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.
With the help of Hyuza, I have added a new galactic map bases on the Star Wars Atlas and where you will see a bigger galaxy with divisions for each sector (deep core, core, colonies, inner rim, expansion region, mid rim and unknow region).
The strange image were you can see all the planets is only as a example where I added a bigger zoom.
