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.
Thanks to Darkgrazi from Alpha Blue by telling me where I could find the example of code, I could add some pieces from the old EAW campaign to some galactic conflicts. With them now when the Death Star is builded, it can destroy Alderaan. Other improves are the destruction from Byss by the Eclipse SSD MKII from the Emperor and the destruction from Carida by the Sun Crusher. All them very important for the history of GC. Have fun.
So.. you can only blow those up?
I thought this game was about making your own history :D
Or do I misunderstand? No offence btw, great mod.
There are many and different GC, each of them with different features. On Birth of the Rebellion, all sides start with very few planets and you make your own choices. But by default Alderaan is always destroyed when Death Star is builded. There is nothing strange on it if you play with Rebels.
After Alderaan is destroyed, Death Star will attack you on Yavin and you must defend yourself. Have fun.
Wicked cool!
