Yikes!  Call me a wuss, but some of the areas in AvP made me jump out of my chair!  The atmosphere in most of the levels are very dark, so when something JUMPS OUT AT YOU, your heart rate tends to skyrocket!  The  facehuggers are especially nasty (and cheap), jumping out and landing on  your face for an instant kill.  My god, when a facehugger jumps on your  face, making an awful hissing noise and quite abruptly takes up 80% of the  screen, it's a wonder why Fox Interactive hasn't been sued yet for causing  a few heart attacks!  And man, this game is HARD!  But, Fox has released a  patch with a save feature, so it's okay now.  Believe me, this game is not  intended for the faint of heart!  But, for those of us who aren't, go out  and BUY this!  And play it at night too...with the lights turned off.
