'''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.

==Description==
Set on one of the many cliff sides of Alpha Halo, this beacon 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 name="THB11911">[http://blogs.halowaypoint.com/Headlines/post/2011/11/09/The-Halo-Bulletin-11911-.aspx ''Halo Waypoint'': THE HALO BULLETIN: 11.9.11] ([https://web.archive.org/web/20130430191758/http://blogs.halowaypoint.com/Headlines/post/2011/11/09/The-Halo-Bulletin-11911-.aspx Archive])</ref>

==Locations==
The following are locations on the map that are so named on the player's [[heads-up display]] during gameplay:
*Landslide
*North Drop Zone
*Field
*Station 1
*Station 1 Interior
*East Drop Zone
*Station 2
*Station 2 Interior
*Gateway
*South Drop Zone
*West Drop Zone
*West Ramp
*East Ramp
*Upper Deck

==Tactics==
*The best place to stay in for this map is the central structure. Even though the player would have the higher ground as well as back up, there are four openings for the Covenant: the west ramp, the east ramp, the man cannon, and the tunnel leading to the upper deck. One player might need to patrol around, but four players could cover all entrances.
*Unlike most Firefight levels, there are five [[health pack]]s in the entire map and their locations are quite separated around the map. One is right next to the ammunition crate on the "Upper Deck", another is in the tunnel leading to "Upper Deck", the third one is on a wall directly ahead of the initial spawn area, one next to some green lights batons on the "Field", and the last one is in "Station 2 Interior". Having [[Drop shield]] as the [[armor abilities|armor ability]] would be a good idea.
*The ODSTs are not invincible, and will die from too much fire. If you want them to be more contributive in defending the area, give them better weapons. The ODSTs with DMRs should be the first ones to acquire better weapons, since the DMRs are only useful when the projectile is aimed at the target's head, and the AI isn't programmed to make accurate headshots. 
*Watch out for the Banshee, it will fire its weapons at you if you get in its sights. Destroy it when you are free, since it also worth some points and [[credit]]s.
*The Warthog is useful in this large map, but don't drive into the tight spaces. Grenades and heavy weapons will destroy this useful asset if the Covenant are given the opportunity. Also watch out for the [[Sangheili]] and [[Jiralhanae]], since they can board and kill the ODST manning the turret.
*When you are away from the central structure (either for driving the Warthog or collecting weapons), Covenant troops who are able to man the [[M247H Heavy Machine Gun|heavy machine gun]] will use it against you, and it can kill you within a few seconds.
*When the [[Dextro Xur-pattern Spirit|Spirit]] drops troop near the man cannon, the troops would usually converge around the cannon, so use the [[H-165 Forward Observer Module|Target Locator]] when you think you can kill most of them. 
*Players can use the Warthog and Mongoose to block the side ramps, funneling the Covenant to the far end. The Covenant will not attempt to climb over the vehicles, though Brutes will sometimes knock the Mongoose out of the way. The player can also use the antenna at the far end of the structure. This tactic is particularly useful in [[Score Attack (Halo: Reach gametype)|Score Attack]] as it limits the Covenant's access to the top of the structure and prevents the player from being surrounded.

==Friendly AI==
[[File:HR Installation04 ODSTs 1.png|thumb|300px|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 name="bulletin">[http://halo.xbox.com/en-us/news/headline/the-halo-bulletin-9811-/230739 ''Halo Waypoint: The Halo Bulletin: 9/8/11''] ([https://web.archive.org/web/20110926213957/http://halo.xbox.com/en-us/news/headline/the-halo-bulletin-9811-/230739 Archive])</ref>
*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 name="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.
