At any one time your character, for example, Princess Leia, will be accompanied by other stars of Star Wars, say C3PO and R2D2. At a click of a button, you can choose to control whichever of the main characters is alongside you at the time. Different characters have, naturally, different abilities; for example, Obi Wan can perform force powers such as lifting objects or stunning foes, whilst the robots are usually good for unlocking doors. Many puzzles in the game focus around using the right man for the right job and, more often than not, it's about how to get the right person in the right place to do that job.
