A '''Flood hive'''<ref>'''[[Halo 3]]''', campaign level ''[[Floodgate]]''</ref> is an important step in the development of the [[Flood]] life-cycle. The processes that develop a hive begin during the [[Coordinated Stage]] of Flood development, once a viable Gravemind has been developed and the Flood has access to a sizable population. The Gravemind is a collection of the sentience and knowledge that has been gathered by the victims of the [[Pod infector|Flood parasites]]. Once a hive has been established, it serves as a base for Flood assaults as well as housing a Flood [[Gravemind]]. Two notable examples of Flood hives in the modern era include ''[[High Charity]]'' and the ''[[Indulgence of Conviction]]''.

==Creation==
===Early stages===
In order for a hive to be founded, the Flood must have access to a suitably large populace and an environment capable of sustaining Flood life. The population of the area has to contain high enough calcium deposits to sustain the Flood parasite.

Once a useful area has been found, the Flood proceed to attack the hosts present, gathering food and biomass. The Flood attack with a strategy relying primarily on numerical superiority. The parasite then begins to pump [[Flood spores|spores]] into the atmosphere,<ref>'''[[Halo 2]]''', campaign level ''[[High Charity (level)|High Charity]]''</ref><ref>'''[[Halo: Combat Evolved]]''', campaign level ''[[The Library]]'', ''[[343 Guilty Spark (level)|343 Guilty Spark]]'' ('''[[04-343 Guilty Spark]]''': ''"[[MJOLNIR Powered Assault Armor/Mark V|Your environment suit]] will serve [[John-117|you]] well when the Flood begin to alter the atmosphere. You are a good planner!"'')</ref> restricting breathing for the hosts present, causing them to die of asphyxiation, or weakening them in order to make them less resistant to assimilation.  This is accomplished, at least in part, through the creation of structures known as spore mountains. These peak-like agglomerations of biomass are used to generate Flood spores and release them into the atmosphere. There are known instances of spore mountains reaching hundreds of kilometers in diameter and dozens in height.<ref>'''Halo: Silentium''', ''page 82''</ref>

Hosts who are infected will add to the Flood's arsenal. Older [[Flood combat form|combat forms]] will develop into [[Flood carrier form|carrier forms]], which generate more infection forms, continuing the cycle. During this time, [[Flood blister]]s start to grow on surfaces. Growth pods are constructed from the flesh of infected life forms not converted into [[Flood combat form|combat forms]], and grow at an extraordinary rate.<ref>'''[[Halo Wars 2]]''', ''[[Phoenix Logs]]'' - Blister</ref>

===Later stages===
Once the Flood has access to enough calcium, they begin to develop a hardened carapace, onto which they add [[LF.Xx.3273 Flood Super Cell|Flood Super Cells]] to form [[Flood pure form|pure forms]], a form of independent Flood drone which has no need for a host. As a result of this development, combat forms are relegated to defensive positions or are converted into more pure forms.<ref>'''Halo 3'''</ref>

The functions of objects, such as [[door]]s, are [[Porta|replaced]] as Flood biomass grows over the original architecture. Under the Gravemind's direction, life support systems are sabotaged in order to speed up the demise of the inhabitants.<ref>'''Halo 2''', ''[[Dialogue Placeholders]]'' ('''[[Cortana]]''': ''"Flood spores have contaminated the city's life-support infrastructure, the filtration systems are overloading!"'')</ref> The pouch forms eventually consume most or all of the original area. The growth pods grow large, bubble-like growths, which incubate new infection forms, essentially replacing carrier forms and further reducing the Flood's dependence on hosts.

Once the process is complete, the Flood disposes of almost all need for new biomass, becoming self-sustaining. Despite this, due to the Flood's natural instinct to infect and consume all life, the parasite rarely becomes content at this stage.

==Trivia==
*Interestingly, there seems to be less green mist in the later stages of Flood hive creation. This is easily noticeable from the ''[[Halo 2]]'' level ''[[High Charity (level)|High Charity]]'' to ''Halo 3'' level ''[[Cortana (level)|Cortana]]''. It is possible that all the Flood spores floating in the air settled down and created the hive. Alternatively, it's possible the spores are primarily used to exacerbate the conversion rate of uninfected environments; thus, having an excess of spores in a Flood hive would be redundant.
