Yeah, ****ing Amnesia.
I did the DLC Justine level for the potato, I was near the end and was like "Pfft, that wasn't scary", then I put a cog into a machine and heard a mighty roar, my first though was "That can't be good", so I ran and closed all the doors/gates behind me at which point the monster is supposed to be shut out and you're safe, oh no, not me. I mustn't have shut 1 of the doors properly because I heard "THUD THUD THUD" right behind me, I turned around to have a huge monster screaming in my face and charging at me. My only reaction was "OH ****! OH ****!" as I sprinted for the exit door to get back to safety. I don't think my heart has ever been thumping as hard playing a game as that moment.
