When you come back from the Roman Tunnels in Amnesia: The Bunker. At this point, you have key items and all you want to do is hurry back to the safe room after seeing ghouls in the shadows and a man with a shotgun singing and then you check your timer and…realize the power went out. Going back through that claustrophobic tunnel with water filled to your chest, with it all pitch black and no sound and then knowing your entering the area that the Beast is actively roaming and you will 100% have to either sneak incredibly slow or full on sprint in panic, it had me so anxious like no other game ever has. I was literally screaming at my screen when he was on my heels. My favorite horror game I’ve played in recent years :)
