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.
I have added changes on the Empire attack to Yavin where now you can lose the Death Star.
This is small type of mission where I can put some special heroes from Rebel Alliance as the Red Squadron over Yavin when the Death Star attacks.
When i'm on Yavin i can't destroy the base it's normal?
