        Factorio is a game in which you build and maintain factories.

        You will be mining resources, researching technologies, building
        infrastructure, automating production and fighting enemies. Use your
        imagination to design your factory, combine simple elements into
        ingenious structures, apply management skills to keep it working and
        finally protect it from the creatures who don't really like you.

        Factorio has been in development since spring of 2012 and it is
        currently in late alpha.
