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.
These three new stations will give you access to the advance units from ground and space. They will be unlocked by several ways, depending from your galactic conquest or the galactic conquest options.
These stations were release by Warb_Null few time ago. I have made some changes at lights and by this reason probably they look a bit different, of course as always I have added different hardpoints, shader and at two of them a complete death clone.
