The sheer fact that it's not necessarily a "monster" so much as it is a dead, demented human being makes the thought of encountering one a nightmarish idea. So what then would you do were you trapped in a town, a town overrun with the undead, with three other people, and you had one night to escape? Try to survive, that's what. Valve Software are aiming to take that simple premise, one that's been used in countless movies, and turn it into a "blockbuster, cinematic" interactive co-op experience with Left 4 Dead; their brand new survival horror FPS for the Xbox 360 and PC."
