Editing Coordinated Stage

{{Era|Forerunner|HCW|}}
The '''Coordinated Stage''' is the second stage of a [[Flood]] infestation, over the course of which a local ecosystem is typically fully absorbed. During this stage, Flood population rapidly increases. The [[Flood Super Cell]] generates a [[Flood hive|hive]] and propagates [[Flood spore|spores]] into the local atmosphere in massive numbers. Once sufficient biomass has been gathered, the Flood gains the ability to spontaneously generate Flood Super Cells, removing its dependency on hosts and giving rise to [[Flood pure form|pure forms]].<ref name="wp flood">[https://www.halowaypoint.com/en-us/universe/species/flood '''Halo Waypoint''': ''Flood'']</ref> On the verge of initiating the Coordinated Stage, the [[proto-Gravemind]] continues to be built until it reaches the status of a complete Compound Mind — a [[Gravemind]]. It is at this point that the Flood becomes significantly more organized (communicating via thoughts and attacking strategically) and subsequently more lethal than in the preceding [[Feral Stage]].<ref>''[[Bestiarum]]''</ref> Upon the formation of a full Gravemind, all locally available [[Sentience|sentient]] beings have typically been absorbed by the Flood.<ref name="wp flood"/>

Once it has gained sufficient technology, the Flood will proceed into the [[Interstellar Stage]].

==Occurrences==
This stage has occurred several times;

*The first was during the Flood's initial rise in the [[ancient human]]s' dominion during the events preceding the [[human-Forerunner wars]]. After infesting the human pets known as [[Pheru]], the Flood began to infect humans and [[San'Shyuum]], eventually initiating the Coordinated Stage on many human worlds.

*The Gravemind's conception from the planet of [[Seaward|G617g]] gave rise to the Gravemind who made [[Forerunner-Flood war|war with the Forerunners]] and was believed to be destroyed during the first firing of the Halo Array.

*During the [[Human-Covenant War]], ''[[Infinite Succor]]'', an [[agricultural support ship]] which was part of the [[Fleet of Particular Justice]], was targeted by the Flood.<ref>'''[[Halo Graphic Novel]]''', ''[[The Last Voyage of the Infinite Succor|Last Voyage of the Infinite Succor]]''</ref> The on-board [[Minister of Etiology|Legate]] eventually became part of the biomass reserves being built on the ship by Combat Forms – it is believed to have been in the process of transforming into a proto-Gravemind before [[Rtas 'Vadum]]ee sent the vessel into the nearest star.

*Not far away on the ''[[Truth and Reconciliation]]'' orbiting above [[Installation 04]], [[Jacob Keyes|Captain Jacob Keyes]] had become an anchor for what appeared to be a proto-Gravemind. This entity, however, had been taken care of as the Master Chief obtained the Captain's [[neural interface|neural implants]] and the proto-Gravemind was later destroyed by Covenant Spec Ops units.

*At some point, a catastrophic containment failure on [[Installation 05]] released the Flood into the [[Quarantine Zone]] around the [[Library]], which eventually facilitated the creation of a proto-Gravemind. This became the last known [[Gravemind]], the one that existed during the rest of the Halo trilogy. This infestation expanded into the interstellar stage before the Gravemind and all escaped Flood forms were destroyed, reverting any Flood left in the galaxy back into the feral stage.

==Trivia==
*This is the stage that most resembles the Flood in ''[[Halo 2]]''.
*The Flood in ''[[Halo: Combat Evolved]]'' were always found without whatever attire their hosts usually wore. In ''Halo 2'', however, this changed, as the Flood then kept the apparel of their hosts for protection, likely a trait of the Coordinated Stage.
