The game is for two to four players and can be completed in about an hour. It is played on a large board depicting Union-Alliance space with jump-points and space stations. Union and Earth Company ships, represented by counters, are moved about the board via dice. The aim of the game is to collect the most points by transporting goods between stations and destroying enemy ships.
An unofficial variant of the game (with Cherryh and Fawcett's permission), Advanced Company War, was developed by Christopher Weuve in 1997.
