'''Flood blisters''',{{Ref/Reuse|enc22}}{{Ref/Game|Id=PL|HW2|Phoenix Logs|Detail=Flood blister}} also referred to as '''Flood eggs'''{{Ref/Game|HW|in-game unit}} or '''Flood growth pods''',{{Ref/Site|Id=bnet|URL=http://www.bungie.net/inside/publications.aspx|Site=Bungie.net|Page=Inside Bungie - Publications|Detail=Halo 3 Flood Alien Level Autopsy|D=3|M=2|Y=2009}} is a type of [[Flood]] [[infection form]]s. They are large, bulbous sacs that contain other infection forms—typically [[pod infector]]s—and their membranes also function as incubation chambers for the development of [[Flood spore|spores]].{{Ref/Reuse|enc22}}

==Overview==
===Physical characteristics===
Blisters are created from non-[[Sentience|sapient]] creatures or mangled corpses that have been deemed unfit for transformation into [[Flood combat form|combat forms]]; after being seeded with [[Flood Super Cell|Flood cells]], the biomass rapidly transform into Flood blisters.{{Ref/Reuse|PL}} Their shapes and sizes vary, depending on what best fits the environment they are created in. However, most are pale sickly colored ovoid bulbs that distend from the Flood's existing membrane. Blisters in the incubation period may have a thin layer of skin, whereas matured blisters appear to have shed the skin, emitting a sickly yellow glow.{{Ref/Reuse|enc22}} 

===Function===
Flood blisters typically grow on walls and floors—adhered to surfaces using suction-cup-like appendages{{Ref/Level|H3|Cold Storage}}{{Ref/Twitter|Id=vic|vicdeleon|1574179376085999616|Vic DeLeon|Quote=And he’s my Mudbox sculpt of the spore sac, affectionately known as “Vic’s boo-bag” by @cgbarrett and @docabominable|D=26|M=9|Y=2022}}—and particularly on surfaces covered with Flood biomatter;{{Ref/Level|H3|Floodgate}}{{Ref/Level|H3|Cortana (level)|Cortana}} as such, they are a common sight in the [[Blightlands]],{{Ref/Level|HW2|Light the Fuse}} where they grow on surfaces as well as [[Flood stalk]]s.{{Ref/Level|HW|The Flood (level)|The Flood}} They have no means of defense, but if ruptured, they explode and release their infectious spores and their infection forms.{{Ref/Reuse|PL}} Given the Flood's highly infectious nature, blisters are considered one of the most pernicious aspects of the Flood, harboring the potential to transform an entire planet's biosphere if left unchecked.{{Ref/Reuse|enc22}} [[Flood bomber form]]s are also known to release Flood blisters.{{Ref/Book|Enc22|Page=409}}

==Gameplay==
In ''[[Halo 3]]'', blisters were encountered in the [[Campaign]] levels [[Floodgate]] and [[Cortana (level)|Cortana]], and in the multiplayer maps [[Isolation]] and [[Cold Storage]], though the blisters in multiplayer maps do not release infection forms. Hitting the blisters with flame-based weaponry will cause the blister to burst, but not release infection forms. It could be possible that the infection forms that are supposed to emerge burst along with the blisters, but it happens so quickly that it looks like one simultaneous explosion.

In ''[[Halo Wars]]'', the Flood blisters are called Flood Eggs. Destroying these pods will sometimes reveal {{HWResources|[[resources]]}}, but other times, they will release either a swarm of infection forms or a Flood spore cloud, both of which can infect infantry squads in seconds.

In ''[[Halo Wars 2]]'', Flood blisters can be encountered in the ''Awakening the Nightmare'' campaign. They will detonate if any units get near them, releasing their payload of Pod infectors, but can also be destroyed from afar with weapons fire.

==Production notes==
*Flood architecture that release Flood enemies upon its destruction was conceived of as early as ''[[Halo 2]]''. In an early design document for the level [[Quarantine Zone]], there were references to a wall with "Flood crust" that contain [[Flood Juggernaut]]s, which would burst out of the crust or burst out from its debris if players destroy the crust. In the final release, these Flood crusts were replaced with either bottomless pits or a dead end; one would have blocked access to a tunnel that leads to the next area, forcing players to destroy the curst and release a Flood Juggernaut.{{Ref/Book|AoH|Page=142}} 
*In ''[[Halo 3]]'', the Flood blister was modeled by [[Bungie]] artist [[Vic DeLeon]]. Subsequently, it was nicknamed "Vic's boo-bag" by [[Chris Barrett]] and [[Paul Russel]].{{Ref/Reuse|vic}}
*Flood blisters were first named in the [[Phoenix Logs]] of ''[[Halo Wars 2: Awakening the Nightmare]]''. Prior to this, their only known name had come from Vic DeLeon's presentation on Flood environmental design in ''Halo 3'', where they were referred to as "Growth Pods".{{Ref/Reuse|bnet}}
