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.
Some news here. You can see here a bit about what I am making lately. It will be a SW mod for this non-released game yet. Have fun.

This is a great mod! We're really looking forward to diving in once you've completed it!
