Drones are the Chimera's robotic and unmanned flying units, first seen in Resistance 2, but appear earlier in the storyline, appearing in Resistance: Retribution and Resistance: Burning Skies. It appears that the Chimera abandoned the usage of Mines and replaced them with Drones. Much like the Chimera, Drones have multiple yellow eyes-possibly used for purely aesthetic reasons, since the Drones could easily function with just one. Another possibility is that the machines use the multiple eyes to allow thermal imaging or night vision.
