As you can see in the clip here, Darth Vader will be a playable character in Star Wars: Force Unleashed, specifically in the first mission. Available to you will be an abundance of Sith force powers, including Darth’s favorite, the force choke. The mission’s purpose is finding Darth’s secret apprentice (who you play as in the game) on the wookie home world. So, Star Wars fanboys rejoice, more Vader awesomeness is on the way. Who wants to choke a wookie? (I do!)
