For this little piece of eye candy you need to beat the game on any level of Difficulty with all of the challenge points to get the Leebo Scanner. When you go to a Boss, right before entering the Boss arena click on your Scanner by holding the camera switch button for 5 seconds.

Walk into the Boss arena and it will start the video but from DASH'S point of view. Ex. When you fight the AT-ST at the Echo Base you come down the hall and as soon as you get to the door the movie starts and the camera goes behind the AT-ST's head and shows him look around then start walking and then the cam goes back to your view.

WITH the Leebo scanner on it will just click off your scanner and show the movie like before BUT you will see it from YOUR point of view. This will work on any Boss that plays a movie before the fight. (Just be sure you have the scanner on before the movie starts.)
