Sadly, I kid you not. A couple of videos were released by IGN and featured in websites io9 and Slash Film that were UNTHINKABLE in the original movie trilogy, but are entirely possible now in the game universe of Star Wars: The Force Unleashed 2. In the expansion pack "Battle For Endor", your character (choosing the path of the Dark Side) will have the opportunity to fight AND kill Han, Chewbacca, and Leia - 3/4 of the main cast! Check out the videos and see for yourselves! SPOILERS though!

Now it's Leia's turn... and she's not going out without a fight... armed with a yellow lightsaber!
