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´m playing the mod at a Steam version and I do not see to the black sun attacking me with more of one darksaber.
So their limited to 1 per-battle at a time, if so thank god. I remember getting swarmed by Darksabers if i didn't destroy their space stations quickly.
oh thank god i thought it was just me
hahahaha!
Well at least if there are so much Darksabers the Hutts had all astroids melted to metal I guess? ;p
