Very strange. Does it give you a perticular message when you try and change the voices? Have you tried using rebed to chage the voices? I think you can use it to do that.
I am asking because of my intention to build myself a sith costume. And any tips could help. What are you dressing up as for the next convention if i may ask?
I tried the demo. I have to say it was fun even if there were only two levels. I think the gameplay needed work but this was an XBox version so i guess the pc version must be better. I will have to give the full version a try now.
