Frostpunk: The Board Game – Resources ExpansionThis set of plastic resources match other plastic components in scale. It simply enhances the overall impression you will get if you have the Miniatures expansion. Just like the play mat, this add on is purely of aesthetic nature and does not in any way influence the mechanics of the game. Also you have still to use the wooden coal pieces for the Generator. Contains: 8 Steel 10 Steam Core 20 Trees 30 Coal 30 Wood
