Like its predecessor, The Force Unleashed II's engine uses Havok, Euphoria, and Digital Molecular Matter for motion and physics. The developers hope the story 'stands on its own' and will be enjoyable even by people who have not played the first game. LucasArts considered but decided against using a different protagonist for the sequel. Haden Blackman, who served as executive producer for the first Force Unleashed game, is also executive producer and writer for the sequel. Starkiller using Force lighting on Euphoria-encoded Stormtroopers Meanwhile, Darth Vader has produced elite clones of Starkiller to kill their template (Starkiller), destroy the Emperor, and defeat the Rebel Alliance. After eliminating his Stormtrooper captors, Starkiller embarks on a quest to understand his identity and to find his love interest from the first game, Juno Eclipse. Starkiller escapes from captivity on Kamino where Darth Vader has again betrayed him by placing him in shackles and ordering his execution. Players will control the clone of Starkiller, Darth Vader's secret apprentice and the protagonist thought to be killed in the first game.
The Force Unleashed II will be the 'dark entry' in the series, and a more personal story for the game's protagonist than the first game.
The game takes place about six months after the events of the first game, and a after A New Hope.
