When playing Assault in Mos Eisley, choose any Jedi or Sith with force jump. then jump onto the roof of the Cantina (CP4). Move backwards until you are directly above the door facing the rocket. Take one step forward and start swinging; then, move backwards until you nearly fall off of the roof. Walk forward and you should be inside the roof. If you swing your Lightsaber again, you should fall into a fairly large room. P.S. This glitch is tricky to pull off; you probably won't get it on the first try.
