Guys we should escape then get back to my place, we can hide up in my tree house.
Yea that's sounds good.
People come out to see what was going on and they find mutated people walking around, terrified they run away.
The 4 teens come out to see the people of the city are running around and yelling while they're in the middle of all this commotion and as they stand there the zombies get closer to the heroes.
They find a store that was nearby and hide from the zombies and the zombies start tapping on the windows of the store and they start trying to get in through the door, so they quickly come up with ideas and get out a new way. But then everything stops and the zombies go away.
They wait till the zombies go away and they stay quiet until they know they are safe, then they sneak by the zombies without any sound and get back to the town.
They come back and to find that the zombies have taken their town too and zombies are surrounding the house where they need to go to.
They find a way to get past the zombie by using their skills to fight off the zombies to get a path to the tree house.
