Can't get Darth vader to work properly
You need to be more specific. I don't know what the problem is without more information.
well, you need to buy to get THE SSD, and no if you play skirmish you can't use him.
That's the way it's supposed to be. If you mean land battle skirmishes, then hopefully that'll be fixed in the next patch.
yea vader is only avaliable in conquest, and he is something like 20,000 i think.
