Story overview
The story of SteamWorld begins in a post-apocalyptic Earth, where human society has fallen into collapse. SteamWorld Tower Defense tells the story of a huge war between humans and robots for the control of Earth. After a long conflict, the robots prevented the human invasion and the surviving humans took refuge in the underground. Since then the bots began forming a civilization reminiscing the American Old West, with the upper classes composed of bots running on petrol, while the lower classes run on coal to survive. In SteamWorld Dig, a robot miner called Rusty inherits his uncle's mine and begins digging all the way to the ruins of an ancient race of electronic bots called the "Vectron", who is reactivated with his arrival. To prevent the Vectron from taking over the surface, Rusty defeats them, but disappears.

In SteamWorld Dig 2, a young robot girl called Dorothy who is Rusty's friend, looks for Rusty's whereabouts and discover that he was captured by the Humans, who intend to take control of the Vectron technology to reclaim the surface. However, the Vectron reactor in their possession overloads, causing a chain reaction that destroys Earth, with Rusty and Dorothy surviving by boarding one among several rockets created to evacuate the bots from the planet. The creation of one of these rockets is shown in SteamWorld Build, where a mysterious robot called Core guiding a bot population to settle near an old mine where they dig up parts of a rocket. Once the rocket is completed, Core reveals himself as part of the Vectron Hivemind who infiltrates the rocket's systems as they take the city's inhabitants to safety.
