+      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.
