Each character gets specific abilities to deal with the puzzling challenges they'll face. Non-Jedi dudes like Han Solo will need to rely on special blaster techniques while the fur mountain Chewbacca can tear the limbs off of his opponents. Of course, the magic-enabled Jedi will still give you an array of Force powers for pushing around enemies and bits of the environment, but now each has their own unique moves like Vader's choking grasp or the Emperor's lightning shooting fingers.
An optional adaptive difficulty setting can interpret your skill level and scale challenges accordingly. It does this by making things harder on you with each success, so things never get too easy. Other minor adjustments to the pesky co-op camera allow a larger amount of the screen to be viewed while playing with friends ... silencing a nagging gripe from the original game.
