Star Wars: The Force Unleashed is a multimedia project developed by LucasArts along with Dark Horse Comics, Lego, Hasbro, and Del Rey Books. It consists of a video game released in September 2008, a second video game released in October 2010, a tie-in novel, action figures, a comic book, a reference book, a role-playing game supplement, and a book on the making of the game.
Star Wars: The Force Unleashed tells the story of Darth Vader's secret apprentice, code-named "Starkiller" but born Galen Marek, as he hunts down the remaining Jedi after Emperor Palpatine orders them killed. Set between Star Wars: Episode III – Revenge of the Sith and Star Wars, the story explores the aftermath of the Great Jedi Purge as well as the rise of Darth Vader. The events of The Force Unleashed are "pivotal" in Darth Vader's history and development as a character and offer illumination into other characters from Star Wars, The Empire Strikes Back, and Return of the Jedi. Ultimately, Starkiller sacrifices his life to save the leaders of the new Rebel Alliance; they honor him by adopting his family's crest as their symbol.
