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 made some special modifications for some units following some units published at Wolfsshipyard.com . With these changes, the amount of different units will be increased.
These special new units will be different from the others, specially in the abilities and their role in the game.
I like how they almost look like Hammerhead Cruisers from The Old Republic.
