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.
Most of the Legacy ground units were in the mod before. However, there will be some variants. You can watch here most of the ground units from the Krayt Empire.
You've done some great things, Nomada. Excellent job!
Looks rather outstanding. Loads of units, some great, some not, but overall seems as it did until now. One of the best mods for EaW and one of the very few that are still here with us today, even after filefront died.
(But you should add 18+ tag. Those walkers at 3:20 really shouldn't do this publicly.)
