The programmer used an algorithm that generates each planet and base, including its inhabitants, using a single numerical "seed" on the game disk - a trick which enabled them to have 65,535 levels in the game without having to store the details of each level individually (only one base is "active" in any given saved game, since each base must be "destroyed" before moving on).
The game was known as "Federation War" while in development, but a reader of ACE magazine came up with the name Captive in a competition.
