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.
As you can see, I renamed this small cruiser and I have given to it a more correct name. Other points, the First Order will not be a new faction but there will be a complete GC with it, it will use icons as you can see here and in the GC, you will build units only from the First Order. Just it. Obviously the Resistance will use a similar way.
Other point, probably, I go to remove the flags from ground landing zones. Just the colors are more than enough.
About when be added. My plans are add each unit finished with each upgrade. I do not go to wait a year and next release everything in a package. It is not fun. Anyway, it will take time as always.

Quick question, will the first order's units be available to the standard empire in the total war GC?
Yes.
