The expansion adds two major story arcs set during the events of Attack of the Clones :
: Focuses on Darth Vader immediately after the Battle of Yavin. The campaign follows the Empire’s hunt for the Rebels, leading up to the Battle of Hoth and the occupation of Bespin.
: Focuses on Jedi Master Echuu Shen-Jon (the same character from the Rebel campaign) as he leads clone troopers to stop Sev'rance Tann and recover the Decimators, ultimately leading to a personal tragedy that explains his later exile. Where to Play
: Follows Count Dooku's apprentice, Sev'rance Tann , as she attempts to secure "Decimator" technology to cripple the Republic's power supply.
