When I pull in, the people there are waving their hands and giving me the sign for Keep Quiet. Unfortunately, the bus backfires loudly and shutters to a stop. Everyone freezes, silently looking around. From every doorway, shadowy figures emerge. From all directions, they swarm the gas station. I open the door and tell everyone to get in. Moments later, we are surrounded on all sides, bloody hands on every window. Now you are trapped in a bus with people that hate you and zombies all around. The only way out of this, is to fight. You rally the survivors, getting them to focus on making weapons.
