Star Wars: The Old Republic, Bioware's Star Wars MMORPG, will get its first expansion in nearly three years this September, the dev team has announced. It's called Onslaught, it'll be free to all subscribers, and it will add a new story, two planets, a new Flashpoint, a new Operation and new abilities.

Onslaught's story "puts you at the center of the reignited war between the Galactic Republic and the Sith Empire," and you'll be given the choice of remaining loyal to your faction or sabotaging their war efforts.
