The Force Unleashed casts players as Darth Vader's "Secret Apprentice" and promises to unveil new revelations about the Star Wars galaxy. The game's expansive story is set during the largely unexplored era between Star Wars: Episode III Revenge of the Sith and Star Wars: Episode IV A New Hope. In it, players will assist the iconic villain in his quest to rid the universe of Jedi – and face decisions that could change the course of their destiny.

The Wii version, in development by Krome Studios, will also add an exclusive duel mode in which players can compete head-to-head with their friends to determine the ultimate Jedi Master.
