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 developed a new feature for the clone wars companies. It is a special filter system, without buttons. Now by example there is a option for to build all the available walkers, depending from your tech level and the factories in the planet. If you are at tech level 1, you will build only the SPHAT and the AT-AP MKI but if you are at tech level 5 and you have the light factory, the heavy factory and the advanced heavy factory, you will build all the walkers from the republic.
Looking good, can't wait to try it out:)
