The Dead Space development team have put up a new designer diary for those that might be interested, called Inside Terror.  This diary has the development team talking about how terror can be portrayed in a video game.  Is it a beast attacking, or walking into a room with walls that are covered in blood, knowing something horrible has happened in there.  One thing I do have to say, that Dead Space, along with Project Origin are shaping up as my PC hits of the fall.
