From publisher blurb:
The stock of medical supplies is perilously low, the water tower collapses, and the rumblings of racial tensions arise in the camp. Can the players keep the camp from falling into chaos? This event includes three threats (The Insiders, Thicker Than Water, The Thick Red Line), each with its own suggested summary, stakes, and countdown.
Remember, as in most Apocalypse World type games, COs should not treat this as an 'adventure' on which the players must follow a predetermined path. Instead, use this event and its threats as starting points so everyone can play to see what happens!
