Las Vegas, a city of lights, a city of sin, the perfect place for a private underground government laboratory. Substance 666 was being used to bring corpses back to life. It seemed to work very well. The corpses showed signs of memory after a week. The government was exstatic with this new technology, but further tests were needed to be sure of stability and usage planning. However, it seems that after 2 weeks the corpses would began to return to their state of physical being, rotted and torn up, but they were still up and about. As this continued the process slowly deterriorated the brain and muscles. Their minds were only capable of remembering primal instincts, such as to eat and groan. But for some reason they didn't want corn or chicken, they craved flesh, human flesh. The scientists not knowing what to do shut down the base but that didn't matter the chemical had already gotten into the waterline, the waterline of some casino. People began to turn into undead flesh eating freaks! Do you have what it takes to master the arts of team work and zombie slaying??? I hope so.
