When you are playing Anakin in mission 16 stage or Obi-Wan in mission 17, there are six stages you must go through to complete either one. In stage one, Anakin or Obi-Wan is running towards you. Do not block yourself because you are going to stay still. Instead, go towards him and press Square as many times as possible. When he stands up, block yourself from his attacks. When you damage him enough you will go to the second stage. In there, hold Triangle when he is running towards you. If you are low in health, go to the other side of the table and heal. After becoming damaged enough, your opponent will go to stage three. In this stage, attack him as long as you can, then throw him to the boxes. When you are finished with all of the boxes, it should go to stage four. If not, attack until you enter stage four. In stage four, if you are low on health run away from him and heal. When you have enough health, start to attack him with fast attacks and throwing him into the boxes. If successful, you will enter stage five. Stage five is a long bridge, allowing you to jump over and attack him. Also, block yourself because your opponent will start using the Force or lightning. When he is not blocking himself, press R2 until he is confused. Use that moment to attack. Repeat the process until you enter stage six. In stage six, there is not enough space to run around. Attack your opponent. Use R2 to confuse and attack him. When he is low on health you have two options. Either hold Circle and stab him to end it easier, or attack him with Square until it is over. Note: Do not use Circle in the last stage if you are low on health.
