{{Article quote|Fight for survival around mysterious Forerunner structures on Installation 04.}}

'''Installation 04''' is a [[Firefight]] map included in the [[Anniversary Map Pack]] for ''[[Halo: Reach]]''. The level is based on the cliff edge section of the [[campaign]] level [[Halo (Halo: Combat Evolved level)|Halo]] from ''[[Halo: Combat Evolved]]''. Friendly AI — [[Orbital Drop Shock Trooper|ODST]]s — will aid the player in both solo and [[cooperative play]]; this is the first time that friendly NPCs have appeared in a Firefight map.

==Universe and lore==
Set on one of the many cliff sides of Alpha Halo, this [[beacon tower]] served as a rendezvous point for survivors of the Covenant attack on the {{UNSCShip|Pillar of Autumn}}. These survivors, including the legendary Orbital Drop Shock Troopers, were forced to stave off numerous [[Covenant]] attacks until rescue finally came.{{Ref/Site|Id=THB11911|URL=http://blogs.halowaypoint.com/Headlines/post/2011/11/09/The-Halo-Bulletin-11911-.aspx|Site=Halo Waypoint|Page=The Halo Bulletin: 11.9.11|D=30|M=04|Y=2013}}

==Friendly AI==
[[File:HR Installation04 ODSTs 1.png|thumb|300px|right|ODSTs defending the beam emitter from Covenant attackers.]]
Installation 04 is the first and - to date - only Firefight map to contain friendly AI alongside enemy counterparts. These allies take the form of a squad of four Orbital Drop Shock Troopers. The ODSTs spawn in the top of the structure and will not leave unless pushed off, or the difficulty is set to [[Easy]]. ODSTs will only enter vehicles such as the [[Warthog]] when the Warthog is spawned in via [[D77-TC Pelican]] dropship. Elite players in Firefight Versus are unable to perform assassination animations against the ODSTs; they can only perform the traditional one-hit kill from behind.

==Trivia==
===Production notes===
*While selecting maps for inclusion in the Anniversary map pack had been difficult, choosing a Firefight map was a relatively straightforward process. Both the teams at [[Certain Affinity]] and [[343 Industries]] independently came up with the idea to base a level around the "Halo" mission from ''Halo: Combat Evolved'', as the level featured Firefight-esque locales already - defendable bases and Covenant wave defense. The cliffside was chosen as the location to model due to the space to maneuver for AI and players.{{Ref/Site|Id=bulletin|URL=http://halo.xbox.com/en-us/news/headline/the-halo-bulletin-9811-/230739|Site=Halo Waypoint|Page=The Halo Bulletin: 9.8.11|D=26|M=09|Y=2011}}
*The idea of including friendly NPCs originated when Certain Affinity was developing the [[Defiant Map Pack]]. They had experimented with the idea of adding friendly AI units to ''[[Unearthed]]'' but did not have time to implement them into the final map.{{Ref/Reuse|bulletin}}
===Miscellaneous===
*The design of the Forerunner [[Beacon tower]]  found on this level is noticeably different from the one seen in the remastered campaign. Rather than have the beams of energy shoot out of the structure from underground, they are emitted by a large turbine-like structure which emits bursts of energy upon reaching high enough speeds.
*Due to the fact that AI is almost never present at the same time as Man Cannons, the AI tend to hesitate before entering them.
*At the part of the map where in the [[Halo (Halo: Combat Evolved level)|campaign level]] the marines are hiding, [[343 Guilty Spark]] can be seen flying back and forth between the two doors.
**In some cases, one may see a (non-functional) prompt to exchange weapons with Spark, who is shown as holding a [[Focus Rifle]].<ref name="spark-with-rifle">[http://www.youtube.com/watch?v=XFCokLAZs_4 ''YouTube: Halo: CEA - 343 Guilty Spark Easter Egg on Installation 04'']</ref> This seems to be related to a [[Forge]] bug involving [[Monitors]], desyncs, and Focus Rifle beams.
*The radio set found on this level is indestructible.
*This is the only map in which one of the weapon drops is a Warthog. This Warthog is brought in by a Pelican.
*If pan cam is used, the player will find the [[GA-TL1 Longsword]] that performs the supply drop at the edge of the map. Curiously enough, even when supply drops are disabled, the Longsword will still spawn, but will be frozen and remain where it is. The Longsword is not a physical object however, and is not fully textured.
