Survive the real zombie apocalypse on the streets of the U.K.

The zombie apocalypse just got real.

A giant urban zombie game kicks off in the U.K. this week, with players running through the streets of Cardiff in search of a hidden lab, all the time evading hordes of the undead. 2.8 Hours Later is a ticket-only event created by real-life game company Slingshot. Players get emailed a start location then turn up to start their 2.8 mile adventure through the city streets, trying to avoid getting infected by the marauding zombies that stand in their way.
