If you want to challenge yourself to the kind of winters that should really punish a dying world, then may we suggest HellFrost for your needs? With this mod, winters will become a much greater danger, impacting one of two effects over several different sets. Your armies will suffer attack penalties or their vision and movement will be dimished. Food management will become more difficult or approval will drop. Construction or science will be stifled by poor working conditions. Will you survive the winter or will you be lost in the blizzards of HellFrost?
