How did your game junp right to gear boy chapter 8??! I've unlocked all the chapter's and completed 1-7, but after doing 7 it cuts to a scene with Sally and Larry and doesnt let me use the gear boy again AT ALL. Not having done chapter 8 is the reason I've not got 100% completion in the entire of that chapter. I've replayed it so many times and it's just the same thing..cuts off after game7, I'm so confused...
So, you actually need to play chapter 8 before 7. I changed the order, so it was chronological in the video. To get 8, you have to go into Sanderson's room. Take the crowbar from David and use it to get the planks off of her Sanderson's door if I'm remembering correctly.
