Welcome to the frontier.

Welcome to the home of Tool Progression: Stone to Electric - a RimWorld mod about the long journey from a rough tool to a capable, powered colony.

Explore the homepage’s era selector and searchable system cards for an overview of the project. The field guide provides a practical starting point, and the release center will hold published builds and their notes.

This site is also a home for useful testing feedback. The private report form helps the team collect reproducible issues without publishing personal details.
