On Vader's card, it has the above in the Card Title field below Vader's name. Obviously, Vader is unique, but what does the "x1" next to the Tie Advanced mean? I've looked throughout the rule booklet and even searched the forums to no avail. Had FFG even defined it?

Help me forum users! You my only hope.

Vaders tie was the TIE advanced x1 prototype, the x1 is not a game designation but a lucas arts designation. You can find more info by looking it up on wookieepedia but yeah dont worry its not something that effects the game. Its just that his ship was the prototype and has a slightly different designation.

Here you go: TIE Advanced x1

Cool! Thanks for the clarification guys!
