Star Trek: Fleet Captains, designed for two or four players, is set in the "Prime Universe" of STAR TREK. Each player takes the role of a faction (or race) from the universe. In the base game, the choices are Klingons and Federation. Each faction has a number of ships (on Clix dials similar to the Heroclix line of components) of varying ability and with a corresponding “size.” Fleets of ships are drafted to a given size total which reflects the victory points required to win. Thus, larger fleet sizes lead to higher point (and longer games).
Players then “shuffle build” a deck of command cards. Choosing four decks from a set of ten decks per faction. Each deck has a unique flavor or theme, with corresponding major characters. For instance the Klingons have a deck themed around larger ships and imperial domination and Gowron is a central character. The four decks chosen will help to set the player’s strategy for winning.
The ships chosen have physical stats like weapons, shields, engines, and sensors. They also have mission totals for science, influence, and combat missions. These determine the kinds and numbers of each kind of mission cards the player draws to form a mission deck. Completing missions gains the player points, which will win them the game. Missions could be as simple as damage an opposing ship that is larger than your own (combat), to as complex as claiming the spaces connecting your command post to your opponents (influence). Thus a player’s chosen ships sets the types of missions they will need to earn points and the deck they build determines the way they will complete missions.
