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 a new video for you. This time, you can watch the Terror units at action. Judge by yourself.;)
Anyone else remember that scene in the Force Unleashed II where Boba Fett met the terror units? I think even he was a bit startled, and he's seen most of everything.
