Without dropping any more potential spoilers, the game really ups the ante, heaping more terror and intrigue onto the player than possibly any comparable horror game has managed for years. For a good number of hours, it's true survival horror, forcing players to really keep their wits about them, bolting doors in the faces of aggressors and shoving bookcases up against them, jumping out of windows, fleeing across rooftops and ducking bullets fizzing through windows. There's never really been a game that terrorises the player's nerve to quite the same extent. It's unflinchingly brutal.
