The first CONTRABAND grew from a custom JavaScript project into Edge of the Fold. The current release uses JavaScript / Electron; its 3D presentation uses Three.js.
A browser origin, a Steam release
Earlier development notes described the browser build and its lightweight origins. That public edition has been retired. Those historical size figures and browser instructions do not describe the current Steam release.

A separate foundation for the sequel
Beyond the Fold is being developed in Godot. Its new foundation does not change the first game’s history or make its features promises for the sequel.
