Story Mode
True Jedi: ~3,300. This is pretty easy. Just find 3 blue studs and you shouldn't have to try real hard for the rest. You can make it even easier if you grab the power-up on the near ledge from the original platform before going up the cliffs the second time as well.
Characters: Obi-wan Kenobi (Episode III), Commander Cody (NEW)
Available for Purchase: None
Enemies: General Grievous
This level takes place in one large area. Grievous has 10 hearts. Hit him once, and he will jump to the ledge to the left of another ledge that has a power-up on it. Switch to Cody to shoot the 2 bombs on either side of him. He will now jump back to the center platform with 8 hearts. Strike him 2 more times, and he will jump all the way to the top of a cliff in the middle of the map. Use the Force on the bricks that fell onto the platform after you shot the bomb to make a bridge to where Grievous was standing before. Jump/grapple up to the cliff area below Grievous. With the bricks near him, make a platform with the Force. Jump on the platform with Cody, and shoot the bomb next to Grievous. This will take away another heart, and send him back to the first platform. Go back, and strike him 3 more times, taking him down to only 3 hearts remaining, and sending him to a cliff off on the right. Go back to the first cliff he was at and build 2 steps with the Force to go up. You will see a bomb in a little cave to the left. Use the Force to bring it over to the other side where Grievous is, and shoot it. Grievous is now down to 2 hearts, and he will jump back to the original platform. Strike him twice more on the original platform to finish him and the level.
