Extend the Story - Add a Room

You begin to move slowly. Your already ead body cannot walk very well. You shuffled and stagger towards the building. You quickly blend in with the crowd of zombies. Only glass doors stand between you and your meal. The numbskulls surrounding you clearly have no intellect at all. They are going for a single entrance, but perhaps their combined weight will be enough to destroy the humans' defenses. Another choice is to go around to the back entrance. If you were to enter on your own then you have all the living to yourself, but then there is an added chance of you being put to rest by them.

Go around to the back entrance.
