Very quick Outcast/Criminal faction fix.
Head off to the Hokkidio sector from New Toyko. As you gate in, you'll see Sapphiro station dead in front of you. Head toward the station, and you'll see a tradelane under construction heading off toward the east. Past it, will be a long series of navigation satellites and several more tradelanes being built, extending counterclockwise around the sun to the top center of the map. Along the way you'll see a number od Deep Space Engineering supply depots, filled with construction machinary. If you blow up these depots, you'll recieve a huge boost to all your criminal factions, as well as Outcasts. If you watch your factions carefully, and blow up about 5 depots, you'll find that you will go neutral with everyone except the Unioners and Mollys, and of course, you'll go hostile with DSE. From there, it's a much simpler task to correct whatever factions you need to.
