Ishanekon: World Shapers is the (probably) biggest free Indie TTRPG with over 2,500 character options. It has been mainly developed by Jan Luyken, aka Blaze Reason, with the aim of creating a game that can compete (if not surpass) the current biggest games on the market while remaining affordable for anyone. With its easily adaptable rules and wide range of options, from beginner-friendly to highly complex, it is designed to satisfy the needs of almost any story and play style. Description From epic fantasy and sci-fi to mundane humans facing everything from common threats to cosmic horror, Ishanekons: World Shapers’ modular design lets you easily adjust the rules to help you experience your stories. This game is designed with the idea that you bring the flavor, and the mechanics help you bring it to life. The 10 Archetypes with over 200 Sub-Archetypes, 1000+ Abilities, 600+ Talents, 300+ items and upgrades, and more allow you to build anything from a simple cat to a city-destroying kaiju. Role and complexity filters let you find what you need quickly while helping you avoid those features that might be too overwhelming for your liking. System Overview & Key Features Combat d20, Skill d10 The core of combat is built around d20 attack and defense rolls with modifiers that try to beat the enemy's Evasion and DR Power, respectively. Skills, on the other hand, are rolled with d10s, creating somewhat of a dice-based separation between combat and non-combat. Cinematic Actions While IWS has a solid tactical core that will satisfy most war gamers, it also comes with so-called “Cinematic Actions”. These allow narrative-driven actions, independent of what the rules say your character can do, balancing the rule of cool so that role players have a rules-light way to interact with the action, bringing the best of both worlds. Flexible Character Customization This system allows you to mix and match all sorts of Archetypes, features, and Abilities. It encourages such behavior and does not introduce any blocks, such as stat requirements. All sorts of interesting mechanical and flavor combinations open up once you start experimenting. This is also true for items. An extensive upgrade and crafting system exists that can turn any old blade into whatever you want. Carefully Balanced The system's core math has been calculated to ensure that every character option is viable. Breaking the game is not trivial, and you will feel strong, no matter if you are a martial, caster, or something in between. Every weapon and armor type can be wielded to great effect, and each Stat has its uses. “Optimal play” should never get in the way of what fits your character narratively. Regular Patches As a digital product, IWS can be easily expanded. Monthly patches bring new content, buff weak options, and nerf broken combos to help this game evolve and become the best it can be. New digital tools are also added and expanded, such as online character sheets and an encounter calculator. Build Your Own Creatures The website comes with more than 100 creatures, each of which has Level 0 to 15 versions, but creature templates and an online creature builder help you as the GM to create whatever monstrosities you want to throw at your players. All those 2,500 options can also be used for whatever you cook up.

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.

A local-first battlemap display tool for game masters. Cast a map with fog of war to a second "player" screen while you control everything from a private GM panel. Lodestar runs entirely in the browser with no build step and no dependencies. It runs entirely in your browser. No install, no account, nothing to download if you don't want to. You open it, load a map, click "Open player display," and drag that window over to your second screen. You control everything from your own DM panel, and your players only see what you choose to reveal. /images/general-media/1780915788_spLeMCfy.pngLodestar is completely free and open source, so you can use it, fork it, or tear it apart however you like. Maps — load high-resolution map images from local disk; pan and zoom freely. Player display — open a second window, drag it to another screen, and cast the map to your players. The player window can go fullscreen. Fog of war - Trace polygon areas and click them in reveal mode to show/hide on the player display. - Name polygon areas with a GM-only label. - Paint or erase fog with a round or square brush of adjustable size. - GM sees fog as an adjustable tint/opacity; players see solid black. Multi-floor — build multi-level locations; each floor has its own map, fog, tokens, and stairs. Navigate with the on-screen floor widget. Stairs — place GM-only staircase markers that link floors; they scale with the grid and zoom and are invisible to players. Tokens — drop, drag, label, color, and size them in grid cells; they snap to the grid and appear on both displays. Grid — toggle and adjust size, offset, color, opacity, and token snapping. Ping — Alt+click draws an animated marker on both displays. Measure — reports distance in grid cells and feet. Splash / blackout — show a splash image or a plain black screen on the player display instead of the map. Library — save full setups (image, grid, fog, tokens, floors, views) to a local IndexedDB library; export/import the whole library as JSON for backups or moving machines. When you save a map, it's stored locally in your own browser, not on a server somewhere. Nothing gets uploaded, so your maps stay on your machine. The catch is that the saved library is tied to the browser and device you saved it on, so it won't follow you to another computer or survive clearing your browser data. If you make maps you want to keep, use the Export button to save your whole library to a file. That file is your real backup, and you can import it on any device.

Wanderhome is a pastoral fantasy role-playing game about traveling animal-folk, the world they inhabit, and the way the seasons change. It is a game filled with grassy fields, mossy shrines, herds of chubby bumblebees, opossums in sundresses, salamanders with suspenders, starry night skies, and the most beautiful sunsets you can imagine. You might be a tamarin who dances with small and forgotten gods, a leporine mail carrier who relies on moths to get packages where they belong, a little lizard with a big heart and a mysterious past, or a near-endless number of other thrilling possibilities. No matter what, we’re always travelers—animal-folk who go from village to village and get to see the length and breadth of all the world of Hæth. The seasons will change as we play, and we will change with them. Description Wanderhome is built on the Belonging Outside Belonging engine by Avery Alder and Benjamin Rosenbaum. That means there’s no dice, no math, no Game Masters, and no complicated rules. It’s all about getting you into game as smoothly as possible, and filling your imagination with richly developed worlds and evocative text. The game is designed for any length of session, and with any number of folks. Whether you’re sitting down with a couple of friends for a cozy after-dinner hangout or throwing a party for a decade-long campaign, Wanderhome always has space for your experiences and needs. /images/general-media/1779960617_hvwl1UPt.webpThe World of Hæth Wanderhome is set in the wholly original fantasy world of Hæth, inspired by the works of Brian Jacques, Tove Jansson, and Hayao Miyazaki. The game hints at and builds a mythological language around forces like the bitter King of the Floating Mountain, the Lily Rebellion, the Slobbering God and the blade that killed her, and the fall of the great dragons of old, but refuses to elaborate or define them—leaving that exercise to the players through the journey itself. Instead, Wanderhome is focused on the lives of ordinary people, and the world that exists for farmers, merchants, and crafts-folk. Wanderhome is a world filled with animal-folk and their buggy livestock. Unlike many worlds with animal-folk, there is no morality or judgement ascribed to the various animals of Hæth—a snake is just as capable of being a kindly farmer as a rabbit, and you can’t assume much about someone based on what animal they are. You might find a fluffy shepherd with a herd of bumblebees, a shrewish merchant riding a stag beetle the size of a house, a lonely fox riding a grasshopper from place to place, or a praying mantis that hangs out in a gecko’s pocket.
