Yes, we still have a forum.
How does the traitor system work? Seemed really interesting.
I'm still early in the game so it hasn't affected the gameplay yet. Apparently the traitor is random so that you have a different experience on multiple play-throughs. Basically after every battle there are rest periods where you can choose to converse with your teammates, I guess you are supposed to determine you is the traitor based off of what they tell you.
