Forty it The map around us has 3 factions: Evil Parachute CORP. Traders. Zombies. There are at least 3 trading camps around us. The Umbrella Corp keeps to itself way north. About 3 miles. It's been 58 years since the zombie virus took over the world. My party has been fortying the school and only have to deal with Zombies once a week. They dont wander to crazily. Deep in their midst there are variations. We've heard of jumping ones, charging zombies, hearing zombies, big tank like zombies, hunter zombies, theres no knowing what other kinds there are. We've managed to fortify the doors and have enough supplies for a good amount of time. Maybe we should gain followers? To help create bullets. Or take out rival clans...what do you think?
