Horror movies are for perverts. If you want to get some cheap scares and nasty shocks why not go and play in motorway traffic or intentionally walk in on your parents having sex?
Horror games on the other hand, those are a different proposition. They can grip the player much tighter and play on what makes people scared far more effectively. A great horror game plays with your perception of control, it can draw you into a world far more deeply and evoke feelings of panic, isolation and desperation in a way that few films can achieve.
Does Dead Nation, developed by Housemarque (of Super Stardust HD fame), manage to elevate itself above the swelling mass of zombie games on the market or does it get dragged down and eaten by the hordes?
