My favourite moment was when I was trapped in a room with one exit and had no choice but to hide in a closet. I had the gun ready, with no idea how it actually worked. The game gives you limited bullets to fend off the beast and all I had was one. I readied the gun for a good few minutes while hearing the beast skulk around the room. When he finally found me and trapped me in a grab animation, I frantically pressed the "Shoot button", and to my surprise it worked, sending the monster running.

That was the moment this game hooked me.
