For those who want Internal Access it will be relatively simply. Once this game funds participate in our forums. Help us by suggesting things, taking part in polite debate and show us that you are willing to spend the time to help us make Camelot Unchained great. If you can do that, Internal Testing will be waiting for you, I promise.
