I'm at a loss. How do you get the light saber master achievement? I am also stuck at 97.8 % I have all the Blue/white canisters. I have all the gold bricks. Every chapter is 100% complete. As is the bonus chapters and the bounty hunters ones as well. Dose it have something to do with the Arcade mode. I've only be in there enough to get the achievement. Do you have to win in every arena? Please help.

i'm also stuck in the same rut!! some one must post help for us!!

I don't know about lightsaber master. I'm kinda stuck there too but I believe what you might have to do to get a 100% is complete the super stories for each of the episodes. They don't give you any extras but from what i have read they do add to your percentage complete.

Preform 20 unblockable saber attacks.

to get 100% you have to each super story. each episode will get you 0.35% i think. its a lot of work. and the

lightsaber master achievement- press x then just as you finish that swing press x again then at the end of that swing press x again. each combo of 3 is one unblockable combo (the last hit is unblockable.) you can tell how because of the little stars that come out of your lightsaber if you are doing it right.
