Trooper, Lancet Aerial Artillery, the TIE Defender, and the Super Star Destroyer Executor. Many of the new units and planets included in the game are incorporated from the Star Wars expanded universe. Plot The campaign story begins just prior to the Battle of Yavin; as the game progresses, events from the Star Wars films occur, such as the Battle of Endor. The tutorial mission sets up the main campaign plot, showing Tyber Zann's imprisonment for stealing a Sith artifact from Jabba the Hutt. The actual campaign story begins with Tyber Zann, the leader of the Zann Consortium, being rescued from imprisonment on Kessel with help from Urai Fen, his loyal friend and lieutenant of the mercenary army he built over the years; Fen himself arrived on Kessel with the help of Han Solo and Chewbacca. The four of them then escape aboard the Millennium Falcon. While re-establishing his headquarters, Tyber goes to Yavin IV after the Death Star destruction, where he learns of the Emperor's hidden treasury vaults and designs for a new Super Star Destroyer. After renewed conflict with Jabba the Hutt, Tyber sends Urai to capture Jabba's communications outpost on Saleucami and then goes to the factory world of Hypori, where he takes control of Jabba's Droideka factory, bribes the bounty hunter Bossk, and negotiates a truce with Jabba (both sides cease attacks, plus Jabba withdraws his bounty on Tyber and surrenders the planets Saleucami and Hypori). To unlock the secrets of the artifact, Tyber and Urai Fen go to Dathomir to find a dark-side Force user. They eventually free the witch Silri along with the other Nightsisters (both of whom are adept at the dark side of the Force). After killing the imperial governor, Tyber, Urai and Silri escape the planet and return to the Consortium's stronghold on Ryloth. Prince Xizor, the head of Black Sun crime syndicate, agrees to arrange a meeting between Tyber and an Imperial contact to sell the artifact. In return, Tyber is to steal some valuable Tibanna gas from the planet Bespin; with help from the bounty hunter IG-88, Tyber implicates the Black Sun, and watches Darth Vader finish them off. Later, Grand Admiral Thrawn and Tyber (in his new flagship, the Merciless) clash in space above Imperial planet Carida. During the battle, Bossk steals the artifact and heads towards Thrawn's ship, the Star Destroyer Admonitor. Thrawn retreats shortly after, however Tyber
