Seventy-eight years after the Great Collapse, the city of Belmarc stands as a beacon of civilization amid the ruins. A city where magic and technology intertwine, where humans and machines coexist. And in its depths, one Courier begins to chase the forgotten sins of the past.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.
