Furnace expands into the twenties and thirties of the twentieth century -- the interwar period known as the interbellum. In this expansion, you will find new Company cards and Capitalists, new abilities, Manager tokens, variable Capital discs, a set of components for a fifth player, and new Agents for two-player and single-player games. All of this exists within beautiful industrial buildings and structures from the epoch of Art Deco, Constructivism, and Bauhaus. Base game required.
