I played SOMA and both Amnesias and other horror games and all that good stuff - scariest game, by far, is still DayZ mod. Nothing is as scary as going, “Alright, I’m fully geared out” and hearing the crack of a rifle bullet whizzing inches from your head.
There was one day in particular where I just hadn’t been able to get good gear without dying for weeks, so I got desperate and went to the military base in the middle of the map (forget the name). There was a guy camping out, watching the main loot spawn. I spent hours literally crawling through his line of sight - hearing him occasionally kill other guys, to remind me he was still there - to get to the secondary spawn. Get in, find an ok-ish gun, and try to sneak up on him after more crawling. Hear a shot, see the dirt next to me kick up, panic and run, boom, dropped.
Hours of work, deleted by two shots. It was so terrifying.
