What is Star Trek Adventures?
Star Trek Adventures is a tabletop role-playing game (RPG) published by Modiphius Entertainment, designed to immerse players in the iconic Star Trek universe. Unlike many RPGs focused on high-ranking officers and grand galactic conflicts, Star Trek Adventures uniquely emphasizes collaborative storytelling and character-driven narratives. It allows players to create their own Starfleet officers or explore roles beyond the Federation, experiencing life aboard a starship or on distant planets.
The game utilizes a “Narrative Dice Pool” system, where players build pools of dice based on their skills and attributes, adding drama and unpredictability to every action. This system encourages creative problem-solving and teamwork. The core rulebook provides everything needed to begin playing, including character creation rules, ship design guidelines, and a wealth of background information on the Star Trek universe.
Crucially, the game’s flexibility allows for seamless integration of content from various Star Trek series, including the comedic adventures found within Star Trek: Lower Decks, making the Lower Decks supplement a natural and exciting addition to the game.
The Significance of the Lower Decks Supplement
The Star Trek: Lower Decks Campaign Guide supplement is significant because it brings the unique comedic tone and relatable characters of the animated series into the Star Trek Adventures RPG. Previously, capturing the show’s humor within the game’s framework proved challenging. This supplement directly addresses that, providing tools and guidance for Game Masters (GMs) to emulate the show’s distinctive style.
It’s more than just character stats; it’s about embracing the “underdog” perspective and the everyday struggles of lower-ranking Starfleet officers. The supplement allows players to experience adventures that aren’t necessarily about saving the galaxy, but about navigating the complexities of shipboard life and quirky alien encounters.
Furthermore, it expands the game’s universe by introducing the U.S.S. Cerritos and its crew, offering fresh campaign possibilities and a different flavor of Star Trek storytelling. It’s a comedic and fun addition!

Using the Lower Decks Supplement in Your Game
The Lower Decks PDF unlocks comedic campaign ideas and allows adaptation of the Cerritos’ setting. Incorporate the show’s humor for unique RPG sessions!
Campaign Ideas Inspired by the Series
The Star Trek: Lower Decks supplement provides fertile ground for campaign concepts mirroring the show’s blend of Starfleet protocol and chaotic mishaps. Consider a mission where the Cerritos is tasked with a seemingly simple delivery, only for Ensign Mariner’s “creative” solutions to escalate the situation into a full-blown intergalactic incident.
Alternatively, a campaign could center around a series of increasingly bizarre first contacts, forcing the crew to navigate cultural misunderstandings with a healthy dose of awkwardness. Perhaps the players must mediate a dispute between two alien races over the proper way to consume replicated plomeek soup!
Another idea involves a malfunctioning Starfleet regulation that throws the Cerritos into disarray, requiring the ensigns to circumvent bureaucracy and save the day. Lean into the show’s themes of underappreciated crew members proving their worth, and don’t be afraid to embrace the absurd!
Remember to emphasize character interactions and comedic timing, mirroring the dynamic between Mariner, Boimler, Tendi, and Rutherford.
Adapting the Cerritos’ Setting for RPG Sessions
The U.S.S. Cerritos, a California-class starship, offers a unique RPG setting – a support vessel focused on second contact and minor diplomatic missions. Unlike flagship vessels, the Cerritos is delightfully…unremarkable, providing ample opportunities for low-stakes, character-driven stories.
Emphasize the ship’s slightly rundown aesthetic and the crew’s resourcefulness in making do with limited resources. Incorporate the Cerritos’ quirky departments, like the badge office and the replicated food replicator malfunctions, into your adventures.
Don’t shy away from portraying the ship’s less glamorous duties – transporting space garbage, mediating minor disputes, or cataloging obscure alien artifacts. These mundane tasks can be surprisingly engaging when viewed through the lens of the Lower Decks’ comedic style.
Remember that the Cerritos is a working starship, so include background details like ongoing maintenance, crew routines, and the occasional interdepartmental rivalry to create a believable and immersive environment.
Incorporating the Show’s Humor into Gameplay
To truly capture the spirit of Lower Decks, embrace comedic timing and character quirks during RPG sessions. Encourage players to lean into their characters’ flaws and insecurities, and reward creative solutions that prioritize humor over strict adherence to Starfleet regulations.
Don’t be afraid to introduce absurd situations and unexpected complications. A malfunctioning transporter, a rogue holographic program, or a diplomatic incident caused by a cultural misunderstanding can all provide fertile ground for comedic roleplaying.
Utilize the “yes, and…” principle of improvisational comedy, building upon player suggestions and escalating the absurdity of each scene. Allow failures to be funny rather than frustrating, and emphasize the characters’ reactions to chaotic events.
Remember that the humor in Lower Decks often stems from the contrast between the characters’ aspirations and their everyday realities. Play with this dynamic by presenting players with challenges that are both important and hilariously mundane.
