Lightsaber
In the assault ship level when you are making your way towards fixer, you will have to blow up two barracades that the trandos have put up. After making your way to the second barracade, don't blow it. Instead, look to your left (i think, if not jus twirl around) and you will see a small crawlspace. Go through, look to your right, listen to your character, and and see a lightsaber on the ground!!! Unfortunately, you can't pick it up. :'(
