Say you're vacationing in England for a couple of weeks and a plague breaks out among the streets turning people into bloodthirsty undead monsters. Because of said events, all the major important companies stop supplying England with food, water and resources.
You, who has little to no experience with firearms or survival, are alone, cold and hungry.
Zombies are dumb, their senses are dull, and they're dying. According to the news channel, the plague is spread through the bloodstream (bites), and it kills the victim under four weeks.
So, everybody but you and a few survivors scattered around the island are left, and it will be twenty eight days before any chance of help is, since everybody's being paranoid of the plague and not sending anything to England.
And one last thing. According to the news, anybody who tries to escape will be shot by patrolling boats around the bays and coasts of England.
How would you survive?
