i made a mistake and got through the large gate in the surveillance room and went right on to the east gate and north gate without completeing the surveillance room with hh. is there anyway to salvage this or am i gonna have to start over. thanks for your time

Marz as far as i know you will have to start over .....I am only a little ahead of you in the game and i have run into a real snag and have been stuck on it now for the last three playing sessions ....... I am in the slaughterhouse and have taken two of three necessary pictures..... and have no clue as to where or how i take the third..... I am in central hall and just running in circles again and again and....

I had the same sort of problems, but I found a solution, if you get past the gaurd where at the end is the x-ray machine which you have to take a picture of the "Human Traffacing", there is an entrance to a closet which lets you out in a different room, from there you can get the 3rd picture.
