I really liked the show overall, although I have lots of little minor complaints - still the serious tone is more appealing to me than Zombieland.
Years ago, when the Dawn of the Dead remake was just I out I formulated Escape From Tacoma for paintballers up in WA. The old Patriot Paintball field was an inspiring, the already had several junked boats and some pond areas plus a layout that had two speedball fields flanking the safe zone giving the field a C-shape. Fortified survivors of The Neighborhood Watch squared off with a motorcycle club, The Volcanoes to get control of a ship from the harbor that could carry them to Australia. Periodically players would recycle, as Zombies, at the other teams normal entry point - they could trot through the cover of the speed ball areas to quickly assault the other teams "stronghold". Character cards gave each player one or two skills that ultimately would be needed to repair, provision and operate the ship, for example at one stage three mechanics and an electrician plus one extra hand need to stay adjacent to or aboard the "ship" with "tools" for a 10 minute period to generally overhaul it, then the guys who were sailors or navigators (inc. the High School Geography Teacher) had to find the "charts" needed to get them to Australia, and treasure had to be collected because the Quarantine forces would charge a toll, etc.
I think that The Walking Dead background is a good one for role-playing Ops, I'm looking at setting up a series of games using the Firefight LARP system
