Star Wars: The Old Republic: Onslaught represents the seventh digital expansion pack for Star Wars: The Old Republic, the MMORPG developed by BioWare. Its initial announcement occurred on April 13, 2019, during the Community Cantina Tour event in Chicago, Illinois, with its eventual launch on October 22, 2019.
The Sith Empire has turned its attention to the Republic's Meridian Complex Shipyard located on Corellia, amassing a substantial fleet under the command of Sith Lord Darth Malgus to ensure their triumph. Simultaneously, the Republic is formulating plans to bolster their defensive capabilities by procuring reinforcements from both Onderon and Mek-Sha. The Alliance Commander finds themself at the forefront as the renewed conflict commences.
Following the Battle of the Meridian Complex, both the Republic and the Empire have established specialized divisions, known as Task Force Nova and the Hand of the Empire respectively, to adapt to the shifting dynamics of the war. Concurrently, the Alliance Commander uncovers information regarding Darth Malgus's perplexing disappearance subsequent to the battle, confirming their gravest concerns that he has indeed become a renegade.
The location of the transport carrying Satele and her pupils has been discovered, prompting the Alliance Commander, alongside Kira Carsen and Scourge, to embark on a race against time to rescue their comrades before the schemes of the Sith Emperor come to fruition; however, they are confronted by both existing and newly converted adherents of the Emperor. Shae Vizla has been investigating unwarranted assaults on Mandalorian transports, and Jekiah Ordo proposes a risky strategy to lure the enigmatic force out of concealment, potentially at the cost of their lives.
Reports have surfaced indicating that the renegade Sith Lord Darth Malgus has been observed in proximity to the remains of the ancient Jedi Enclave on Dantooine! Consequently, both the Sith Empire and the Republic are mobilizing strike teams with the objective of intercepting Malgus before he can successfully execute his malevolent plans targeting both factions.
