The Expanse RPG

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.

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.

Released in 2014 by Chaosium, Call of Cthulhu 7th Edition is the latest version of the cult-classic cosmic eldritch horror role-playing system originally launched in 1981. The story is based off of the  literary works of H.P. Lovecraft and lovecraftian works. Instead of setting the players up as heroes, the characters are regular investigators who are exploring cults, forbidden knowledge and various eldritch-cosmic entitites and threats. Description Occupations in the game for the characters include academics, reporters, and private investigators. The gameplay loop revolves around uncovering information, analyzing clues, and evading dangers. As the supernatural elements in the game are considered more powerful than the investigators, they have are not expected to actually confront most of the threats head on. Instead they usually have to resort to avoiding or escaping any situation that may arise. Combat is lethal and usually leads to characters getting permanently killed or pushed to insanity (which eventually is the same).  System Overview & Key Features Percentile Framework (d100) Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Pushed Rolls If a character fails a skill check, they may attempt to "push" the roll, allowing for a second attempt. This requires the player to come up with a new, more desperate approach to performing the task. If this subsequent pushed roll also fails, the Keeper describes a severe and immediate negative consequence. Sanity and Madness A core mechanic of the system is the tracking of mental stability. Investigators lose points from their Sanity gauge when exposed to anomalous creatures or disturbing truths. Drops in Sanity result in the character experiencing temporary or permanent forms of madness, which can manifest as new phobias, delusions, or a temporary loss of player agency over the character. Bonus and Penalty Dice To account for situational advantages or disadvantages, the game employs a system of bonus and penalty dice. If a character possesses a distinct advantage when performing a task, an extra d10 is rolled and taking the higher result. A disadvantage means rolling an extra d10 and taking the lower result. Combat Lethality Physical altercations are inherently dangerous by design. Investigators possess limited hit points, and the damage output of both conventional firearms and anomalous entities is high. Recovery mechanics are slow, simulating realistic healing times. This structural lethality serves to discourage combat and incentivize stealth and investigation. Expendable Luck Players can spend points from their character's Luck pool to retroactively lower a dice roll. The points are subtracted on a one-to-one basis until the dice result qualifies as a success. This ensures that the Luck pool is a limited resource which should be used and utilized in the most critical situations.
