The Star Wars: X-Wing 2nd Edition - Tantive IV expansion pack adds a CR90 Corellian Corvette to the X-Wing game world. In addition to the detailed, painted ship model, the set includes enough game materials to add the giant warship to two factions - either the Rebel Alliance or the Galactic Republic - including two ship cards, five upgrade cards and two maneuver wheels. Other components of the expansion allow players to fly this and other giant ships in combat. These include a special maneuver aid, as well as a scale for giant ships and a damage stack for giant ships.
