From the Author:
This is the sitwars SP mod for JKII. It replaces kyle with Darth Vader, Luke with the emperor, Jedi with sith and Reborn with jedi. It also changes the lightsabercolors and sounds.
This mod reverses the force sides in SP. This time YOU are of the dark side against the light side. The mod is little weird because you can still hear Kyle's voice and everything, but whatever was possible to change was changed (like sabers, sound effects, etc.).Unzip all 3 pk3's to your base folder to make this mod work.
