Runners are nicknamed after a mysterious type mech disguised as humans, often seen fleeing from ships and bases that have been attacked or damaged. In order to avoid capture they will run and often escape by any means. Several have been known to open airlocks and jettison themselves or jump into a reactor stream to meltdown. They are often seen carrying out sabotage attacks by any way possible including tampering with safety controls for weapons, reactors, and environmental systems. Just as mysterious, when caught before self-destructing, they have no means of communication or capability to transmit any messages. No one knows who or what has programmed Runners or how to stop them.
