Installation 04 (map)

Installation 04 is a Firefight map included in Halo: Combat Evolved Anniversary for Halo: Reach. The level is based on the cliff edge section of the campaign level Halo from Halo: Combat Evolved. Friendly AIs, ODSTs, will aid the player, on both solo and cooperative play. This is a brand new feature to Firefight included with Installation 04.

Trivia

 * 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.
 * 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.
 * The design of the Forerunner Beacon 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 campaign level the marines are hiding, 343 Guilty Spark can be seen flying back and forth between the two doors. Oddly enough, he appears to have a Marathon symbol within his "eye" despite the fact that 343 Industries deliberately omitted this feature with Halo: Combat Evolved Anniversary ' s campaign.
