Shadow of the Sith was a proposed video game concept by W. Haden Blackman for development at the video game studio LucasArts. It would have featured Sith far in the future compared to the time period of the main Star Wars franchise. Work on the game halted as Blackman's focus shifted to the video game Star Wars: The Force Unleashed II.
Development on Shadow of the Sith began at LucasArts in 2008 after the video game Star Wars: The Force Unleashed began to reach the end of its development cycle. W. Haden Blackman had previously pitched a project in 2004 titled Star Wars Episode VII: Shadows of the Sith, focusing on the character of Ben Skywalker. While the project ultimately did not move forward, Blackman repurposed loose elements, including part of the title, into Shadow of the Sith in 2008. The game would have featured Sith far in the future compared to the time period of the main Star Wars franchise.
Ultimately, work on Shadow of the Sith halted and Blackman shifted his focus to Star Wars: The Force Unleashed II. The concept of a "far-future" Sith video game would later be included in the similarly canceled Battle of the Sith Lords, a project in development at Red Fly Studio under the guidance of LucasArts.
