"News to some, friendly reminder to others, but the Left 4 Dead mod "Dead Before Dawn", a mall-based homage to "Dawn of the Dead," is no ordinary mod. Anyway, "Dead Before Dawn" hits on Oct. 31. The modmakers are working feverishly, and promise that they will put something out on Halloween. Further, yes, that is a fifth character in the poster; yes, he is C.J. head of Crossroads Mall security, and yes, he is playable." Source with many screens and more info.
