If you have ever played sims of any sort you know abot how you can customizable voice. picking a start of voice and chosing how deep or high it is. Why can't the do that in Halo. The same basic thing for Halo, but maybe they could go even further. Like chosing what your person could say. Like you get 10 different phrases out of around 50 or so. It could also be used maybe for multi-player.
So you want everyone to download a unique voice for each and every player they play against everytime they play?
I played sims, I couldn't choose my voice. Why do you even care about your "voice" in firefight, now, I've never played firefight, but I hope they don't just repeat the same 10 phrases again and again
