There are over 300 different ships and ship mods to choose from and a wide array of weaponry.
Missions range from escorting and patrols, to space monster investigation and starbase assault. The campaigns are randomly generated by the 'Dynaverse' generator, with certain key missions that will come up as the player go through their 30 year career. They begin with a small frigate class ship, and as they complete missions they gain prestige that is then spent on acquiring larger ships, and better crew. The player can choose to play a career that will span 30 years as the captain of a Federation, Klingon, Romulan, Gorn, Hydran, or Lyran ship.
It is based on the tabletop game Star Fleet Battles and it follows its rules almost to the letter. Star Trek: Starfleet Command is the tactical, ship-to-ship combat simulator set in the world of Star Trek.
