Story Mode
True Jedi: 60,000. May seem like a lot, but this is quite a long level so it doesn't end up being horrible. You don't have to go out of your way much, but do it once in a while. There is a purple stud in the Passage area which will help a lot. To get this, go to the second upper level of the area, and then to the left and go past the Droideka. In the hall past the droid is a structure that you can use the Force on to expel the stud.

Hangar
Go down the hall with Grievous at the end. He will send 6 Security Droids after you. Dispose of them, and then use the Force to blow up the door at the end of the hall.
Passage
Continue straight, trashing all of the droids, and then drop down to the lower level to destroy more droids. Once you get to the vertical tunnel, use the Force on the panels on each side to make platforms so you can use them to jump up to the upper level on this side. Kill the droids, and use the Force on one of the yellow grates to unblock the tunnels in which you need to go through. Don't forget to get the purple stud!
Elevator Room
After going through the tunnel, you will be greeted by a hoard of droids, including 2 Droidekas. After getting rid of them, the middle elevator door will open, revealing Artoo. Open the Artoo door for the right elevator, which reveals a blue and red container. Use the Force to move it into the next room, and use the Force again to blow it up, lowering down a platform which will take you into the next area.
Ventilation
Go right and avoid/destroy the 2 Battle Droids. Use the Force to make a platform from a gray panel on the wall. Jump up to it, and then jump up again to get to an orange switch. With the Force, turn the switch on, which will activate the fan, allowing Artoo to fly up and unlock the door that the Droideka is guarding.
Dooku Duel
Along with Dooku, there will also be a ton of droids shooting at you, including several Super Battle Droids. Dooku only has 6 hearts this time. Fight him basically normally, except when he shoots lightning at you (which he does after his 1st, 3rd, and 5th hearts are lost), where you just switch characters and strike him. After 2 hearts of his are lost, he jumps up to the balcony by the 2 Super Battle Droids. Grab the Power Up behind him, take 2 more of Dooku's hearts away, and he will jump back down. Do the same sequence (normal hit + hit after lightning) once more, minus the droids, and finally kill him after taking away 2 more hearts. After he is done for, Chancellor Palpatine will join you. His character does nothing besides run and jump. Go back up to the balcony, and then go straight through 2 open doors.
Elevator Shaft
This is suppose to mimic the scene in the movie where they are in the elevator shaft, and the elevator is coming down to hit them. In this case, the "elevator" is a giant block of metal chasing after you. If it runs into you, you die. Also avoid the holes on the floor as they are strong air vents that will push you up to the ceiling and kill you if you do not walk over them fast enough. Just stay tight to the screen left wall and you should be good. Once you get to the end, go through the tunnel on the screen left.
The Belly of the Ship
Here you will find a bunch of gears and vents and such in the first hall. The screen is also shaking, simulating the ship crashing. Continue along the path until you come across the steam jets. Use the Force on the wheel behind the jets to make the steam stop coming out so you can walk through. After that there will be more steam jets. To disable these, switch to Artoo, go through the steam, and activate the panel on the other side. Once that is done, use Jedi Slam to take down the gray panel on the wall so Artoo can use it as a ramp to get over the fallen pillar. Continue along the path until you reach the door at the end. Open it using the Artoo panel and go through.
The Bridge
First, take out 2 of Grievous's Bodyguards. They have pretty good melee skills, and it takes 3 hits to finish them off. When you get to the main bridge of the ship, a bountiful number of Security Droids will greet you. After taking them out, use the Force on one of the small orange levers within the controls while the CPU does the same to the other one. This will end the level.
