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 AI, such as 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 AI originated when Certain Affinity was developing the Defiant Map Pack. They had toyed with the idea of adding friendly AI units to Unearthed but didn't have time to implement it into the final map.
