I only find collectable photos on younger sister. And after that I can't find any photos despite I already follow the walkthrough. Does this action will change the story? Couse seem my gameplay is still same story with the walkthrough.On the subject of the chip have you bumped into Debby yet in the Police Station as the chip will be on the floor and will still be there even if you leave and go back as for collectables what ones are you missing and I can direct you to where they are
