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 TIE Silencer with a complete improved skin from Nawrocki. In the mod, it will be the ship from Rylo and a special expensive fighter. You will be able to build squadrons from this unit, probably this week because I go to add it today.
