The Faro Plague, also referred to as the Faro Swarm, was the name given to the rogue swarm of Chariot war machines that caused the extinction of all life on Earth in Horizon Zero Dawn in the mid 21st century.
The Chariot line of peacekeeping robots was developed in the late 21st Century by Faro Automated Solutions under the direct oversight of the corporation's founder, owner and chairman, Ted Faro. Geared at the military market, the Chariot line utilized a concept of robots acting as a swarm, similar to an insect swarm. The robots were designed with formidable capabilities, such as the ability to exponentially replicate, consume biomass as fuel, and instantly hack and take control of any enemy automated military equipment such as drones.
