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.
This other is a video showing how the new capture ships ability works. Now you can capture even enemy stations. Have fun.
Of course after the battle you will not get for yourself the enemy starbase. One thing which it does not happen when you capture enemy starships and you can use them forever.
Nice, Cool Mod!
