HAHA! He might be! I think they do have some sort of zombie edition of Call of Duty, i'm not entirely sure though.
Agnes is basically your loud, obnoxious, party girl. She thinks she can do whatever she wants and damn the consequences. She's not a very moral girl and she usually causes more trouble than she helps..she also looks out for #1. Which would make her a horrible addition to any zombie "team" lol.
