I've never compiled a legit voice acting showreel, but I plan too make one soon. Check out line of Fire on the games pages for some of my voices. Some other stuff my voices were in over the years include Damn Birds 2, The Eater, TRN47 Subversion, and Apocalypse Later, coming soon. I've also been on the radio in canada as Arnold Schwarzenegger - my most legit role to date!
I love voice acting, and plan to put some real effort into it over the coming year or two. If you have any legit roles in upcoming projects and want some demos, just ask ;)
