Hi guys. I've never played UFO:Alien Invasion. However, I recently became aware of the XCOM series, Xenonauts, and a few other games. I've been XCOM: Enemy Within. Anywho, can do a few voices, nothing too special, but probably better than average. For example, I can do a 100% perfect Gollum voice from the LOTR films. I may try to play UFO:AI tommorw.
FYI, I was BORN with a complete lack of ability to play video games and succeed in them. :/
But like a battered wife I always go back to them.
I use Steam, Skype, and email. (but I prefer skype.)
