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 was curious about how difficult could be mod the SOASE Rebellion game and I started it, it was the first time that I worked more of 10 minutes with softimage and probably if it does not explodes at my face, I will continue it. This game has one thing which I like a lot, it runs at my netbook, the minimun requeriments from rebellion were increased but even with them, the game can run at a netbook with a atom processor and 2gb of ram. Have fun.
About the code, it is not too difficult. Of course by the moment it is only one mod for enjoy I only. If I finish something good, I will release it one day.
