+        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.
