Ten years before
Attack of the Clones and shortly after the
Battle of Naboo, the
Sith Lord
Darth Sidious orders his apprentice,
Darth Tyranus, to eliminate his former pupil-turned-
Dark Jedi and current leader of the Bando Gora crime syndicate, Komari Vosa, before she becomes a threat to his future plans. Meanwhile,
Jango Fett captures gangster Meeko Ghintee after a long pursuit on the Outland Station, and turns him in for the bounty on his head. Upon returning to his
Toydarian friend Rozatta, he is contracted by Tyranus with killing Vosa for 5,000,000
Republic credits. To find Vosa, Jango investigates the Bando Gora's distribution ring of addictive "death sticks" and captures death stick dealer Jervis Gloom on
Coruscant, who reveals his source to be a gangster named Groff Haugg. While investigating Haugg's processing plant, Jango runs into his longtime rival, Montross, who is also hunting Vosa and has killed Haugg via
carbonite freezing after interrogating him for Vosa's whereabouts. Following a brief fight, Montross leaves to find Vosa, while Jango infiltrates the penthouse of
Twi'lek Senator Connus Trell, who is also involved in the death stick trafficking ring. Trell tells Jango to seek the Dug crime lord Sebolto on
Malastare before being thrown to his death. After escaping from a Republic gunship, Jango learns that Sebolto has put a 50,000 credits bounty on the head of his former employee Bendix Fust, who is incarcerated at the asteroid prison Oovo IV. Believing that capturing Fust will allow him to get close to Sebolto, Jango infiltrates the prison, but finds that another bounty hunter,
Zam Wesell, has beaten him to Fust. The two are forced to work together to escape from Oovo IV with Fust, and stage a riot to create a distraction. After Jango's beloved ship, ''Jaster's Legacy
, is destroyed, he, Wesell, and Fust escape in another vessel, which Jango dubs Slave I''. Meanwhile, Montross finds that Haugg gave him a false lead, but hears of the Oovo IV riot and, realizing it was Jango's doing, decides to follow him. Jango delivers Fust to Sebolto on Malastare, but the crime lord quickly deduces Jango's true intentions and attempts to flee, only to fall to his death down a pipe leading into his death stick factory. Jango enters the factory and finds some Bando Gora members guarding a ship with
Huttese markings on it, hinting at the
Hutts' involvement in the death stick distribution ring. Montross ambushes Jango again, taunting him over his adoptive father's, Jaster Mereel, death, and the disastrous Battle of Galidraan, where Jango's
Mandalorian forces were slain by a
Jedi ambush. Jango is defeated, but escapes with Wesell's help. On
Tatooine, while Wesell goes to question
Gardulla the Hutt, Jango impresses
Jabba by killing Longo Two-Guns and his gang. After learning from Jabba about Gardulla's involvement with the Bando Gora, Jango travels to her castle, but is captured after an imprisoned Wesell, whom he left in her cell to avoid sounding the alarm, compromises his position. Quickly escaping, he confronts Gardulla and feeds her to her pet
Krayt dragon, which he then kills. Leaving Wesell behind, Jango continues his search for Vosa alone, only for Montross to attack Rozatta's station in an attempt to hinder him. Jango arrives to find a dying Rozatta, who gives him a guidance device to help him track Vosa and asks him to find something to live for besides money. Jango journeys to Bogden's moon Kohlma, the Bando Gora's secret headquarters, where he finds Montross waiting for him in front of Vosa's citadel. Jango defeats Montross and leaves him to be killed by the Bando Gora, refusing to give him a warrior's death. As he enters the citadel, Jango is captured and tortured by Vosa, until Wesell suddenly arrives to rescue him, getting herself injured in the process. After finally defeating Vosa, Darth Tyranus arrives and chokes her to death, before explaining to a stunned Jango that the bounty was merely a test to find someone worthy of becoming the genetic template for a
clone army, and that Jango passed it. The bounty hunter agrees to be cloned but, in addition to his monetary reward, demands that he get to keep
one unmodified clone for himself (thus honoring Rozatta's final wish). The game ends with Jango carrying the wounded Wesell to
Slave I, while telling her not to push her luck when she asks to split the reward 50/50. ==Development and release==
