Star Trek Adventures

Star Trek Adventures is one of the better licensed TTRPGs for groups that actually want to play Star Trek rather than just borrow its uniforms and ship names. It is strongest when your table wants exploration, diplomacy, scientific problem-solving, bridge teamwork, and ethical pressure to matter as much as combat. It is a weaker fit for groups chasing outlaw sandbox play, combat-first optimization, or rules that stay almost invisible once the scene starts.

The current game line is centered on the 2024 second edition core rulebook, but the broader line is now large enough that you can enter through the free quickstart, the Starter Set, or the full official Star Trek Adventures collection depending on how committed your group already is.

What the game is

Star Trek Adventures is Modiphius Entertainment's officially licensed Star Trek tabletop roleplaying game. Its default mode is a crew of officers, specialists, and supporting characters tackling missions aboard a starship or at the edge of Federation space, with the rules tuned for away missions, bridge scenes, negotiations, scientific mysteries, and occasional firefights rather than constant tactical war-gaming.

The line uses Modiphius' 2d20 engine, but it is not just a generic science-fiction skin. The game is built to recreate the rhythm of a Star Trek episode: the crew identifies a problem, splits responsibility across departments and stations, pushes through complications under pressure, and then lives with the consequences of the principles it chose to uphold.

Publication history and editions

The first core rulebook released in 2017 and established the line as a Federation-focused 2d20 game with a large supplement and adventure bench. The current core line shifted to second edition in 2024, with the standard hardcover core book published on May 1, 2024. Modiphius positions that book as an updated ruleset rather than a total reboot, and the surrounding support line keeps that same approach.

That matters because the line did not reset to a blank slate. Modiphius' own support articles say the game now includes well over 100 standalone adventures and more than 300 single-page mission briefs, and that most first-edition material needs only minor conversion for second-edition use. If you are looking for a long-running licensed game with real adventure support instead of a single core-book promise, this is one of the more convincing cases in the hobby.

What you need to play

The lowest-friction entry point is the Second Edition Quickstart Guide PDF. The current product page describes it as a free second-edition quickstart with the three-act introductory scenario The Celestial Algorithm plus seven pregenerated characters and the U.S.S. Challenger.

If your group wants a boxed onboarding path, the Second Edition Starter Set is a good next step. Modiphius says it includes a 60-page three-part campaign called Infinite Combinations, a 48-page rules booklet, reference cards, tokens, dice, pregenerated characters, and a ship sheet, which makes it a genuine teach-through-play product rather than a sampler with no runway.

If you already know your group wants the full game, go straight to the Second Edition Core Rulebook. It is the complete reference for character creation, starship creation, GM procedure, adversaries, and the broader eras of play. You can then expand into the current support line, which as of July 8, 2026 includes the Game Toolkit, Exploration Guide, Technical Manual, Species Sourcebook, Allies and Adversaries Sourcebook, and 23rd Century Campaign Guide.

Major supplements, campaigns, and adjacent products

The support line is unusually practical for campaign play. Modiphius' February 18, 2025 article on using the Starter Set with published adventures says the line includes well over 100 standalone adventures and 300-plus mission briefs, and it specifically calls out the continuing usefulness of earlier campaign products with only minor second-edition conversion. That means the official catalog is not just lore books and accessories; it includes a real mission pipeline.

If you want solo or co-op Star Trek play, the adjacent product to know is Captain's Log. It is a standalone game rather than a required add-on, but it uses a streamlined form of the same overall design language and gives the line a practical off-ramp for players who cannot reliably gather a full crew.

Core rules and play structure

The heart of the game is straightforward once the table internalizes the resource loop. Characters attempt tasks by combining an attribute and a discipline, rolling d20s, and counting successes against a difficulty. Extra successes become Momentum, which the group can spend immediately or bank for later advantages such as better information, faster progress, or stronger follow-through. The GM uses Threat as the mirror pressure valve: if players buy extra dice, push their luck, or hand the game complications, the GM gains currency to intensify danger or escalate the next scene.

The other major pillar is Determination, which ties characters' Values to moments of decisive action. In practice that means the game is not just about whether a scan succeeds or a phaser hits. It is also about whether a captain, scientist, or engineer is willing to lean on what they believe when the mission turns complicated. The result is a ruleset that rewards competent crew problem-solving without abandoning dramatic character choices.

Characters, roles, and advancement

Star Trek Adventures works best when the group treats the ship and crew as the real party structure. Bridge roles, department specialties, supporting characters, and away-team assignments all help everyone feel useful in different phases of the mission. You are not simply choosing a combat build and waiting for initiative; you are choosing how your officer contributes to command decisions, technical solutions, first contact, emergencies, and the social temperature of the table.

Character growth is better at deepening a crew than at chasing endless vertical power. Advancement exists, but the larger appeal is the continuing history of the ship, the weight of prior missions, and the way recurring supporting cast, rivals, and principles change the next decision. If your group wants ever-larger damage numbers or build trees to be the whole campaign reward, other science-fiction games do that more directly.

Signature mechanics

The distinct feel comes from how the game stacks several procedures on top of one another without becoming especially crunchy. Momentum and Threat create a visible push-pull economy. Values and Determination give personal beliefs mechanical weight. Traits let the fiction itself matter instead of reducing everything to a flat modifier. Supporting characters keep away missions and crew-scale play from collapsing into "only the main cast matters." Starship scenes, meanwhile, let bridge positions feel like jobs with different responsibilities instead of a single shared attack roll.

Those pieces are why the game tends to feel like Star Trek when it is running well. Problems unfold across science, command, medical, security, and engineering rather than only across range bands and hit points. Even when the crew is in danger, the question is often "how do we solve this?" before it is "how do we kill it?"

What play feels like

At the table, Star Trek Adventures usually feels like a mission-focused ensemble show. A typical session moves from briefing to investigation, from away-team complication to bridge response, then into some combination of negotiation, technical improvisation, moral choice, or controlled crisis. Combat exists, but it is rarely the only payoff scene unless the GM steers the game that way.

This is also a more optimistic science-fiction game than many of its neighbors. Even when the setting is under strain or the crew is operating in a war-era frame, the default play identity is still curious, problem-solving, and duty-driven rather than nihilistic or mercenary. That tone is one of the line's biggest strengths, but it does require player buy-in.

Running the game

GM load is moderate rather than trivial. You need enough prep to stage the mission problem, understand likely departments and obstacles, and keep the crew moving when they split attention between ship and away team. The good news is that the line offers a lot of official scaffolding, from quickstarts and starter material to mission briefs and campaign products. The harder part is judging when to spend Threat, when to make a complication interesting instead of punitive, and how hard to lean into Star Trek ethics instead of generic adventure plotting.

Groups that thrive here usually have a GM who enjoys adjudicating consequences, scene framing, and institutional pressure more than detailed tactical map play. If that is your instinct, the game gives you plenty to work with. If you mostly want skirmish design and tightly balanced fight math, you may feel like the engine keeps pointing you back toward story logic and crew procedure.

Campaign fit

Campaign play is where Star Trek Adventures makes the strongest long-term case for itself. Ships, crews, mission briefs, recurring NPCs, and era-specific tensions all create natural continuity. The official support line reinforces that with both fresh second-edition books and a large backlog of older adventures that remain usable with light effort.

It can run one-shots, especially through the quickstart or curated mission briefs, but it shines more brightly when the crew matters from week to week. A returning captain's reputation, an engineer's hard-won workaround, a science officer's first-contact mistake, or a diplomatic compromise that comes back three sessions later all feel more rewarding in campaign play than in a disposable convention scenario.

Reception and awards

Reception has been strongest where it most needs to be: in whether it feels like Star Trek at the table. The original line earned a 2018 ENNIE Silver award for Best Rules, and the Collector's Edition Core Rulebook earned ENNIE Silver for Production Values that same year. More recent second-edition review coverage has generally praised the cleaner presentation, the easier onboarding relative to first edition, and the way the game captures the rhythm of a Star Trek episode rather than merely decorating a generic engine.

The usual caveat is also consistent: this is still a 2d20 game with visible meta-currency and scene-facing adjudication. Groups that dislike shared resource pools, narrative permissions, or values-driven spotlight mechanics may bounce off it even if they love the license. Put differently, you should choose it because you want Star Trek and the way this game delivers Star Trek, not because you assume any licensed game will do.

Where it is strongest

• It turns bridge roles, away teams, diplomacy, and scientific problem-solving into the core loop instead of treating them as flavor text around combat.
• The official line is deep enough to support real campaigns, not just a hopeful promise that the GM will invent everything after the core book.
• Second edition appears easier to teach and cleaner to reference than first edition while staying recognizably compatible with the line's broader material.
• It offers a rare optimistic science-fiction campaign frame that still generates pressure, stakes, and hard choices.

Where it can frustrate groups

• Players who want combat-first space action or heavy tactical optimization may find too much of the game pointed toward diplomacy, procedure, and consequence instead.
• Tables that dislike Momentum, Threat, and other visible meta-currency may never quite warm to the engine even if they like the setting.
• The game works best when players accept mission structure and institutional duty; it is a weaker fit for pure outlaw freedom or self-directed trader sandboxing.
• Non-fans can absolutely play it, but a table with no interest in Star Trek's tone, values, or recurring problem types will probably get more mileage from a different space TTRPG.

Content and safety notes

The line can move through war stories, first-contact disasters, body horror, authoritarian empires, assimilation imagery, ethical triage, and command hierarchy depending on the era and mission material you use. None of that makes the game unusually extreme by horror standards, but it does mean the table should align on whether it wants optimistic exploration, frontier danger, wartime pressure, or political tension before a campaign starts.

Best starting path

Start with the free quickstart if you want to test the table rhythm cheaply. Choose the Starter Set if your group learns best from a boxed teach-through-play product. Move straight to the Second Edition Core Rulebook if you already know you want a longer campaign. If your main challenge is scheduling rather than interest, look at Captain's Log as the companion or alternative path.
