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.
Lately, I have improved the AT-IC and the AT-L. If you do not know it, it is a AT-AT with a big turret in the back. This vehicle always was fun but it had a problem, it was a mess put the big gun turret in the direction from the enemy. Now the AT-IC/AT-LC walks at reverse mode and thanks to it, you will have not problems firing the enemy in front of you. Have fun.:)
