Generic Zombie Survival Game

It only took a couple weeks for the virus to spread to every corner of the world. Whole cities completely abandoned overnight, quarintined and sectioned off. First believed to be a cure for athlete's foot, the miracle "cure" kills its host in a matter of hours then their corpse reanimates, seeking victims and eating their brains. Your name is Laurence, an ex-marine who now works in a mall at Taco Bell (or what's left of it). You've woken up at work, completely alone and confused. The radio is playing an emergency broadcast on repeat. It seems the government has decied to bomb the whole east coast in a last ditch effort to stop the virus from spreading. Any and all survivors are encouraged to leave the vicinity and reach one of several evacuation sites. You grab a couple of burritos for the road and head out.
