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.
In the 7.1be. I have made a small but good change, I have changed the tech level from many ground units at skirmiss mode for the Empire. Perhaps you think how some of them are very advanced but you must see this point, the units from Force Unleashed 1 and 2 time era are before the Episode IV. By this reason, they can not be taken as units from tech level two or three.
