Infector
The Reanimating Necromorph
The Infector was a winged Necromorph whose sole purpose was to convert corpses into new Necromorphs, stabbing a proboscis into the skull to inject infectious tissue. Often the first form created by a Marker signal, it acted as an accelerant that spread an outbreak across a population of the dead.
The Infector was a unique Necromorph whose sole purpose was to convert corpses into new Necromorphs, multiplying the forms that spread an outbreak. Often among the first creatures created by a Marker signal, it acted as an accelerant, turning a room full of the dead into a host of fresh threats within minutes. For survivors such as Isaac Clarke, an Infector at work among intact bodies was a priority to destroy, since every corpse it reached became another Slasher to fight.
Anatomy#
The Infector was formed from a human torso and legs. Its wings were made from a flap of skin taken from the chest, fused between the host's bent and broken legs. The jaw collapsed within the body, while the rest of the head broke and twisted into a proboscis and feelers, with the spine providing support and the attachment points for their movement. The proboscis, built from mutated bone, muscle, and spinal tissue, was the delivery mechanism for the pure Necromorph tissue used to infect new hosts.
To reanimate a corpse, the Infector enveloped it in its wings, extended the proboscis from its spinal cavity, and stabbed it into the skull, injecting a yellow fluid stored in an internal bladder. The creature seemed to prefer corpses that already bore head wounds, possibly because this spared it the work of cracking the skull. Aboard the Ishimura, Unitologists were seen to have prepared their bodies for the creatures by boring a hole in the center of their foreheads.
Role in the outbreak#
The Infector existed to spread the infestation. It generally appeared in areas where many of the dead were gathered, such as the morgue aboard the Ishimura and the Church of Unitology on the Sprawl, and worked to turn those bodies into Necromorphs as quickly as possible. The forms it produced depended on the outbreak and on the host. In the events on Aegis VII, Infectors generally produced Enhanced Slashers, while the corpses of Marines became Twitchers. During the outbreak on the Sprawl, Enhanced Infectors made Enhanced Slashers and ordinary Infectors made ordinary Slashers. The form was understood to be capable of creating other single-body types of Necromorph, though only Slashers and Twitchers were observed being made.
Several accounts described those becoming Infectors aspirating a yellowish bile from their mouths as one of the first signs of the transformation. The creature was itself fragile, with few parts to sever beyond the infection proboscis, which was only revealed while it was at work on a corpse. If no bodies were nearby, an Infector behaved like any other Necromorph and attacked directly, and it would sometimes rest by sticking to walls or windows when it ran out of corpses to convert.
Variants and later forms#
A very rare Enhanced Infector appeared, recorded only twice throughout the Sprawl outbreak, distinguished only by a slightly darker coloration. By the time of the events on Tau Volantis, the Infector no longer appeared in its winged form at all, its role of reanimating the dead taken over by the crab-like Swarm Infectors that the Guardians there ejected to spread the infestation.

Guardian
The Guardian was a sessile Necromorph fused to the walls by the Corruption, unable to hunt but able to kill anything that drew near with a scythe-tipped tentacle. It spat embryonic Pods to keep threats at a distance and guarded the places most vital to the infestation.
Necromorph
Necromorphs were aggressive creatures formed when the Markers' electromagnetic signal reshaped dead tissue into monstrous new forms. Driven to kill the living and gather corpses for Convergence, they were the recurring plague that destroyed the Aegis VII colony, the USG Ishimura, and Titan Station.
Slasher
The Slasher was the most common form of Necromorph, reanimated from a single human corpse and named for the blade-like protrusions of bone that grew from its arms. Weak alone but lethal in numbers, it was the form survivors encountered most often in every major outbreak.
Twitcher
Twitchers were a fast and erratic variant of Slasher Necromorph created from hosts carrying Stasis Modules or adrenaline, whose reversed time dilation drove them to move far faster than any other strain. They were first encountered in the ruins of the USM Valor and recurred across the Sprawl and Tau Volantis.
Aegis VII
Aegis VII was a remote, metal-rich planet in the Cygnus system used by the Sovereign Colonies as a secret test site for Marker 3A. Two Necromorph outbreaks scarred the world, and after Isaac Clarke returned the Marker to its pedestal in 2508 the planet broke apart entirely.
Isaac Clarke
Isaac Clarke was a ship systems engineer for the Concordance Extraction Corporation who survived the Necromorph outbreak aboard the USG Ishimura, became a host for the Markers'' replication blueprints, and spent years hunted by EarthGov and the Church of Unitology as he fought to destroy the Markers.

Marker
Markers were enigmatic double-helix obelisks that broadcast a signal capable of reanimating the dead, driving the living to madness, and seeding their own replication. Their purpose was to spread the Necromorph infection across intelligent civilizations until a Convergence Event could form a Brethren Moon.
Oracle Program
