Hey, I just logged in with my UPlay account in ZombiU. I saw that I have a couple of "chievo" and I also spotted this one. Does this mean I have to go all the way through the game if I missed one camera? I'm around the middle of the game I guess (Brick Lane) and I'm not sure I've got all the cameras hacked... how would I know? If I finish the game without one of them do I have to go through the whole game again?
