Nothing like having the living hell scared out of you repeatedly!
Pros:
Great graphics, story-line, monsters, intense-factor, high heart rate
Cons:
Sometimes repetitive, damn that PDA
Fun Factor:
Very high. Not ideal for all audiences but if you like getting scared, love horror movies, then this game is for you. Ideal playing environment - bottle of scotch, candle-lit room, 5.1 or higher surround sound system, largest monitor available.
Great addition to anyone's library. Bring on QUAKE IV
