In mission one of the Wookie campaign you can get queen Amidabla. All you have to do is go to the east of the level. You should see Tusken Raiders and different buildings. As soon as you get there the buildings will become yours and you will get queen Amidabla.
NOTE: I found the easiest way to do this is to first put the "forceexplore" code in, then scroll over to the section and type "simonsays". This way you will have guys there instantly. After you get the queen she cant die or else you fail the mission.
