Story Mode
True Jedi: 20,000. This is pretty easy, but you will have to work for it a bit. Collect studs that are laying around and use the Force on some objects. No need to heed the individual bricks that you see along many of the edges. Aim to get around 10,000 before you enter the Archives area, but you'll be fine if you don't. In the archives there is a flat panel on the floor in front of the second alcove on the right is a power-up. Use this greatly to your advantage.
Characters: Obi-Wan Kenobi (Episode III), Yoda
Available for Purchase: Disguised Clone
Enemies: Disguised Clone, Clone (Episode III)
Temple Entrance
Move right and kill all of the Disguised Clones while you make your way to the large broken doors. Use the Force on one of them to move it out of the way so you can enter the temple.
Walkway
Head straight and kill the clones. Use the Force on the red pillar to make stairs against the wall. Go up the stairs and continue right. When you reach the end, use the Force on the 2 red small pillars to reveal a gear underneath each one. Use the Force on one of them, while the CPU takes care of the other one, to turn it. This opens up the wall to a new area.
Archives
Go straight into the more open area at the end. As you pass the alcoves, Clones will come out of each side, so take care of them. When you reach the open area, go right, and then into the 1st alcove. Use the Force on the wall panels to reveal platforms you can jump onto. Do this once more on a second set to reach the platform at the top, and use Force to activate the switch on said platform. Each time you activate a switch the floor panels in front of the alcove will light up. Go to the next alcove and do the same thing, except you will need to Force out a 3rd set of platforms to reach the very top button (jump first to the switch platform, then the third set of platforms, and then the button platform), which will disable the forcefield in front of the switch, giving you access to use the Force on it. Jump up to the third set of platforms relatively quickly, as they will go back into the wall after some time, unlike the other ones. Now, go to the 3rd alcove and do the same thing you did in the first one. After activating all 3 switches and walking back to the center, you will be shown the revealed entrance to the Display Room. Go inside it.
Display Room
More clones in here. However, if you're quick (and you already have True Jedi), you can avoid them all and go to the right wall and use the Force on the wheel in the wall to end the mission.
