I have always been a big fan of co-op games and zombie games, Left 4 Dead is the epitome of both genres.
The game continually impresses from it's gloomy, creepy atmosphere. Atmosperic sound, unnerving lighting and terrifyingly smooth animation of your enemies.
While the only knock against this game is the lack of many campaigns, the procedural AI director keeps things fresh by making the experience original everytime you play.
An instant classic that should not be missed, or played without friends.
