Detailing is amazing, incredibly rich detail which makes everything that bit more realistic (and works well in tandem with the darkness). Although, I did find the darkness incredibly annoying whilst navigating the manor, being boomed on, and chased by a horde to a helicopter I didn't know was there until I could hear the radio (ironically, I think the manor segment would work brilliantly with L4D2's gauntlet system). If there was one other thing I didn't like, it was the wall scribblings. There were far too many wall scribblings, they were in nearly every room I came across, and I just couldn't be bothered to read them (which is part of the joy of the wall scribblings in L4Ds), I had "wall scribble fatigue".
