The game begins with the
Battle of Geonosis from
Episode II: Attack of the Clones. Jedi Masters
Mace Windu and Luminara Unduli lead a strike force of Jedi to weaken Separatist defenses and rescue
Anakin Skywalker and
Obi-Wan Kenobi. As Anakin and Obi-Wan are rescued, an army of Clone troopers arrive and battle the Separatist droid armies as Windu takes part in taking down key Separatist ships. Later on in the story, Anakin and Obi-Wan organize an evacuation of a Republic outpost on Rhen Var, leading the escape only minutes before the
Separatist Army captures the planet. One month after the Battle of Geonosis, the Republic detects unusual activity on Raxus Prime, and sends a strike force led by Anakin and Obi-Wan to investigate. On arrival, they find Separatist forces at an excavation site. They send for reinforcements to take the planet. The Republic captures Raxus Prime, but during the battle, Anakin is captured by Sith Lord
Count Dooku and bounty hunter Cydon Prax. Anakin is sent to Alaris Prime, a moon in the
Kashyyyk system, to be executed. Anakin and the other prisoners are doomed to be killed by the Force Harvester, an ancient
Sith weapon that drains the Force from all living things within its range. Anakin is able to escape his cell and uses a speeder to escape the Force Harvester's range. Anakin, with help from a female smuggler named Bera Kazan, infiltrates a Separatist communications outpost to contact the Republic for help. Then Anakin, Bera and the local Wookiee population hold off the Separatist forces until Republic reinforcements led by Obi-Wan arrive. Anakin and Obi-Wan then lead a counterattack against the Separatists and successfully liberate Alaris Prime. Anakin returns to the
Jedi Temple on Coruscant and informs Jedi Master
Yoda and Windu of the Harvester. Windu then tells Anakin and Obi-Wan of the Dark Reaper, an ancient
Sith weapon built during the
Great Sith War that was so powerful that none could withstand it. It required large amounts of energy to operate, which the Harvester could provide. Windu then mentions that the Reaper was destroyed by a fallen Jedi Knight named Ulic Qel-Droma, and the remains of the Sith weapon were scattered by the Jedi across the galaxy. To learn more about the Dark Reaper, Anakin and Obi-Wan lead Republic forces to Rhen Var, Qel-Droma's final resting place, to retake the planet from the Separatists. After a long battle, Anakin is led to an ancient tomb, where he meets Qel-Droma as a Force ghost, who agrees to teach Anakin how to defeat the Dark Reaper and reveal the location of the Sith weapon. Qel-Droma at the same time warns Anakin that this knowledge and power could lead him on the path to the Dark Side. With the Dark Reaper located on the ancient Sith world Thule, Anakin, Obi-Wan, and Windu lead Republic forces to Thule to prevent the Sith weapon from being rebuilt. Before the Republic can invade Thule, Anakin leads a strike force on the planet's moon to take out the planetary shield generator. Once on Thule, Obi-Wan and Windu lead Republic forces in eliminating Separatist defenses guarding the planet capital Kessiak, where the Sith Temple that holds the Dark Reaper is located. As the defenses fall, Republic forces enter Kessiak. While the Jedi and Republic forces battle the Separatists, Anakin enters the Sith Temple to destroy the Dark Reaper. Inside the temple, Anakin kills Cydon Prax and confronts the Dark Reaper, now operational. With guidance from Qel-Droma, Anakin is able to destroy the Dark Reaper and claim victory for the Republic on Thule. Obi-Wan acknowledges Anakin's growing power, but warns him to not let it consume him. As Republic forces are leaving Thule after the battle, Windu believes that the battle may have turned the tide of the war, but Yoda reminds him the war is far from over. ==Development==
