Infectors are Necromorphs that act as the fastest vector for the contagion, only attacking or defending when they cannot find any hosts to infect.
Infectors are bat-like Necromorphs that have a pale yellow skin and move around looking for dead bodies to infect. While they have wings they are not known to be able to fly very well, and are seen most of the time "hovering" above the ground. They are the second Necromorph ever recorded to be encountered, the first being the Wheezer. They do not really fly in the games but are shown to fly in the comics and films.
Regular guys just trying to create more Necromorph friends to play with.
- If an Infector contaminates a dead body with no arms it will create a Slasher that dies almost instantaneously.
- How there was a Wheezer before an Infector is unknown. But the most likely cause was the Marker's influence as it came from the water and the Marker was underwater.
