Mindjammer

Mothership is an action-packed mixture of sci-fi and horror themes, combined into a streamlined gaming system about surviving in the cold, deadly vacuum of space while everything around you is trying to kill you. All at the same time as you are fighting (or fleeing from) alien creatures who aren't there to make any new friends. Chaos. It was published by Tuesday Knight Games and released in 2024.  It is a survival horror system designed for one-shots and campaigns, inspired by classics like Alien, Event Horizon, and Pandorum. Famous for its streamlined ruleset and award-winning graphic design that prioritizes ease of use at the table. The game, at the same time simplistic and streamlined in design, will challenge the characters at all times, allowing the game to focus on the storytelling and less on having complicated rules. The system it is inspired by is Old School Renaissance Description In Mothership, players take on the roles of blue collar workers in space, such as Teamsters, Scientists, Androids, and Marines. You are not powerful or heroic soldiers; you are vulnerable humans trapped in high pressure environments with alien monsters, failing life support systems and the crushing weight of corporate greed. The game is designed to be fast-paced and unforgiving, where the primary goal is not to win, but often enough - to survive. System Overview & Key Features d100 Percentile Resolution In the core of the game system is the d100 percentile system. Roll two d10 dice and get a number from 00 to 99. Success means rolling a lower result than your character's appropriate stat or skill for the task. Rolling a double, like 11, 22, or 33, is considered a critical success if it succeeds or a critical failure if it fails. Rolling low is the target for survival. Stress and Panic As characters encounter horrors or suffer trauma, they accumulate Stress. When a character experiences a terrifying event or rolls a critical failure they must make a Panic Check. The more Stress they have, the more likely they are to suffer a catastrophic mental breakdown, ranging from a heart attack to a violent psychotic break. The Save System Instead of a long list of saving throws, characters have four primary Saves: Sanity, Fear, Body, and Armor. These are used to resist different types of potential trauma. Fear saves are rolled to keep your cool under pressure, while Sanity saves represent your ability to process alien truths without losing your mind (think lovecraftian horrors). Class Based Skills The game features four distinct classes. Marines are obviously combat focused, Teamsters are pilots and laborers, Scientists are experts in medicine and biology, and Androids are cold calculating, yet efficient machines. Each class has it's unique starting stats and specific triggers for when they gain or lose Stress, which is based on their personality. Lethal Combat and Healing Combat is extremely dangerous and often a last resort. Weapons are likely to deal potentially excessive damage when compared to a character's total healthpool. Healing will be slow and require resources that are hard to come by in the middle of the constant crisis, making every injury feel like a significant threat to the character's chances of making it out alive. Deadly Ship-to-Ship Combat The game includes a streamlined system for starship encounters. Ships have their own stats and modules that are likely to be damaged during a fight. Players must work together to manage various roles and stations, like Engineering or Piloting, to keep the ship's hull from breaching while under fire or fleeing from cosmic anomalies.

Traveller 2E is a sci-fi tabletop roleplaying game system, that was published in 2016 and updated in 2022, by Mongoose Publishing. It involves the characters adventuring through star systems, engaging in (space) exploration and engaging in battles both on ground and in space. The system it directly evolved from is classic Traveller (1977) Description The characers in Traveller can be humans, robots, aliens or of a genetically engineered species. Each character is distinguished by their occupation - whether they are a civilian, military, a noble, a young cadet or a veteran. Each type comes with their own strengths and weaknesses. To further expand on the sci-fi aspect of the game, some characters are prone to extra-sensory abilities, such as telekinesis, telepathy and others. System Overview & Key Features Lifepath Character Creation When creating their character, players roll to determine their character's background, education, and career history. Characters will acquire skills, allies, enemies and physical injuries. No Classes or Levels Characters do not have traditional classes, and they do not gain experience points to level up. Progression is entirely material and narrative. Characters improve by acquiring better gear, installing cybernetics, buying larger starships, and finding lucrative trade routes. The Trade and Commerce System A massive part of the game involves interstellar economics. The rules provide deep, robust systems for buying speculative cargo on one planet and selling it at a profit on another. Players must factor in fuel costs, jump drive maintenance, and life support while managing their massive starship mortgage. Lethal Combat Gunfights are incredibly dangerous as the characters have very low health pools. These are directly tied to their physical attributes like Endurance, Dexterity, and Strength. A single shot from a laser rifle can instantly incapacitate or kill a character, making armor and cover absolute necessities. Hex Crawling and Subsectors The game provides incredible tools for the Game Master to procedurally generate entire sectors of space. Using a blank hex map and the core rulebook, you can roll up planetary environments, government types, law levels, and starport qualities to create a completely unique sandbox galaxy.

Salvage Union is a RPG set in a Post-Apoc world where MegaCorps rules pockets of civilization and nomads on giant 'Crawlers' comb the wastes for 'salvage'. Players are part of the 'Salvage Union', on one of these roaming Crawlers and deploy out in jury-rigged Mechs to collect salvage and investigate their ruined world. Description Playing Salvage Union means playing a crew of salvager mech pilots living aboard a massive, mobile home base called a Union Crawler, scavenging a corporate-ravaged wasteland for scrap to keep their community alive. Beyond raiders and rival scavengers, threats include monstrous Bio-Titans, alien Meld, and the Corpos who still control most of the world's remaining resources. Much of the game's appeal comes from its two-layered loop: narrative exploration and salvaging runs outside the mech, and tactical, resource-managed mech combat once things go loud, tied together by a deep crafting system that lets pilots build and refit their machines from scavenged parts between missions.

Obsidian is a free, locally-stored Markdown note-taking application that the TTRPG community has widely adopted as a campaign wiki, session planner, and lore database. Originally designed as a personal knowledge management tool, it stores everything as plain text files on your own machine with no subscription required. Description Unlike purpose-built platforms such as World Anvil, Obsidian was not designed with TTRPGs in mind, which means it arrives without templates, stat block support, or any TTRPG-specific structure out of the box. GMs who want those features need to install and configure community plugins themselves, which carries a steeper setup cost than dedicated alternatives. For those comfortable with that process, however, the result is a highly customizable system with no ongoing fees and no vendor lock-in. A thriving plugin ecosystem has filled most of the gaps, and the tool has become a genuine alternative to subscription-based worldbuilding platforms for technically comfortable Game Masters. The plugin ecosystem extends well beyond what is listed here, with community tools covering everything from database-style note querying and cross-device sync to interactive maps and combat automation. A full directory is available at community plugins.

Stars Without Number is a sandbox science fiction tabletop role-playing game designed by Kevin Crawford and published by Sine Nomine Publishing. Originally released in 2010, followed by an extensively expanded and restructured Revised Edition in 2017, the game is a prominent fixture of the Old School Renaissance (OSR) movement. It is structurally engineered to merge the lightweight tactical framework of early fantasy role-playing systems with exhaustive, modular sci-fi sandbox generation toolkits. Description Stars Without Number takes place in the year 3200, centuries after the tragic collapse of the Second Terran Mandate. The human galaxy was once interconnected by instantaneous jump gates and protected by a core of psychic navigators, until an evolutionary psychic catastrophe known as "The Scream" drove every psychic in existence instantly insane or dead. The sudden collapse of interstellar transit triggered a multi-century dark age of isolation known as the Silence. In the modern setting, fractured sectors of space are finally rediscovering faster-than-light spike drives and exploring a fragmented universe. Players navigate this dangerous frontier as spacers, scavengers, mercenaries, or rogue psychics, operating in a cosmos characterized by corporate espionage, lost pre-collapse technology, and shifting planetary regimes.

The story takes place in the near-future of 2045 following the events of the Fourth Corporate War. The period for the game's storyline is named the "Time of the Red" due to atmospheric pollution. The system it directly evolved from is Cyberpunk 2020 Description Players in the game are referred to as "Edgerunners". They are mercenaries, criminals, and specialists living in the metropolis of Night City. The games focus on completing jobs and surviving in a megacorporations and street gangs controlled society. As the global supply chain has collapsed, resources are scarce and players must often rely on black-market brokers, known as Fixers, to find their equipment, weapons, and armor. Cybernetic body modifications are a recurring topic in the game, with the emphasis on the risks of enhancing one's body and mind with. System Overview & Key Features Core Dice Mechanic (Interlock System) The game uses a Interlock System. An action's success is determined with a a ten-sided die (d10) and adding the relevant Statistic and Skill rating. The total is compared against a Difficulty Value (DV). Lifepath Generation When creating a character, the player can either roll or manually pick various options from the "Lifepath" tables. The choices made will define the character's cultural background, their family history, romantic relationships, and potential enemies. This is a built-in method of creating an immersive and entangled character backstory. Roles and Special Abilities Characters are defined by their "Role," which is a the game's class system. Players have a choice between ten different roles: Solo (combat specialist), Netrunner (hacker), and Medtech (doctor). Every role has their unique Special Ability which gives them unique gameplay mechanics. Combat and Armor Combat in Cyberpunk RED relies heavily on their body armor rather than high hit point totals. If an attack successfully penetrates a character's armor, the armor's defensive rating is permanently lowered by one point. This mechanic makes extended combat encounters dangerous and forces players to consider alternative approaches. Netrunning The game's hacking rules require Netrunners to be physically close to the computer systems they want to breach. In the setting, the global internet was destroyed, meaning remote hacking is no longer possible. Cyberware and Humanity Players can install cybernetic implants into their characters to gain new abilities or improve their stats. Every implant reduces a character's Humanity, which subsequently lowers their Empathy . If a character's Humanity reaches zero, they develop a condition called Cyberpsychosis. This generally results in the player permanently losing control of their character and no longer being able to play them.
