Same mod, different name, The Galactic Empire, the Rebel Alliance, the Black Sun Pirates, and the Droid Empire, fight for control of the galaxy.
In order to make room for all the extra ships, I added this a Research ship, Nebulon for the Rebels, Victory Frigate for the Empire. I got the idea from Sci-fi at War, but is slightly different. You research upgrades and recurit heroes from here. The Starbase upgrade is still in the same spot just incase the AI doesn't build it, you'll still have a challange. The research ships also have less weapons and are slower that the other ships.
I suspose you can have only one of these?
Only one and only in skirmish.
