Save the Colony! Your staff are brawling, the Harvester Robot is happily chain sawing its way through the oxygen supply, and small, furry, and troublesome aliens have conquered the disco. Welcome home! Each of your colonists has a mind of their own so remember the golden rule: a happy colonist is a productive colonist. Ignore them and their needs and they’ll pick fights, argue, and even get depressed. Nurture them, however, and they will work hard for you, become friends, and maybe even fall in love!
