Much of the start of the project was spent defining the rules and systems of the game. In the interest of keeping things simple, everything was conceived in threes. Three units, 3 resource types, 3 room types and 3 primary systems. How everything related to one another was next. This triumvirate is expressed in the Venn diagram above.
–Zombies kill survivors and destroy rooms along their path, but will not steal resources.
-Bandits steal resources [food or salvage] and kill survivors, but will not destroy rooms.
-Survivors gather resources and build rooms, but do not kill other survivors.
