Las Plagas Infection

A parasitic nightmare turning a peaceful Spanish village into a hive of mindless, obedient killers.

The Las Plagas infection is a parasitic biological weapon originally discovered by the cult organization Los Iluminados centuries ago, with Osmund Saddler serving as the current cult leader who unleashed the parasites upon an unnamed village in Spain. Unlike the viral pathogens seen elsewhere in the franchise, this specific strain consists of small, insect-like parasites (often resembling ticks or beetles) that attach to the host's spine to control motor functions and amplify aggression. It represents a dark evolution of bioweaponry designed not just to kill, but to create an obedient, hive-minded workforce under the command of a single master.

Origin
Los Iluminados (discovered centuries ago; unleashed under Osmund Saddler)

Lore & Background

Infection typically occurs through ingestion of food or water contaminated with Plaga eggs. Once inside, it rapidly matures, altering the host's physiology to enhance strength and durability while stripping away free will. The village in Spain became a testing ground where the entire population was secretly infected, turning neighbors into monsters who worshipped their leader as a god-like figure. This forced loyalty made the outbreak particularly difficult to combat, as the infected would not scatter or flee but instead attacked with singular purpose.

In Their Own Story

The torchlight flickered against the stone walls of the village square, casting long, dancing shadows that seemed to reach out. A low, guttural chant rose from the crowd, a sound that was less human and more like the grinding of stones beneath a boot. The villager before you did not blink; their eyes were clouded with a milky haze, yet they held a scythe with terrifying precision. When the leader spoke, it wasn't with words but a psychic command that rippled through the air, and instantly, every head in the square turned in unison toward the intruder.

Reader's Guide

The story begins when a lone operative is dropped into the Spanish village of Castille del Sol to rescue a captured presidential daughter. Upon arrival, they discover the entire population has been transformed by an unknown pathogen. The villagers act with unnatural coordination, attacking on command and displaying enhanced physical capabilities. As the operative fights through the village and surrounding farmhouses, they encounter various specialized infected forms, including those who wield weapons or possess unique abilities. The investigation reveals that a rogue faction of Neo-Umbrella is running the operation from the local church, led by a charismatic cult leader who has been infected with a superior strain. This leader uses the parasite to maintain absolute control over the village and plans to distribute the infection globally via a shipment of biological samples. The operative must navigate traps, fight through hordes of mind-controlled citizens, and confront specialized bio-organic weapons created from mutated humans. Ultimately, the protagonist breaches the church, defeats the cult leader in a brutal confrontation, and destroys the primary source of the parasite's control. With the leader dead, the hive mind collapses, leaving the remaining villagers as confused, dying husks. The facility is destroyed to prevent further spread, marking the end of the immediate threat, though the existence of such a weapon leaves lingering questions about the safety of the world.
