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.
I have added two vehicles to the Hapans. A special T2B and more simple AT-BT. I will improve the AT-BT one day but by the moment, it goes to be as you see.
The AT-BT design comes from here Jasianinvasion.blogspot.com.es
will those cannons be the same as AA turrets?
Yes, it is the idea. AA weapons + a grenade launcher.
These aren't bad actually. The extra barrels look fairly natural. Nice work.
