From the preview:
The TIE Advanced improves upon the TIE/In design by adding shielding, better weapons systems, curved solar panels, and a hyperdrive. However, the extra costs limit production, and only the best Imperial pilots get to fly a TIE Advanced.
The TIE Advanced Expansion Pack contains one sculpted TIE Advanced miniature, its maneuver dial, all requisite tokens, five upgrade cards, and four ship cards, including two Imperial aces: the aforementioned Darth Vader and the daring Maarek Stele.
