I know I'm a bit late with this, but it's still worth posting. After the DLC from the first Force Unleashed where Starkiller beats Luke and turns him to the dark side, I had a feeling we'd see these two die eventually. To see it actually happen was something else entirely though.
Seeing Princess Leia fighting Starkiller as a Jedi right after that was pretty cool. She puts up quite a fight. According to some of the expanded universe books Leia becomes a Jedi after Return of the Jedi so it isn't too far fetched. The ending shows a nice benefit of dual wielding. :P
