Instructions
Find some power bricks by using certain classes of characters in levels. For example, pick a bounty hunter such as Boba Fett in the level "Invasion of Naboo." After going past a series of sinking stones, you will see a green circle picturing a bounty hunter. Open a panel here with Boba Fett to get the power brick.
Use the Force. Jedi characters can help you get some of the power bricks, such as the one in the "Retake Theed Palace" mission. Push the chairs and tables together in the dining area using the Force. Smash a statue in the back of the room and step on a button that appears. This will open an area with plates and cups. Use the Force to push these into the pile you've created. Blow it up with your lightsaber or other weapon to make the power brick appear.
Find power bricks in vehicular levels. In "Bounty Hunter Pursuit," you must pilot a TIE Fighter through the level. Turn right after passing the first force field. Quickly shoot all of the pylons with the green lights left of the Imperial gate to make a power brick appear.
Assemble items to earn other bricks. In "Mos Eisley Spaceport," you can use the Force to remove the lids of four garbage cans near the beginning of the level. Use the Force a second time to remove the contents of the cans. Build a door with these parts to enter a room with a power brick.
Buy the power brick detector to make the hunting easier. This is obtained by getting the fourth power brick in the game in "Mos Espa Pod Race," which you can find along the course. Head to the cantina from the game menu and spend 125,000 studs to buy the detector. Now when you go through a level you will see flashing arrows pointing toward the bricks or objects you need to use to get to the bricks.
