This happens after you get to the radio tower and send out the message. I've gone down the ladder at the side of the building, and gone back out the entrance to the building and walked round, but everytime I approach the gap in this fence my screen goes black and I get the game over screen. It's not like when you usually die at all; the guy still makes a noise as though he's been hit, but rather than going red and dropping to the floor the picture just cuts out. I thought maybe I had been sniped, but even crawling along the outside, out of view of anything makes it happen. Tried about six times now and it happens every time. Am I doing it wrong or is this a glitch?
 
EDIT: I quit and loaded the checkpoint back up. This time it saved after going down the ladder, but as soon as I walk forwards I die again.

go around. this happened to me, but head back into that house. There is a way to go on top of house and slip down the side, so you dont actually have to go through that fence.

Yeah, I figured it out eventually. There's a hidden staircase in the building that leads into the basement. It's just dumb that they made an obvious looking path that kills you if you go near it. Should have just cut that bit out and stuck a fence there so you couldn't actually go that way.

yeah, it kinda sucks. im still not exactly sure what kills you in the first place.
