Zombie apocalypse

The Zombie apocalypse is a certain scenario of the Apocalypse fiction that usually fits into the horror/science fiction genre of film. In this scenario the world is usually taken over and ravaged by a race of infected beings, better known as zombies, who are undead and feed on the living. There are a number of ways that victims become zombies, ranging from being bitten by an existing zombie to breathing in an air born virus. In any scenario this generally leads to a 'zombie plague' that swamps civilisation and all society. In films like this there are usually a group of survivors who are immune or have avoided the zombie virus, who take it upon themselves to either rid the world of the zombie race or simply survive as long as possible.
