Colony Builder
This supplement for the Cepheus Engine and HOSTILE setting provides tools for creating and managing extrasolar colonies. Players establish a colony’s purpose, sponsors, budget, environment, infrastructure, vehicles, and robots, then take the roles of key personnel responsible for its survival and finances. Colony management involves addressing problems such as hunger, air loss, earthquakes, alien parasites, and other hazards while balancing costs and production. The book also covers the origins and organization of colonial projects, human requirements, and a selection of specialized vehicles and robots.
