You've just killed Fettel, and are now in a hallucination being pursued by Alma. All of a sudden, you're at the end of a hallway you've seen in a lot of your visions. On the other side of the half-glass door is the room in which you were born. You can see your birth happening (you don't actually see it, as the doctor is blocking it, but it's heavily implied). Suddenly, you see Alma walking towards the doctor. She touches him and blood sprays all over, covering the window. You turn around, and see Alma walking at you from the end of the hallway, occasionally teleporting some distance down the hall. You take out your pistol and take careful aim. You begin shooting her. If you take too long to kill her, she reaches you, touches you, and you insta-gib.You have multiple 17-round clips, but if you take the time to reload, you die. You have to shoot fairly fast and very accurately. If you manage to finish her before she kills you, she just disappears, and you get the epic reveal of Alma's true identity. The rest of the game is simply coming down from that climax, with the occasional vision of Alma and/or nightmare fight. That climax is pant-wetting though. You can see it here.
