Spore carrier

Spore carriers are creatures that inhabit the Mojave Wasteland, as well as Zion Canyon and Big MT in 2281.

Background
Spore carriers are humans who had been exposed to the entomopathogenic fungus Beauveria mordicana.

Beauveria mordicana was developed before the Great War in the Big MT research facility X-22 botanical garden to colonize the bodies of common pests. It was delivered to Vault 22 as a part of the Vault Behavioral Project. A report in the medical wing of Vault 22 states that the host technically dies once the fungus has fully colonized the host body, but the fungal colonies continue to animate the body. In this manner, the fungus moves amongst more of its prey, occasionally spraying spores in a radius around the host body and infecting all who come near it. The drawbacks of Beauveria mordicana include the long time required to kill prey (10–20 days), and the limited effectiveness against nonsocial pests.

The inhabitants of Vault 22 were exposed to Beauveria mordicana, and those of them who left the vault have spread the fungus as far as Zion Canyon, where spore carriers pose a problem even in 2281. It seems that the spread of the green fungus happens over time, as the doctor who first performed an autopsy noticed nothing wrong externally with the first infected victim. Upon autopsy, it was discovered the fungus had manifested throughout the lungs, explaining the carrier's nasty coughs (noted both in the Vault 22 and the Zion terminal entries) before they succumbed to the fungus.

The first spore carrier made was presumably Patient Zero at Big MT, while Harrison Peters was the first infected in Vault 22.

Gameplay attributes
Spore carriers are quick and use melee attacks. Spore carriers share some characteristics with the trogs from the Fallout 3 add-on The Pitt. If they are not killed quickly, they explode and deal large amounts of damage, breaking limbs, and giving a large dose of radiation. When they are hiding in vegetation, they are hard to spot and will not appear on the Courier's compass, nor be targeted via V.A.T.S. until they move.

Walking past unexplored vegetation can result in an unpleasant scare. Spore carriers are also known for sneaking up on their victim. However, their health meter will become visible if they are injured by an area-of-effect weapon, like a flamer or grenade, immediately revealing their presence.

Upon detecting an intruder, the spore carrier will raise themselves out of the large patch of vegetation where they hide, and will let off a growl in a similar manner to that of a feral ghoul, but with greater ferocity.

While a spore carrier is getting up or sleeping, attackers in sneak mode who manually attack the spore carrier will get a critical. Combined with a decently powerful weapon, such preemptive strikes can often kill the spore carrier before it can cause any harm.

Spore carrier
The most common of all spore carriers. They hide in vegetation and attack anyone tripping over them.

Spore carrier brute
Spore carrier brutes are found in the same areas other spore carriers are found, and usually tend to act the same. However, brutes tend to be more aggressive, and are tougher and larger than regular spore carriers. A brute's spore burst does equal damage to a regular spore carrier.

Spore carrier runt
Runts are the smallest and weakest of the spore carrier family. However, they are still quite fast and may overwhelm an unaware, low leveled character. Also, a runt's spore burst is equally as damaging as a regular variant's.

Spore carrier savage
Savages are encountered rarely, but are essentially a more dangerous form of spore carrier brutes. A savage's spore burst is equal to that of the regular version.

Spore carrier beast (Honest Hearts)
The spore carrier beast is only found in Zion Canyon in the Honest Hearts add-on. They are stronger than any of the other spore carriers, and are often found around spore plants.

Spore carrier scavenger (Old World Blues)
This variant of spore carrier appears only in the Old World Blues add-on at the X-22 botanical garden.
