Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
it will be in the next update. As you can see, it has not a texture Nawrocki yet, I do not know if he goes to make it any time soon or late. But this and other models will be in the mod, there is not reason for do not add them and be improved with the past of the time.
