The Zombie Apocalypse is in full swing. Your group of survivors has been driven out of your last safe house. Hungry and weary, and being pursued by an ever increasing mass of undead, you stumble across an abandoned roadhouse bar and grill. You are able to locate and activate the pub's emergency generator which provides you with a minimal amount of light, but more importantly, activates the bar's security features which should keep out the horde of creatures on your trail. But the generator only has one hour of fuel remaining.
