There are two campaigns; Forces of Darkness and Namelesennian Security Forces, much like the Galactic Empire and the Rebel Alliance in the original Empire at War. The Darkness campaign starts with the Raid on the Sith Temple and leads up to the destruction of the city Namelesennia, during Darth Kaxs quest to gain a foothold in the Namelesennia system. The NSF campaign focuses on Namel Es's' quest to protect the people of the Namelesennia. Also the NSF campaign leads to the destruction of Namelesennia, but starts with the Battle over En'rg-ch.
