So, it was past midnight. My brother and I were checking out the new DLC for Fallout 3 called Point Lookout; it had just been released at the time. He was the one playing, and I was on the bed next to the computer, observing. Finally, he arrived. He went through the levels pretty quick, witnessed the hallucinations and the self-opening doors. We weren't really scared by any of that because we knew it was going to be there. He got to the under-chambers and placed the book on the creepy-looking altar, and it somehow completed the mission by destroying the book.
