Shaun of the Dead actor Simon Pegg tweeted out earlier today that Left 4 Dead mod idea is "absolutely awesome!". Though he gives his unofficial blessing to the mod team, he knows that Universal holds the rights to the license . Even with that hurdle he vows to offer what support he can to see it come to light.
There aren't many details right now but you can watch a short teaser promising to answer the question, "what if the best zombie game had a baby with the best zombie movie". Currently dubbed Left 4 Winchester we can surmise that the campaign would involve Shaun and the gang seeking shelter at the eponymous pub. He's hoping for an encounter with a Tank while Queen blares from a jukebox.
