How to Save a World

How to Save a World is a competitive science-fiction strategy game about responding to an extinction-level asteroid on the wildlife-rich planet Alarria. Each research organization sends landers to worker-placement locations, improves its technology, manages resources, and builds a hand of action and boost cards. Effort flows into three possible projects: a laser that can destroy Leviathan, a shield that might deflect it, and a last-resort evacuation of species to the nearby moon. The pivotal project is determined only after the asteroid arrives, so contributing broadly preserves options while specializing can secure the largest rewards. A bag-driven impact system and shifting facilities create uncertainty, but visible project tracks, hand development, timing, and blocking decisions keep the crisis highly strategic. A dedicated SiMu deck turns the same systems into a substantial solo challenge.
