chapter 13, the 2nd floor or the 3 storie walk down before a tripod monster. 3rd save, I opened up a door to a staircase that was all dark. Because I'm sick of this game I keep my finger on left bumper to run everywhere, and without thinking I ran they the door which was glitched and fell down continuously in darkness to my death.Doh!!!
I'm trying not to watch video walkthroughs anymore but I may have to.
