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.
Coming from a Evillejedi better design for a canon starship but never released to the public, I have edited the previous Defender Star Destroyer for to make the Endurance Star Destroyer.
The skin was made by Nawrocki editing the Evillejedi´s texture.
