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.
The final development from the next version is at progress. I had liked release it this weekend but I need improve and specially test some new things more.
This image by example shows a new feature, a special ground commander with a new space/ground vehicle. There will be some similar for the Rebels and Black Sun.
There are many changes and improves, most of them only for the X version thought specially for Gold, Steam, GOG game versions. You can read more about it here Firefoxccmods.com There are many videos and information about the new changes.
Finally, just for the record, the next versions from my mod, all them will be as the X version. I do not go to continue working with the normal version and its special features which they do not run in the Gold, Steam and GOG. I do not see the point and clearly edit many different versions is a lot of tedious work.
