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.
Well, the last update from the mod with the Supremacy addition has been released. Now I will continue improving other things and perhaps adding some more because I would like the AT-AT from the First Order where clearly I need create one. Fortunatelly it is a normal AT-AT with some changes.
About all you. Probably you do not understand the Advance Construction Ship in the begining but it is not very difficult. Multiplayer GC can be a bit more strange. Anyway, both solutions are the unique possible for a mod with this amount of different units.
This is the Supremacy model made by T5UB4SA converted for my Star Wars Empire at War Forces of Corruption mod. You can know more about the creator here Deviantart.com
I hope warb releases his version soon, the model is done but he's yet to finish it up.
Good model but too skinny
