I guess everyone knows what a zombie apocalypse is, Right!

So, Rorke and his friends are at Rorke's house for a sleepover when all this takes place. They get out from the street to the nearby hill where they find a decent house to live. 

There are further more problems, as more zombies near thye house due to noise, lack of proper food and forming of bad gangs. they then head to Bankstown Bunker, Australia.
