Special power-ups - Some special power-ups are hidden in objects and environments; hit them with the lightsaber and they will appear.

Running - To run left, press Left(2). To run right, press Right(2).

Defeating Jedis - When fighting a Jedi, wait for his special attack then block it (press L). After this is done, attack him as hard you can.

Defeating bodyguards with Anakin - In Anakin's story mode in the Utapau System, instead of fighting all of the bodyguards with staffs, ignore the yellow ones and take out the red ones; this will cause the others to retreat.
