Star Wars: The Force Unleashed heavily involves the Force. Like Star Wars Episode III: Revenge of the Sith, the Force and lightsabers are the only weapons you will use in the entire game. In the campaign you will take control of Darth Vader's secret apprentice, StarKiller. You will be in charge of committing Jedi Genocides and completing Order 66. You are the Dark Jedi StarKiller and you will use force lightning and other dark powers. In the first mission you will take control of Vader, who finds a child and makes him his secret apprentice.
This game takes placed after the Clone Wars has ended. It's worth noting that there's three versions to this game. The DS and PSP versions have been remade to fit the requirements of their systems. The Xbox 360 and PS3 versions have very large environments and has tons of items to use. The PS2 and Wii are different in that the levels are not very big but it's easy to navigate. Also for the Wii, you get to use your Wii remote as a sword.
