Instructions
Episode 4
Start Episode 4. The mission begins with you on a mountain ledge, jumping off into a tar pit.
Run left through the pit. Do not go straight toward the exit. Even though it's the more direct route, you'll miss an otherwise easy-to-get Red Brick.
Pick up the Red Brick. It's on the ground, on the far edge of the pit just before it curves back to the main path.
Episode 6
Play Episode 6. You'll start in a large hanger.
Turn both your characters into Jedi and have them stand on the platforms. Jump up to the next platform.
Enter the Stormtrooper's bunker. Step on each of the 10 switches inside. Once you've stepped on all of them, the Red Brick will appear.
