The Galactic Republic and Sith Empire are locked in open war. Resources are scarce, crime is spiking, and the Alliance Commander holds enough influence to tip the balance for either faction. In Onslaught, the Sith Empire targets a Republic shipyard on Corellia while Dark Council members begin scheming against each other in anticipation of victory. Republic forces race to get reinforcements there in time. Subsequent updates add civil war among the Mandalorian clans, the resurgence of Darth Malgus in the ruins of a Jedi Enclave on Dantooine, and the galaxy's first Galactic Season — a rewards track running alongside the main story with Fleet Apartment Strongholds, mounts, armor sets, weapons, and companions.
