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.
A small preview from the last update and the Imperial soldiers made by tj666. There are many additions and changes. First the Stormtroopers have a 24 man company divided at two 12 man groups. These groups have soldiers with several different weapons, ranks, even a medic. Very different from the previous.
Other units as plextroopers, stormcommmando, heavy troopers, all them have new additions, even the building survivors will have changes.
At the same time, these new Imperial models have better animations, correct animations.
In addition, in the last upgrade infantry survival is bigger against big weapons, in fact most of the big vehicles can not target them easily. At the same time the infantry can damage heavy vehicles, just a bit but they can damage it and if a heavy walker is attacked by several infantry companies, probably it will suffer enough damage.
