation 04==
{{main|Control Room (Installation 04)}}
Installation 04's Control Room was a [[Wikipedia:Ziggurat|ziggurat]]-like structure located in a snowy chasm. The main console and Core was located within a massive spherical chamber behind a set of [[door]]s and connecting corridors. The room features a massive [[Holography|hologram]] of Installation 04 and the [[Threshold]] system in its center. Suspended in the air is a large circular catwalk.<ref name="twoB"/>

The [[John-117|Master Chief]] reached the main console and inserted [[Cortana]], who sent him to the installation's [[Flood containment facility]] to attempt to stop [[Jacob Keyes|Captain Keyes]] from unleashing the Flood.<ref>'''Halo: Combat Evolved''', campaign level ''[[Assault on the Control Room]]''</ref> He returned to the Control Room at the start of [[Two Betrayals]] to insert the Index as prompted by [[343 Guilty Spark]], but was stopped by Cortana. 343 Guilty Spark then sent [[Sentinel]]s to stop the Chief. After the Chief destroyed the Sentinels, he took Cortana and left.<ref name="twoB"/>

==Installation 05==
{{main|Control Room (Installation 05)}}
[[Installation 05]]'s Control Room is located on an offshore island in a large body of water. It bears significant structural differences from Installation 04's room.<ref name="TgreatJ">'''Halo 2''', campaign level ''[[The Great Journey]]''</ref>

Here, the [[Jiralhanae Chieftain]] [[Tartarus]] brought [[Miranda Keyes]] to the Control Room along with [[343 Guilty Spark]] to attempt to activate Delta Halo. He succeeded in initiating the activation sequence of the installation, but was slain by [[Arbiter]] [[Thel 'Vadam]]ee and [[Avery Johnson|Sergeant Johnson]]. The Index was removed by Miranda before the weapon could fire. Upon activation of the firing sequence, the control room's central chamber reconfigured from its inert state into a three-leveled structure with a [[gravity lift]] in the middle.<ref name="TgreatJ"/>

==Installation 04B==
{{Main
|1=Control Room (Installation 04)
|l1=Control Room (Installation 04B)
}}
The Control Room for the [[Installation 04B|replacement Installation 04]] is a nearly identical copy of the original ring's Control Room. The temple structure has the same basic triangular shape as Installation 04's Control Room, with a long support beam running from the ground to the top of the structure. There are minor aesthetic differences, including the walkways on each level being more narrow, as well as the tower at the top being replaced by a large flat landing.<ref name="hh3">'''Halo 3''', campaign level ''[[Halo (Halo 3 level)|Halo]]''</ref>

Inside the control room, the corridors and doorways are reminiscent of Installation 04, while offering minimal changes. The actual control room and control panel is scarcely different from the original. The large dome-shaped room still shows a holographic image of the Halo ring, although Threshold is missing from this image (as the ring has not been moved to that point).<ref name="hh3"/>

The differences in design from the original Installation 04 may be due to the ring's incomplete state, as suggested by Cortana's observation, "Halo. It's so new...unfinished."<ref name="hh3"/>

==Shield World 0459==
{{Main|Apex Site}}
[[Shield World 0459]]'s [[Apex Site]] was classified as a form of control room.<ref name="evg"/> This facility was an elongated platform suspended in the air high above the interior surface of the miniature [[Dyson sphere]], surrounded by docking towers housing [[Forerunner dreadnought]]s. At one end of the platform was a control panel which, like many Forerunner artifacts, could only be operated by a [[Reclaimer]].<ref>'''Halo Wars''', campaign level ''[[Beachhead]]'' (opening cutscene ''"Judgment Day"'')</ref>

==Trivia==
{{Linkbox|gallery=yes|gallerypage=Images of Control Room}}
*The control room was first seen in the [[pre-Xbox Halo]] demo in 1999. In the video, the control room was about one-third the size of the version later seen in ''[[Halo: Combat Evolved]]''.
*It is most likely that the appearance of the Control Rooms differ with each Installation, since the design of the one found on Installation 04 bears little resemblance to that of Installation 05. Given that not all of the Halo rings known to have existed were built concurrently, it is possible that Installation 05's design was of an earlier or later version than that of Installation 04.
