Play Chapter 1 of Episode IV: A New Hope. Destroy all of the little panels that a Force user can open. You can also go through the Bounty Hunter or Stormtrooper doors and use the Force on all of the little panels on the wall. Another way is to go through the door that can only be opened with a Sith (for example, as Darth Vader). Then, use the 2x Score Multiplier to your advantage.
