The 2d20 System Explained
The 2d20 System, at the heart of Star Trek Adventures, is a streamlined and narrative-focused roleplaying mechanic. Players roll two twenty-sided dice (2d20) and add relevant skills and modifiers to the result. The goal isn’t simply to succeed or fail, but to determine the quality of the outcome. Results fall into ranges, from Dramatic Failures to Exceptional Successes, shaping the story in dynamic ways.
The system emphasizes collaborative storytelling. The Game Master (GM) doesn’t dictate events, but rather reacts to player choices and dice rolls, building the narrative together. Difficulty is adjusted by setting a target number, and exceeding it determines the degree of success. The PDF rulebooks provide a detailed breakdown of the system, including character creation, skill lists, and combat rules.
Success with Degrees allows for complications or advantages, adding layers of depth to every action. This system encourages players to embrace risk and creativity, knowing that even failures can lead to compelling story developments. It’s a system designed to capture the spirit of Star Trek – exploration, problem-solving, and the unpredictable nature of the final frontier.
Focus on Lower Decks Integration
This Star Trek Adventures expansion dives deep into the comedic world of Lower Decks, offering a unique roleplaying experience. The PDF materials are specifically designed to capture the show’s irreverent humor and focus on the often-overlooked crew members of Starfleet. Expect scenarios centered around secondary missions, bureaucratic mishaps, and the everyday challenges of life aboard a California-class starship.
The integration isn’t just thematic; the ruleset supports the show’s style. Crisis Management and Direct Tasks become crucial, reflecting the Cerritos’ constant state of low-level emergencies. Character creation encourages embracing quirks and flaws, mirroring the endearing imperfections of the Lower Decks cast.
Players can expect encounters with familiar faces like Captain Freeman, Commander Riker, and even the ever-frustrated Admiral Kren. The expansion provides tools to emulate the show’s fast-paced dialogue and satirical tone, ensuring a truly authentic Lower Decks roleplaying experience. Prepare for a hilarious and unpredictable adventure!
Core Rulebook & Quickstart Guide
The Star Trek Adventures core rulebook, available as a PDF download, provides the foundational rules for playing in the 2d20 System. It details character creation, skill resolution, and the intricacies of starship combat. However, for newcomers eager to jump into the Lower Decks universe, the included Quickstart Guide is the perfect entry point.
This condensed version of the ruleset streamlines gameplay, focusing on the essentials needed to run “The Celestial Algorithm,” a thrilling introductory adventure. The Quickstart Guide simplifies character creation, offering pre-generated characters ready to explore the Cerritos and its surrounding sectors. It’s designed to get players engaged quickly, without getting bogged down in complex rules.
Both the core rulebook and Quickstart Guide emphasize narrative storytelling and collaborative world-building. The PDF format allows for easy searching and referencing during gameplay, ensuring a smooth and enjoyable experience for both Gamemasters and players. Prepare for discovery and adversity!

This scenario is specifically designed to immerse players in the quirky and often chaotic world of the U.S.S. Cerritos. It’s a perfect starting point for both newcomers to the Lower Decks series and veterans of the Star Trek Adventures roleplaying game.
The adventure throws the crew into a seemingly routine mission that quickly spirals into a bizarre investigation involving a mysterious celestial phenomenon.

Key Characters from Lower Decks in STA
The Star Trek Adventures: Lower Decks adaptation brings the beloved crew of the U.S.S. Cerritos to life! Character options, detailed within the core rulebook and supplemental PDF materials, allow players to embody Beckett Mariner, Brad Boimler, D’Vana Tendi, and Sam Rutherford. Each character features unique abilities and motivations reflecting their on-screen personalities.
Expect pre-generated character sheets and guidance on roleplaying these iconic individuals, capturing their quirks and strengths. The game emphasizes the dynamic between these lower deckers, encouraging players to embrace the comedic and often awkward situations they find themselves in. The PDF resources provide insights into their backgrounds and relationships, aiding in immersive roleplaying.
Beyond the core four, the system also supports the creation of characters inspired by supporting cast members; UniVersus cards, some with lenticular treatments showcasing beaming up to the Cerritos, further enhance character representation. Prepare to navigate Starfleet regulations (or disregard them entirely, like Mariner!) within the STA framework.
Admiral Kren and Supporting Characters
Admiral Kren, a recurring figure in Lower Decks, is a significant presence in Star Trek Adventures campaigns. The supplemental PDF materials detail Kren’s stats, motivations, and potential role as an antagonist or reluctant ally. Expect a character driven by bureaucratic efficiency and a… unique perspective on Starfleet protocol. His interactions with the Cerritos crew provide ample opportunities for comedic conflict and challenging scenarios.
Beyond Kren, the game incorporates other supporting characters from the series, such as Captain Freeman, Lieutenant Shaxs, and Doctor T’Ana. The PDF resources offer guidelines for portraying these characters as NPCs, complete with personality traits and potential plot hooks. Players might find themselves navigating Freeman’s ambitious goals or dealing with Shaxs’s gruff demeanor.
The system allows GMs to create original characters inspired by the show’s universe, expanding the roster of potential allies and adversaries. Expect detailed notes on integrating these characters into storylines, ensuring a cohesive and immersive Lower Decks experience.
Captain Freeman’s Role in Campaigns
Captain Carol Freeman is a central figure in Star Trek Adventures: Lower Decks campaigns, and the supplemental PDF materials provide extensive guidance on incorporating her into gameplay. She’s not merely a background character; Freeman’s ambition, competence, and occasional exasperation with her crew drive many potential storylines.
The PDF details how to portray Freeman as both a commanding officer and a complex individual. GMs can utilize her desire for recognition and promotion to create compelling missions, often involving navigating Starfleet bureaucracy or undertaking seemingly insignificant assignments with hidden importance. Expect scenarios where the crew must balance Freeman’s expectations with the realities of their often-chaotic duties.
Furthermore, the guide explores Freeman’s relationships with the Cerritos crew, offering insights into how she interacts with each character. This allows for personalized interactions and opportunities for players to influence her decisions. The PDF also includes suggestions for incorporating her backstory and motivations into larger campaign arcs.
The U.S.S. Cerritos as a Playable Starship
The U.S.S. Cerritos, affectionately known as the “Least Important Starship,” is fully detailed as a playable vessel within the Star Trek Adventures: Lower Decks PDF. Unlike the sleek flagships of Starfleet, the Cerritos is a California-class support ship, emphasizing its unique capabilities and limitations.
The PDF provides comprehensive starship statistics, including hull integrity, shield strength, and weapon systems, reflecting its support role. Detailed deck plans are included, highlighting key locations like the bridge, engineering, and the often-troubled transporter room. Special attention is given to the Cerritos’ secondary missions – diplomatic support, resource transport, and, of course, second contact.
GMs can leverage the Cerritos’ quirks and less-than-glamorous assignments to create engaging scenarios. Expect missions involving malfunctioning equipment, awkward diplomatic encounters, and the constant struggle to prove the ship’s worth. The PDF also includes rules for managing the Cerritos’ unique crew complement and navigating its often-chaotic internal dynamics.
Gameplay Mechanics: Crisis Management
Star Trek Adventures: Lower Decks, detailed in its PDF format, heavily emphasizes “Crisis Management” as a core gameplay mechanic, mirroring the hectic nature of life aboard the U.S.S. Cerritos. This system allows players to address immediate, pressing issues that arise during missions, often simultaneously with larger objectives.
The PDF outlines how crises are introduced – from malfunctioning warp drives to unexpected alien encounters – and how players can utilize their skills and resources to mitigate the damage. The “Direct Task” ability, found on page 173 of the core rulebook (referenced in the PDF), is crucial; characters can utilize it twice per scene during crises, showcasing their quick thinking and adaptability.
Crisis Management isn’t simply about skill checks; it’s about prioritization and teamwork. Players must decide which crises demand immediate attention and coordinate their efforts to prevent cascading failures. The PDF provides tools for GMs to dynamically adjust crisis severity and consequences, ensuring a challenging and unpredictable gameplay experience, perfectly capturing the spirit of Lower Decks.
Direct Task Utilization in Lower Decks Scenarios
The Star Trek Adventures: Lower Decks PDF highlights the “Direct Task” as a pivotal mechanic for embodying the show’s fast-paced, problem-solving ethos. Unlike traditional skill challenges, Direct Tasks allow characters to immediately address a situation using a relevant skill, bypassing lengthy roleplaying if desired – a nod to the efficient (and sometimes chaotic) nature of Cerritos operations.
The PDF details that in Lower Decks scenarios, the Direct Task isn’t just a shortcut; it’s often expected. Characters frequently face multiple urgent issues simultaneously, demanding swift action. The rule allowing twice per scene usage during crises (as outlined in the core rulebook, page 173, within the PDF) reflects this heightened pressure.
GMs are encouraged to use Direct Tasks to represent quick repairs, improvised solutions, or on-the-fly adjustments. This mechanic streamlines gameplay, keeping the focus on dynamic situations and comedic timing, mirroring the show’s blend of action and humor. The PDF provides examples tailored to Lower Decks, showcasing how to effectively integrate Direct Tasks into scenarios.
Personal Combat Rules Overview
The Star Trek Adventures: Lower Decks PDF details a streamlined personal combat system, reflecting the often-unconventional and slapstick nature of conflicts encountered aboard the U.S.S. Cerritos. While adhering to the core 2d20 system, the PDF emphasizes narrative impact over meticulous tactical detail, prioritizing speed and comedic potential.
Combat revolves around opposed skill checks – typically Engineering, Security, or Medicine – determining success in actions like disarming, dodging, or delivering a stunning blow. The PDF clarifies that phaser use is often a last resort, with characters frequently relying on improvised weaponry or environmental hazards, mirroring the show’s resourceful (and often clumsy) crew.
Damage is abstracted, focusing on “Stress” rather than hit points, representing physical and mental strain. The PDF includes rules for complications, such as malfunctioning equipment or unexpected environmental factors, adding a layer of unpredictable chaos. GMs are encouraged to embrace creative solutions and prioritize entertaining outcomes over strict adherence to combat protocols, as detailed within the PDF’s guidelines.
Starship Combat Rules Overview
The Star Trek Adventures: Lower Decks PDF presents a starship combat system designed to capture the frantic, often-underprepared nature of the U.S.S. Cerritos’ encounters. While utilizing the core 2d20 system, the PDF emphasizes quick resolution and narrative consequences over complex tactical simulations.
Combat is structured around broad actions – maneuvering, targeting, attacking, and defending – resolved through opposed skill checks involving Engineering, Tactics, and Command. The PDF highlights the importance of “Crisis Management,” allowing players to mitigate damage or exploit enemy weaknesses through clever improvisation, a hallmark of the series.
Damage is tracked through ship systems, with critical hits potentially causing cascading failures and comedic complications. The PDF includes rules for unique ship abilities and tactical maneuvers, reflecting the Cerritos’ aging technology and unconventional crew. GMs are encouraged to prioritize dramatic tension and humorous outcomes, embracing the ship’s tendency to stumble into (and occasionally out of) dangerous situations, as detailed in the PDF.
Tactical Decision Making in STA
The Star Trek Adventures (STA) system, as detailed in the Lower Decks PDF, emphasizes tactical choices beyond simple skill checks. Players aren’t just rolling dice; they’re navigating chaotic situations demanding quick thinking, mirroring the Cerritos’ often-improvised solutions. The PDF stresses that success isn’t always about optimal strategy, but about creatively exploiting opportunities.
“Direct Tasks,” outlined in the core rulebook (referenced in the PDF), allow characters to bypass standard checks for immediate action, crucial during crises. The PDF encourages GMs to reward inventive problem-solving, even if it bends the rules slightly, fostering a dynamic and unpredictable gameplay experience.
Tactical decisions extend to both personal combat and starship engagements. The PDF highlights the importance of considering environmental factors, enemy weaknesses, and the Cerritos’ limitations. Players must weigh risks, prioritize objectives, and adapt to unforeseen circumstances, embracing the show’s blend of competence and comical mishaps. The PDF provides tools for GMs to create challenging scenarios that demand clever tactical thinking.
The Role of Humor and Satire in Lower Decks Games
Star Trek Adventures: Lower Decks, as presented in the downloadable PDF, isn’t just about replicating Starfleet missions; it’s about embodying the show’s unique comedic tone. The PDF encourages players and Game Masters (GMs) alike to embrace the satire and absurdity inherent in Lower Decks.
Successful campaigns will lean into the characters’ flaws, the Cerritos’ second-tier status, and the often-bureaucratic nature of Starfleet. The PDF suggests incorporating running gags, awkward social interactions, and escalating mishaps. Don’t shy away from portraying characters making questionable decisions or facing hilariously mundane problems.
The PDF emphasizes that humor shouldn’t undermine the stakes, but rather enhance them. Even amidst chaos, characters should still strive to uphold Starfleet values (however clumsily). Encourage players to roleplay with exaggerated personalities and witty banter, capturing the spirit of the show. The PDF provides guidance on balancing serious moments with comedic relief, creating a truly authentic Lower Decks experience.
Pakleds as Antagonists
The PDF version of Star Trek Adventures: Lower Decks highlights the Pakleds as ideal antagonists, perfectly mirroring the show’s penchant for underestimating threats. These scavenging, technologically inept beings provide ample opportunities for comedic conflict and surprisingly challenging encounters.
The PDF details how to portray Pakleds as more than just simple villains. Their obsession with “useful things” can lead to bizarre scenarios, forcing the Cerritos crew to negotiate, outsmart, or simply evade them. GMs are encouraged to emphasize the Pakleds’ broken speech patterns and illogical demands, adding to the humor.
The PDF offers adventure hooks centered around Pakled salvage operations disrupting Starfleet activities or the Pakleds attempting to “improve” their technology with stolen components. Remember Admiral Kren’s exasperation with them! The PDF suggests utilizing the 2d20 system to represent the Pakleds’ unpredictable behavior and surprisingly resilient ships, creating dynamic and engaging challenges for players.
Kzinti and Aurelians in STA Campaigns
The Star Trek Adventures: Lower Decks PDF expands campaign possibilities by incorporating the Kzinti and Aurelians, species recently highlighted in modern Star Trek series. These additions enrich the game’s universe and offer unique roleplaying opportunities.
The PDF provides background information on both species, drawing from their appearances in Picard and Prodigy. Kzinti, known for their warrior culture and historical conflict with the Federation, can serve as formidable adversaries or complex allies. Aurelians, with their unique physiology and philosophical outlook, present intriguing diplomatic challenges.
GMs can utilize the PDF’s guidelines to create scenarios involving Kzinti raiding parties, Aurelian exploration missions, or even joint ventures with these species. The PDF suggests incorporating elements of political intrigue and cultural misunderstanding, mirroring the nuanced portrayals seen in contemporary Star Trek. The 2d20 system allows for dynamic encounters, reflecting the Kzinti’s tactical prowess and the Aurelians’ enigmatic nature.
UniVersus Cards & Lenticular Treatments
The Star Trek Adventures: Lower Decks PDF release introduces a stunning collectible element: UniVersus cards! Each deck contains character cards, enhancing roleplaying and character tracking. But these aren’t ordinary cards – they feature a unique lenticular treatment!
Specifically, one character card per deck showcases a captivating lenticular effect, visually depicting the character beaming up to the U.S.S. Cerritos.
