SteamWorld Build

Set during the events of SteamWorld Dig 2, with the planet's destruction imminent, Jack Clutchsprocket arrives at an abandoned mine along his daughter Astrid and a group of refugees. They are guided by the mysterious bot "Core", who told them that inside the mine are the materials they need to assemble a rocket they can use to escape the planet. Just after settling their base, they are approached by an old, battered bot called "Trader", who assists them in their mission.
As they gather parts to build the rocket, Astrid is contacted by the Ancient Signal that controls the machinery there, warning her about an imminent danger, when the rocket is completed, Core reveals himself as part of the Vectron Hivemind, who deceived the bots into build the rocket so they can escape the planet. Pursued by the Vectron machines, Trader stays behind, sacrificing himself to allow the others to escape the planet. Once in space, the bots depart to look for a new home to settle, unaware that the Vectron Hivemind has infiltrated their systems.
