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.
Time for some additions. This time some interesting units seen in the Rogue One film. The TX Tank, TIE Reaper, AT-ACT, TIE Strike and Death Troopers. All new additions to the mod and they will not be the last. The next days, I will add some more for the Rebels, not from Rogue One but I am sure how you will know some of them.;)
For your information, it was my first in game test, there are somethings which they must be fixed. At first place the TX Tank guns and the TIE Reaper, I made it as a transport but it was a bad idea because the transports does not run very well in the game, perhaps I will make it for deploy troops or some like that.
Other units seen in the video as the Heavy Tracked vehicle or the ATAPT, you could see them with other factions but in the 8.0X, the Empire can build them.
Ah one thing more, I was playing in easy and by this reason you can think how the AT-ACT is very powerful but really, it is a lot less powerful than a AT-AT.
