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.
After a lot of work, I could manage to get a good animations for this three legs walker. I have not played Kotor game and I do not know it walked, in fact, I prefer do not know about it. Sooner or later, I will add the other walkers from Kotor.
