- 1). Start "Level 8: The Return" either through the "Level Select" menu or from the natural progression of the game.
- 2). Play through the level until you cross the broken bridge to reunite with Kota and then take the elevator up. Look for the lightning tower ahead of you. Lure the imperial forces to the tower.
- 3). Use your force lightning power on the lightning tower until the enemies around it are dead.
- 4). Jump over the ledge and kill the two AT-MPs. Follow the circular platform to a cluster of storm troopers. Do not kill these storm troopers.
- 5). Follow the path with the storm troopers in tow until you encounter another lightning tower. Take a few steps past it to lure even more storm troopers to your position. Wait for all storm troopers in the area to gather around the lightning tower.
- 6). Use force lightning on the lightning tower until all storm troopers are dead.
- 7). Jump off the edge to kill yourself to restart the section again if you have not yet earned the achievement. This will reset the section and let you kill more enemies with the lightning towers. Repeat the process until you kill 10 enemies.
