== Door Bug == 

 I don't own this game, but apparently it has or had a door bug, where in hard mode a certain door doesn't open. [url=http://www.youtube.com/watch?v=nQr1AvIuGAY this YouTube video] has over 100 people thumbs upping "Thumbs up if that son of a﻿ bitch door bug brang you here!" and pretty much all the other comments to the video appear to be about it. I searched this Wikipedia article for "bug" and "door" and got no matches. Maybe information about the door bug should be added to it, it's quite a big deal if a game like this has a major bug like that.
