This is the final fight and is pretty tough under the Sith Master difficulty setting. First, keep blocking throughout the fight. Time your block with his lightning and create a counter. Once he gets some things to throw at you, jump up and use Force Repulse to get rid of them. Then, stand directly next to him and wait for his shield to come off. If he sends his guards at you, it is actually a good thing since are health for you. The only thing you must be cautious of is when you repeatedly hit him with your lightsaber. Sooner or later he will summon some debris to float above you, and the lightning that comes out will cause significant damage. Only do one or two full combos before jumping away. Continue deflecting his lightning back at him and you should be alright. You should make use of any and all tricks to defeat him. Throwing objects at him is not recommended unless you are very skilled, as he will probably hit you with his lightning before you can throw anything at him. Another great trick that takes some practice is to hit him with your own lightning and have a little spinning wheel come up. If timed correctly, you can get him every time in addition to the follow on attacks.
When you go into the room with all the glass chambers, one of the Imperial officers down below yells out "Project 1138 has escaped" or something similar. This is a reference to one of the first movies George Lucas made, which was titled 1138.
There is a catwalk above the main floor with a Health Drain power-up that will drain the health of everyone around you. Get up on the crashed Rebel ship's upper fin and jump up to the catwalk to get the Health Drain.
Once you defeat the first junk Titan you encounter, go across the bridge after this to fight more of those Force-controlled robots. Afterward, leap across a large area. Once there, to your left will be a section of steel beams. Force Push these down to find the Holocron that will give you the Sith robe.
Another easy way to earn Force points is to walk backwards through a level until you pass a checkpoint. Anything forward of the checkpoint will respawn. This works great on easier levels such as the first. Re-kill the enemies to gain more Force points.
Get through the second gate and go inside the room where you fight one of the Emperor's royal guards. In the room with the Wookie, on the wall to the left, is what appears to be Jar-Jar Bink, frozen in Carbonite, alongside other memorable characters from the Star Wars movies. The eye of the creature that was in the trash compactor with Luke and the little creature that sat next to Jabba the Hutt are also there.
During the first part of this battle, use Force Repulse or Force Shield with lightsaber attacks to take him down. When he runs into the room with hot red floors, pull an object off from the wall and hit him with it before he can attack you. After hitting him, Force Dash over to where he is and get some easy hits on him. Once he jumps on to the platform with you, use Force Repulse or Force Shield and maybe some Force Lightning. Try blocking as much as you can; if he hits you, he will do significant damage. Once he is close to being dead, press X to start the button sequence. After a short intermission sequence, you will have to battle him again--this time without his helmet. This battle is simple; just stay out of the air. He will try to use Force Grip on you if you are in the air and he isn't stunned. Use Force Dash to get away from him and use Force Repulse to break his block. Get a few hits in and he will not stand a chance. It will only take a couple Force Repulses to take him out, even under the Sith Master difficulty setting. Do the button sequence to defeat him.
Use the following strategy to defeat Kazdan Paratus under the Sith Master difficulty setting. The entire fight, keep him locked on so that you always face him. Keep Left or Right held while locked on and press [Dash] to do a flip to either side. If you press it while pressing Away, Starkiller will perform a backflip. Keep doing this throughout the fight. This will help with his Force Push. Once he starts a combo, flip to the side and start your own. Note: Do not do more than two moves unless you score a hit on the first slash, or else he will perform a combo himself. If you send a Sith Lightning at him, he will most likely raise his lightsaber and will pause a moment. This is your cue to flip to the side, as he will send it directly back at you. Keep moving throughout the fight. Once he climbs onto the pole, run to the left side and hide behind the broken wall closest to him. This should protect you from his object throwing. After he jumps off the pole, dash towards him. Do not get too far away from him or he will use his Force Push. This fight is one of the more challenging ones because he moves very fast and can use multiple Force Pushes or attacks, even if you are on the ground.
Make sure that you have your Force Shield up to level 1 or 2 before facing Maris (depending on the difficulty). When Maris turns invisible, charge up your Force Shield. If it is at level 2, the arcs of lightning will show where she is. Attack her while the electricity has her stunned. If it is not at level 2, try attacking randomly when she is invisible or use the Force Shield while she is still visible to get easy hits on her.
The apprentice's code name is "Starkiller", which is a reference to Bendak Starkiller in Star Wars: Knights of the Old Republic. Bendak was the Mandalorian who fought in the Taris arena near the beginning of the game.
An easy way to earn Force points is to reach a checkpoint located before a large group of enemies. Defeat most of the enemies, and intentionally die. When you respawn at the checkpoint your force point total will remain intact. Repeat as desired.
After reaching the point in the factory where the TIE Fighters attack you, there are metal beams you can bend. Bend the last one backward and make it a sort of step. Jump on the bent part and then again. Look at the roof of the hallway and jump there to find a clone trooper helmet on the ground.
After completing the first mission, pause the game and select "Input Code". Alternatively, complete the first mission and while on board your ship in between missions select "Extras" > "Enter Code". Activate the following cheats by entering the corresponding codes:
Note 1: Enabling this code will remove all of the lightsaber related Holocrons on the current saved game file.
On the final mission in the area of the Death Star where all of the green lasers meet, take the Graviton Generator up to its highest point. From here you can see the Holocron on the platform just above the highest laser. It is kind of difficult to reach. Use the Gravitron Generator to get as high as possible. When you are higher than the platform that the Holocron is on, press LB, B to get across.
Use the following strategy to get rid of the TIE Fighters when trying to pull the Star Destroyer out of the sky. The rocket engines are the preferred way of dealing with the TIEs by gripping them and throwing them at the fighters. However, a better way is to stand behind one of the pillars on either side of the platform (the left side recommended). Wait until the fighters fly by, heading off the screen, then do a double jump. Then, Force Lightning when they fly by. From there it is a matter of timing to know when to jump. This is a lot easier and does not reduce your health bar as much.
After electric bombing the initial entrance to the Hyperdrive Core three times, stand facing away from the entrance and walk slightly to the right. Look into the toxic waster sludge to automatically target something. Raise it up with Force Grip to see that it is an X-Wing.
In Raxus Prime after defeating the first junk Titan cross the bridge to fight more of the Force-controlled robots. Leap across a large area and force push the steel beams down. Collect the Holocron to unlock the Sith robe.
After you bend out the first mangled mess of metal and eliminate all the Rodians, stay to the right along the platforms as much as you can. When you reach the end just before the chasm, look over the edge to see Millennium Falcon.
The Rancor that you fight before Moris Blood under the Sith Master difficulty setting can be pretty tough if you use the same strategies you used for other difficulties. On Sith Master, as unfair as it may sound, you are far weaker and the enemy much stronger and clever. The Rancor will employ his main move; charging and stopping. After that, do not double jump and dash away as it simply takes too much time. Instead, stand your ground and at the last possible moment dash to the side. Do not use Power Dash as it will drain your power and put you too far from him. You must have to experiment with your timing. Dash too soon and he might follow you. If you dash too late, you will get caught in his attack and probably lose a lot of health, just because of the subsequent attacks. As for attacks, either jump to his head and perform a full combo, attack four times, or you can perform a single downward hit. Either way you are doing some damage. Do not engage Moris Blood as you will do absolutely no damage to her and will only get caught up in it and get hit by the Rancor. As for the Moris Blood fight, do not get too far away from her. Just keep attacking her. A three or four hit combo with lightning strikes works best (hit, lightning/hit, lightning/hit or hit, hit, lightning/hit, lightning/hit). There is no need for any fancy moves in this part of the fight--simply stay close and keep the pressure on.
Saving the game becomes disabled after entering a cheat code. To get around this, go to a checkpoint after entering a cheat code. Exit the game and at the main menu select "Continue". Then, press pause and select "Save".
To reset your health back to full at any time, (useful especially with Bosses), go into your Force upgrades, access your Force talents, and reset them. Then, go in and adjust all of them either back to your standards or as desired. Your health will recover when the game is resumed.
