On my first time playing (the new map), when I was well under equipped, out of ammo, surrounded by spider spawns and not sure which way was clear of anomalies, I died at the top of that hill. Then just now, coming back with [spoiler]the grail[/spoiler] I die in the exact same spot. No ammo left, no knives, over encumbered but just a short dash to the fog, surrounded by the spider spawns and fragments I ran past on my way to the castle. Was old is new. Couldn't help but laugh after spending probably an in game week in the radius on that mission, killing god only knows how many mimics and sliders, then coming back to collect my corpse and seeing the grave marker glowing right in front of where I spawned in. 
Somehow I never seem to be able to bring enough ammunition. Every high priority mission I am down to my last few shells or I've managed to scavenge a couple off corpses or crates just to get by and then every time I bring more and for stronger weapons but it's still never enough. The difficulty curve for each major mission is exponential and massive. [spoiler]I've found all the statues so I've only got one left now.[/spoiler]
