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.
This is the new NarShadda ground map. If you have read about it, Narshadda is a poor version from Coruscant.
AWESOME! :D
When this is Nar Shaddaa I can't await to see Coruscant or Muunilinst. Mindblowing!
This is Coruscant. Moddb.com It was upgraded by me many time ago as other ground maps.
