October 20, 2011 at 5:55 PMWas wondering who the character is that is “unknown.” I was exploring the city when i came across a man who left behind a symbol after speaking to him. When i check the character bios, his name comes up as Unknown with no information about him. I have currently found him twice in my game but my roommate has yet to find him once… HELP!!
