Delta Green (2016)

Overview

Delta Green is a standalone tabletop roleplaying game of modern conspiracy and cosmic horror. Originally a supplement for Call of Cthulhu, the current standalone edition was published by Arc Dream Publishing in 2016. Players take on the roles of federal agents or contractors working for a secret, illegal organization dedicated to containing supernatural threats and covering up the existence of the Cthulhu Mythos to protect the United States. The system it directly evolved from is

Description In Delta Green, the horror is not just about monsters; it is about the toll that a life of secrecy and violence takes on the human soul. Agents juggle their high stakes investigations with their crumbling personal lives. They must navigate a world of bureaucratic red tape, government conspiracies, and sanity shattering entities while ensuring that no one, not even their own families, ever finds out the truth. The game is famous for its bleak tone and focus on the cost of the "Great Work." System Overview & Key Features
d100 Percentile System The game uses a familiar percentile dice engine. Skills are rated from 01 to 99. To succeed, you must roll equal to or under your skill rating. If the tens and ones digits match (a double) and the roll is a success, it is a critical success; if it is a failure, it is a critical failure.
Bonds and Domestic Ruin Agents have Bonds representing their relationships with loved ones or colleagues. When an agent suffers Sanity loss, they can choose to project that trauma onto a Bond to reduce the loss. This mechanically represents the agent coming home and taking their trauma out on their family, slowly destroying their personal life to stay functional in the field.
Sanity and Adaptation The game tracks three types of Sanity loss: Violence, Helplessness, and the Unnatural. If an agent experiences enough Violence or Helplessness without breaking, they can become "adapted," making them more resilient to those triggers but less capable of maintaining human empathy and Bonds.
Lethality Rating Instead of rolling many dice for heavy weapons like assault rifles or explosives, Delta Green uses a Lethality percentage. If the player rolls under this rating, the target is instantly killed. If they roll over it, the weapon deals a fixed, significant amount of damage instead.
The Home Phase Between missions (Operas), players play through a "Home" scene. They must choose how to spend their limited time: fulfilling responsibilities to maintain Bonds, seeking therapy to recover Sanity, or practicing skills. Choosing one often means neglecting the others, leading to a downward spiral of isolation.
Special Training and Agencies Character creation is deeply rooted in real world professions. Whether you are a CIA Case Officer, an FBI Special Agent, or a CDC Epidemiologist, your profession dictates your starting skills and the federal resources you can leverage during an investigation.

Delta Green: Reverberations

Roleplay focused
Conversation, character and story take up most of the table time.
Newbie friendly
New players are welcome, and nobody expects you to know the rules beforehand.
I’m looking for 2 more players for Reverberations, a Delta Green scenario set in modern-day Chicago: "A Nineties rave drug called Reverb is back on the streets, stronger than ever - and now users and dealers are disappearing." Game details System: Delta Green Scenario: Reverberations Date: Saturday, 8 August 2026 Time: 13:00 EEST / 12:00 CEST / 11:00 BST Format: Online (Discord) Length: The scenario may take 1-2 sessions. If necessary, an additional session will be held at the same time on Sunday. What to expect My games tend to be discussion-heavy. Players spend time comparing theories, examining evidence, deciding what different clues might mean, and discussing what they want to investigate next. I use lots of images, clues, handouts, and in-world documents to make the investigation feel tangible. I try to reward curiosity and creativity: noticing details, following leads, asking questions, and making use of the locations and NPCs. My goal is to make the game as immersive as possible. This is an investigative horror game rather than a combat-focused one, although combat is always an option. The point is not necessarily to discover the "correct" answer, but you should enjoy engaging with the mystery and making decisions as a group. I strongly prefer players who have not previously played or read Reverberations, so that everyone can experience the investigation and its surprises naturally. That said, new and experienced players alike are very welcome, and you do not need to know the Delta Green system at all before playing. Platform and registration This will be an online voice game. Accepted players will receive the voice-chat information, character materials, and other game documents before the session. You can read the event details and request a place through my Delta Green calendar: https://luma.com/deltagreen

Hello, fellow gamers. My name is Marlon, but everyone calls me Jay-long story there that I won’t get into. Anyways, I’m the forever DM in my family, and I run weekly podcast games for my wife. We’ve designed a tabletop RPG called Prosperon: A Bio‑Cyberpunk RPG, and we’re actively looking for more playtesters. If that interests you, shoot me a message and we’ll make it happen. With that being said, I’m also an active player in several games. I’m currently in a Blades in the Dark campaign every Thursday, which is absolutely amazing, and I have a few open biweekly days where I can commit to another game-as long as it’s the right game, the right crew, and the right day and time. That’s all for now. Take care, and don’t forget-have fun at your table.

Character sheets
A free, accessible, browser-based character creator and editable sheet for Mongoose Traveller 2022 — every roll cited, every choice logged, every character saved locally. Description Traveller Lifepath is a free, browser-based character creator and editable sheet for Mongoose Traveller 2022. It walks players through the full Mongoose 2022 lifepath — basics and species, characteristics, background skills, pre-career education (University, Army Academy, Marine Academy, Navy Academy), career terms with their full survival / event / commission / advancement loop, mustering-out, the post-creation skill package, and a final reviewable character sheet — without ever leaving a single browser tab.                                                              The tool offers three ways to set characteristics. Players who want the classic experience can have the site roll 2D × 6 into a pool and assign each value to whichever stat they like. Players who prefer their own physical dice can enter results manually; the site still tracks every DM, target, success/failure, and aging effect. Players who'd rather skip randomness entirely can use the included point-buy method (42-point budget, 2..12 per stat). PSI is rolled separately when psionics are enabled, and the Psion career unlocks accordingly.  /images/general-media/1778159165_rhvJ8xSn.png The character-creation rules are implemented as a typed effects engine — TypeScript discriminated unions with exhaustive switching — so every rule lives in one place and can be tested in isolation. The project ships with around 360 automated tests covering qualification, commission, advancement, aging crises, mishaps, life events, connections, the skill cap of 3 × (INT + EDU), pre-career education, and the Mongoose 2022 errata clarifications for Vargr and the Vacc Suit skill. A full audit trail of every rolled die, every applied DM, and every player choice is captured to a roll log that updates in real time. The post-creation sheet is a fully editable Mongoose-style character record. Skills, careers, equipment, weapons, armour, augments, connections, benefits, and free-form notes can all be edited inline; values save automatically to localStorage with cross-tab synchronisation, and the sheet is print-friendly (one panel per printed page, ink-friendly styling). Every character in the local library can be exported and re-imported as JSON for backup or for handing off between players.                                                      Two visual themes are included: a light "Little Black Books" look in the spirit of Classic Traveller, and a dark "Imperial" theme — plus a System mode that follows the operating system's light/dark preference and reacts live when it changes. Theme choice is remembered between sessions.                                                                    Accessibility is treated as a first-class concern. The interface meets WCAG 2.1 AA contrast requirements in both themes (verified by an axe-core audit suite that runs as part of the project's tooling), every interactive element has a visible keyboard focus indicator, icon-only buttons carry ARIA labels, and the layout includes a skip-to-content link for screen-reader users.            /images/general-media/1778159170_sbkOfhno.png Other features include undo across the wizard (rewinds to the relevant picker after popping a character snapshot), URL-based debug logging (?debug=1), the Connections rule for shared PC backgrounds, an aging-crisis path with medical-debt accumulation, and an honest "unofficial fan tool" disclaimer in every place it matters.                            The project is open-source under the MIT License, runs entirely client-side with no backend and no account requirement, and uses privacy-friendly analytics (no cookies). Bug reports, rules questions, and pull requests are welcome on GitHub. Links bytesbynelson.github.io - Live tool github.com - Source code github.com - Issue tracker / feedback

Dungeondraft

Dungeondraft

English
Paid
Universal
Dungeondraft is a specialized, standalone map-making software designed specifically for creating high-quality TTRPG battlemaps. Developed by Megasploot (the creator of the world-building tool Wonderdraft), it was released in 2020 and has since become the industry favorite for GMs who want to build detailed, tactical maps without needing professional graphic design skills. It is famous for its "smart" tools that handle walls, lighting, and object scattering automatically, allowing a full encounter map to be completed in minutes. Description Dungeondraft bridges the gap between simple grid-sketching and complex image editors like Photoshop. It features a unique, hand-drawn aesthetic that fits perfectly with modern fantasy games. The software is built for efficiency; drawing a room automatically places floors and walls, and the integrated lighting engine allows you to place torches that cast realistic shadows in real-time. In 2026, it remains a "buy-once-own-forever" staple, free from the subscription models that have taken over much of the creative software market. System Overview & Key Features Smart Wall and Floor Tools Building a structure is as simple as clicking and dragging. The tool automatically handles corners, joins, and textures. If you move a wall, the floor expands with it, and placing a window or door automatically "cuts" the wall to fit the asset. Integrated Dynamic Lighting Dungeondraft allows you to place light sources with customizable colors, intensity, and flicker. These lights interact with the walls you've drawn, casting shadows that provide an instant sense of depth and atmosphere to any dungeon or tavern. Universal VTT Export One of its most powerful features is the ability to export maps directly into formats for Foundry VTT, Roll20, and Fantasy Grounds. These exports include the "wall data" and "light data," meaning you don't have to redraw your walls in your virtual tabletop software. Object Scattering and Paths The Scatter Tool allows you to "paint" clutter like rocks, grass, or debris with randomized rotation and scale, making environments feel organic. The Path Tool lets you draw roads, rivers, or fences that follow a smooth curve automatically. Massive Custom Asset Support While the base software comes with a complete art style, the community has created thousands of additional packs. You can easily import assets from famous artists like Forgotten Adventures or Crosshead, allowing you to completely change the look of your maps. Terrain and Water Painting The software includes a multi-layered terrain brush that lets you blend different textures like sand, dirt, and grass. The water tool allows you to create pools and rivers with adjustable transparency and "edge foam" for a professional finish.
