Alien Isolation: Nightmare Pacifist Deathless with Unpredictable Alien!
It may sound counter intuitive but using Unpredictable makes the game harder even if you encounter the Alien less, because each encounter is harder to survive to!
I'm using a bunch of QoL mods and a pretty cool and new mod made by a guy named Darkstar which makes the fake light around Amanda disappear, for true darkness inside vents and lockers!
I think this game is a fantastic experience despite it's game design problems, it's one of those games where the "game" isn't that great, but the experience you'll have while playing the game is going to be fantastic if it's your thing.
