Starfleet Voyages is a science-fiction adventure role-playing game of planetary exploration based on the Star Trek television series.

Most player characters were assumed to be members of Star Fleet engaged in planetary exploration missions.

They typically held senior posts on a starship bridge and visited alien planets as part of landing parties.

[citation needed] The core rules were a revised version of the earlier Heritage Star Trek RPG (Star Trek: Adventure Gaming in the Final Frontier), with extra material on skills, Star Fleet organization, ranks and uniforms, plus updates from the two movies, but with specific character references omitted to produce a generic design that included terms like "Vulcan Science Officer", "Klingon Soldier", but left in Trek-specific terms like Phaser and Warp Drive (though the Klingon, Romulan and Kzinti sample characters retained their original names).

"The Landing Party" contains rules for adventures by the starship crew who have left the spaceship to explore the surface of an unexplored and usually primitive planet.

The Basic Game covers the mechanics of individual player Character Generation, Learning which means coming to understand new phenomena as they were presented by the Mission Master (Starfleet Voyages terminology for the GM), Psionics, Saving Rolls, the Transporter, Combat Rules, Movement, Hand-to-Hand and Ranged combat, Recordkeeping, and a simplified characteristic system for generating NPC monster stats.

These include the captain of a starship, his fellow bridge officers, and other crew members who have crash-landed their shuttle on a mysterious planet.

The Advanced Game began with another scenario which has the intrepid crew members and officers investigate an ancient base of the long-gone Slaver Empire.

When generating a character a player rolls 3D6 for Strength, Dexterity, Luck, Mentality, Charisma, and Constitution.

The list concluded with a set of randomly entered tables for the creation of new monsters with which to entertain the players.

Finally, "The Landing Party" concluded with a more complete combat system that included many possible situational modifiers and an extensive weapons effects list.

Each starfaring race may use only certain specific ship designs, and these were rated for power, speed capability, defensive screens, and weapons.

There is usually not enough power to move at top speed with full defensive screens while shooting every weapon on board.

When warships shoot weapons, the players roll percentile dice and modify the results to determine damage.
