in tatuine go to a sandstone house thing that has stairs leading up to the roof and a purple tarp thing and go in the small place in between them and you will start shaking and you may loose health, but after a while you will suddenly appear inside the house. you can shoot the people outside, but they can't shoot you. you can walk out of the house through the walls, but then you have to go back in with the stairs and the tarp.
