Concrete Coffin

Game premise and management mechanics

Concrete Coffin is a survival management game set in an underground shelter after the surface has become uninhabitable. You play as the Governor, responsible for maintaining the life-support system for 11,581 people in a facility designed for only 10,000 individuals. Your goal is to keep the shelter operational for 10 weeks (70 days) by managing six core resources: Reactor Power, Population, Food, Water, Morale, and Disease. If any resource fails, it can lead to catastrophic outcomes, including famines, epidemics, or reactor explosions.

Resource and advisor management

Each day, you'll receive incident reports from advisors, including the Chief Engineer, Security Chief, Chief Medical Officer, and Communications Officer. These reports highlight the current state of your underground community, and you'll need to make tough choices that often involve balancing the needs of different resources and the loyalty of your advisors. Decisions may strengthen relationships with some advisors while alienating others, and you'll constantly monitor the effects of your governance on the shelter’s population.
