Star Wars: The Old Republic - Onslaught is the seventh Digital Expansion to Star Wars: The Old Republic. Onslaught introduces new quest areas in the new Onderon and Mek-Sha areas, as well as a new flashpoint on Corellia, and an operation on the jungle planet of Dxun. Subsequent updates brought a small expansion to the story, a brand new stronghold on the planet Alderaan and a new recurring event for swoop racing called the All Worlds Ultimate Swoop Rally. Even more was added later with a new annual event; The Feast of Prosperity, a cooking event, a servant droid mini-game, a new flashpoint named "The Spirit of Vengeance" exploring the Mandalorians' story, the main story quest titled "Echoes of Oblivion", and the flashpoint "Secrets of the Enclave". With a later update, old cutscenes from the base game Star Wars: The Old Republic were also revamped and improved, and new Login Rewards as well as Galactic Seasons were introduced.

War between the Galactic Republic and Sith Empire blazes across the galaxy. Crucial resources dwindle as piracy and crime escalate dramatically. Amid this chaos, the Alliance Commander has the chance to tip the scales in favor of either faction, committing their elite forces to decide the fate of the galaxy. As the Sith Empire prepares to make a decisive strike against a newly-constructed Republic shipyard on the planet Corellia, members of the Dark Council see victory on the horizon and begin plotting against one another in anticipation of the spoils. Meanwhile, Republic forces must race against time to muster reinforcements from across the galaxy in order to defend Corellia from the Sith. Pinnacles of Power Strengthen your ties with the Galactic Republic or Sith Empire and establish a new personal headquarters in the luxurious Alderaan Noble Estate!

As fighting intensifies across the galaxy, representatives from the Galactic Republic and Sith Empire arrive on Odessen to discuss plans of attack. Away from the war’s chaotic front lines, players can form a lavish base of operations within the Core Worlds by purchasing a new Stronghold: the Alderaan Noble Estate. For those wanting a more exhilarating experience, players can race at breakneck speeds during the All Worlds Ultimate Swoop Rally or take on the fearsome Master Mode difficulty of the Nature of Progress Operation.

The derelict ship carrying former Jedi Grand Master Satele Shan and her students has been found at last, far off its intended course. The Servants, fanatical agents of the former Sith Emperor, are somehow responsible – but their sinister plan is still a mystery. Meanwhile, the Mandalorian flagship Spirit of Vengeance II has been attacked by mysterious raiders. Shae Vizla plans an immediate counter-strike to drive these attackers away, but she’ll need powerful help to ensure the mission succeeds. The Dark Descent With the aid of some of your faction’s greatest fighters, visit the lost ruins of the Jedi Enclave on Dantooine in pursuit of one of the galaxy’s most formidable foes – Darth Malgus!

Away from the ruins of Dantooine, “The Stranger from Kubindi” is making its galactic debut! This is the first Galactic Season: a new way players can earn exciting rewards.
