The clock is ticking for planet Earth and the race is on to find a new world capable of sustaining human life. New, sophisticated machine lifeforms called Astrobots are dispatched to scout far-flung worlds in the hope of crafting a new home. With food and raw materials running out and climate disasters escalating, the evacuation of the entire human population is the only slender hope remaining.

On Colony World 1, a catastrophic power struggle forges a new - all-Astrobot - society, and presiding over this nascent civilization is Atlas, an evolved mech with a futureproof plan. A plan that does not include humankind.
