About

A Lunar Crisis

Read full description

Can you survive where no one is coming to save you? Lunar Crisis puts you in command of four stranded astronauts, fighting against time, isolation, and failing systems. Your mission: repair a damaged ship on a dead moon—and get everyone home alive. This is more than a survival game. Lunar Crisis is a test of resourcefulness and pressure management, crafted to teach probabilistic thinking. Monitor, repair… or perish. Lunar Crisis is volume 2 of the Mental Model Minis Series.
