Star Wars: Best of PC Cheats

There is a lightsaber in the RAS Prosecutor campaign, level: "Alone". When you get to one of the blocked areas where you have to breach it, turn around and try find a vent. Inside there is a dead trooper with a lightsaber suggesting he might have tried using it. You hear yourself saying something about "what you get" and "An elegant weapon for a more civilised time. Heh. Well... times have changed.".
