INFECTOR (DEAD SPACE)
Dead Space 1-3
The Infector is a unique Necromorph encountered in Dead Space and Dead Space 2. The Infector’s sole purpose is to spread the Necromorph contagion, thus creating more Necromorphs to spread the infestation.
Formed from a human torso and legs, its wings are formed by a flap of skin from the chest and then fused between the former host’s bent and broken legs. The jaw collapses within the body and the rest of the head breaks and twists into its proboscis and feelers and with the spine providing support and attachment points for articulation (movement). The proboscis, made from mutated bone, muscle, and spinal tissue is the delivery mechanism used to infect potential hosts. This is done by enveloping the host in its wings, extending the proboscis from the spinal cavity, and then stabbing it into the skull to inject a yellow fluid stored in an internal bladder. In any room with the remains of crew members, these are the beasts that should be taken down quickly before you get overrun with newly created Necromorphs.
They seem to have a preference for corpses which have existing head wounds, possibly because this spares them having to crack the skull themselves; the Infector in the Morgue goes straight for the captain, with his eye-to-brain needle puncture, over any of the other corpses, and Challus Mercer is seen to have “prepared” corpses for them by boring a hole in the center of their foreheads. These corpses seem to be most noticeable in the Crew Quarters on the Ishimura. Dr Mercer can also be seen killing Acting Chief Engineer Temple this way.
Infectors in Dead Space produce Enhanced Slashers (Unless the corpse being infected is that of a Marine, in which case the corpse will mutate into a Twitcher), while in Dead Space 2 “Enhanced” form of the Infectors will make Enhanced Slashers, and regular Infectors will make regular Slashers. It is implied that the Infector also creates the other single-body types of Necromorphs in the game, although only the creation of Slashers and Twitchers are witnessed in-game.
Enhanced Infectors are a very rare sight in Dead Space 2, appearing only twice throughout the Sprawl. They appear as slightly-darker Infectors.
