GDN writes: "When I first heard that Valve was developing a "zombie-shooter", way back in the early Summer of 2008, I was skeptical. Although Valve was the creator of some of my all-time favorite games (i.e. the Half-Life series), I was never much of a zombie fan. The mythology seemed a bit silly - slowing walking creatures of the un-dead, with a taste for brains? In my mind, a zombie apocalypse could be simply avoided by walking faster."
