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.
I have not added new ground units for the clone wars, with more of 30 different companies with cis and republic, it is enough by the moment. But you can discover how the mod have many unique features as the advance command center which it can activate a special shield.
It looks just like they did back in Battlefront 2.. those were the good ol' days...
Coooool
