"If we went up to a second floor, we could board up the doors and have people covering the stairs with guns." John paused. "Of course we don't want to get trapped inside anywhere with monsters. That means we need to be able to keep them out, but not trap us inside. We don't know much about them, if any can fly, we could be on a fifth floor and not be safe from them." John looked around, gripping his shotgun. "Either way, we should stay quiet until we find shelter, we don't know what is out there and we could be attacked at any time." John continued scanning the surroundings, looking for anything out of the ordinary, ready to fire at any time if something attacked.
