„Star Trek: Fleet Captains”, designed for two or four players, is set in the „Prime Universe” of STAR TREK (as seen in the various TV series and movies up to „Star Trek: Nemesis”) and is more adversarial in nature when compared to Star Trek: Expeditions.

Each player begins play with a fleet of ships and starts at opposite ends of an unexplored sector of space. This sector of space is represented by hexegonal cards (which are shuffled before play and placed face-down in a pre-determined pattern). As each ship progresses through the sector, you turn the tiles face up, revealing what is in that part of the sector (a Class-M planet, a Class-J Nebula, empty space, etc…). Hopefully you will discover and acquire resources while simultaneously denying them to your opponent(s).
