Welcome to Seabrook. We're a perfectly planned community. We all have perfect homes. Perfect clothes. The perfect life. Yep, everything is perfect. Until it wasn't. Who would have thought that an accident involving lime soda would set off the apocalypse? And when the contaminated green haze blew west, people were not happy. Because it turned them into... Zombies. That's right. Zombies! Brain-eating... Zombies. Dark and gory times. But we built a big barrier to protect us from the zombie hordes. Safe at last, Seabrook could finally get back to our perfect lives. Well, a lot has changed since they built the barrier 50 years ago. Science found a much better way to deal with zombies. And you know what happened to those old brain-eating monsters? Well, they still have to live on their side of the barrier, but now they're awesome!
