The year is 2508. Since the advent of artificial intelligence in the mid-23rd century and due to humans' inability to keep themselves out of trouble, robots now control the world. Much of humanity has taken on robotic qualities. Control of genetic sequencing has enabled humans to be bred pre-specialized for certain tasks; clones can be harvested for personal use; bionetic modifications can serve to enhance human qualities.

Colonization of the moon is well under way (after several drawbacks due to human error.) Among the many agencies operating on the moon is GO GalactiCorps, which owns and operates GO Moonbase, consisting of two operational hubs: Shackleton Center, the primary lunar port, and Tranquility Island, the moon's most luxurious resort destination.

Several hundred human-operated stations and outposts occupy the areas surrounding these hubs, including solar panel grids, power relay stations, atmospheric vent housings, communication arrays, environmental sensor outposts, in/out mass driver ports and robotech factories.

Alone in a one-man outpost sits Hal Humbridge,
soon to be saviour of the human race.
