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.
Another new model added thanks to Warhammer_81. It will be the special constructor unit from Black Sun. This model with a different color is shared with the Rebel Alliance. Curiously I have problems finding new units from this time era which I have not used before in the mod.;)
You can see these units in battles but the main purpuse from this constructor ship is trigger the build from some structures in galactic mode. It is the unique good mode which it will not affect a lot the game performance where I can add special units for multiplayer. Always without forget how with the previous normal mode, there is not way where you can build everything. It is a big problem showed with many mods and because this mod is my big baby, I want make it better and different without these problems.
