Over the course of the game, the mother ship can be equipped with up to four add-ons: freight rings representing the trading ability of the player's ships, boosters representing the speed of the player's ships, cannons representing combat ability, and fame rings representing the overall fame of the player's ships. At the start of the game, each player begins with only a single fame ring, and, in a 5-6 player game, a booster and either a freight ring or a cannon.
