Murder Drones

Humanity drove itself into extinction ages ago when a mining operation at the Earth's core failed, causing massive damage to the planet. Service robots left by humanity try to eke out a new civilization, but killer robots developed by the mining corporation that caused the extinction event, following their programming to kill any rogue robots not following company protocols, massacre hundreds of service robots everyday. The story begins when a service bot finds an abandoned killer robot, who she plans to use to protect the service drone civilization.
