From the introduction: High Colonies is a little-known role-playing game originally produced by Waterford Publishing in 1988. Set in 2188, the game posits a future where the Earth has been destroyed by nuclear war, and humanity clings to a precarious existence on a number of space stations scattered throughout the solar system. Player Characters are normally members of the various mercenary units used by the smaller stations to maintain order and provide defence. I ran a High Colonies game for awhile in the early 1990s, which gradually mutated until it merged with my 2300 AD campaign. I wrote these scenarios for the game, which were published in Challenge magazine. They also work well in Traveller or 2300 AD.
