A long time ago, in a galaxy far far away, there lived a Jedi. That Jedi was to bring balance to the Force, and, in some ways, did so by returning to power the feared Sith, the enemies of the Jedi. That Jedi, who would become Darth Vader, would serve under Darth Sidious. Ancient Sith lore told that there would only be two Sith, a master and apprentice. That is, until now.
Star Wars: The Force Unleashed, developed and published by Lucasarts, aims to tell the story between Episodes III and IV; the story of the rise of Darth Vader, the aftermath Great Jedi Purge, and the birth of the Rebellion.
