Additionally, the Markers' pulse can also imprint a self-replicating signal containing blueprints in the minds of suitable individuals, thus leading them to create Red Markers and spread the contagion.

This signal also affects the minds of any nearby intelligent life forms, usually manifesting in them as dementia, resulting in homicidal/suicidal actions, essentially setting the stage for the coming Necromorph infection. Necromorphs are structurally held together by the signal, and will degenerate into an "organic soup" in its absence.

These structures broadcast a highly concentrated electromagnetic signal that alters any dead tissue in range on a cellular level, converting it into pure Necromorph tissue and re-animating the corpse of the host organism. The generation of a Necromorph begins with the Markers. And the infector variant has provided a key insight: implanting the material directly into the brain renders optimal results." -Dr.

The resulting creatures are extremely aggressive and will attack any uninfected organism on sight. Necromorphs are mutated corpses reshaped into horrific new forms by a recombinant extraterrestrial infection derived from a genetic code etched into and transmitted by the Markers.
