Star Wars: The Force Unleashed casts players as Darth Vader's "Secret Apprentice" and promises to unveil new revelations about the Star Wars galaxy. The expansive story, created under direction from George Lucas, 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.

Allegedly, the game is to give players Force powers in four basic categories: grip (which lets you telekinetically manipulate objects or enemies), push, lightning and repulse (a 360-degree Force push all around the player). These powers develop over the course of the game through usage.

As its name implies, The Force Unleashed completely re-imagines the scope and scale of the Force by taking full advantage of newly developed technologies that will be seen and experienced for the first time: Digital Molecular Matter (DMM), by Pixelux Entertainment, and euphoria by NaturalMotion Ltd. Paired with the powerful Havok Physics system, these new technologies create gameplay only possible on the new generation of consoles. DMM incorporates the physical properties of anything in the environment so that everything reacts exactly like it should - wood breaks like wood, glass shatters like glass, plants on the planet Felucia bend like plants on the planet Felucia would, and more.
