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.

Hi All, long-time TTRPG player and GM. Started with BECMI D&D, then AD&D 2e before moving onto Rifts, Shadowrun, and original World of Darkness. Getting back into the swing of things, and trying out the online space. Would really like to try ShadowDark and some of the newer OSR games. Sorry not sorry that I'm not a fan of 5e, new World of Darkness, or Critical Role type games (Daggerheart, Candela Obscura). You can try to change my mind, but keep your fingers crossed.

Tabletop Roleplaying Games

Call of Cthulhu (2014)

TTRPG
Beginner-friendly
English
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.

Dungeons & Dragons 5e (2014)

TTRPG
Beginner-friendly
High-Fantasy
Dungeons & Dragons 5th Edition (D&D 5E) is a heroic fantasy tabletop roleplaying game published by Wizards of the Coast. Released in 2014, it is the edition that brought D&D from a niche hobby into mainstream pop culture - showing up in TV shows, podcasts, and actual-play streams, and introducing millions of new players to the hobby for the first time. 5E was designed after a massive public playtest ("D&D Next") with the explicit goal of being approachable to newcomers while still satisfying veteran players. The Basic Rules are free, and a game can start with nothing more than those rules, some friends, and a set of dice (or a digital dice roller app). In 2024 the core rules received a significant revision, now commonly referred to as Dungeons & Dragons 5.5E (2024). Both versions are fully compatible and most groups mix material freely. The system it directly evolved from is Dungeons & Dragons 4E (2008) Description In D&D 5E, players create fantasy adventurers (a half-orc barbarian, an elven wizard, a tiefling rogue) and one player takes on the role of the Dungeon Master (DM). The DM builds and describes the world, voices the non-player characters (NPCs), controls the monsters, and acts as both the lead storyteller and the rules referee. There is no board. The game is a conversation: the DM describes a scene, the players say what their characters do, and the dice decide what happens when the outcome is uncertain. A typical session runs three to four hours with a group of three to six players plus the DM. The game describes itself as resting on "Three Pillars": Combat, Exploration, and Social Interaction. A single session might include all three, from tracking a monster through the wilderness and negotiating with a shady merchant to fighting a troll at the entrance to a cave. Combat is the most mechanically detailed of the three and tends to take up the largest share of table time, though groups are free to lean as hard into roleplaying or exploration as they like. The default assumption is a high-fantasy world filled with magic, monsters, and ancient ruins. The flagship published setting is the Forgotten Realms, but Wizards of the Coast has released adventures across a range of worlds, and many DMs create their own. The game does not ship a single canon story. Every table's story is different, shaped by what the players do. 5E is designed to be approachable. The core philosophy is "rulings over rules," meaning that when something comes up that the rules do not explicitly cover, the DM is encouraged to make a quick call and keep the game moving rather than stopping to look things up. The rules reward creativity and improvisation, and the system explicitly expects that no one at the table has memorized the entire rulebook. That said, the DM carries most of the preparation work between sessions: building encounters, preparing maps, and keeping the story moving. Players can show up with nothing but their character sheet and a set of dice.

Untitled Game is a Dungeons & Dragons actual play podcast and the premise is pretty simple: A group of strangers crash lands on a remote tropical island and survival instinct quickly kicks in. The deeper they go into the jungle, the stranger things get—old cave paintings, impossible storms, things whisper threats in the dark. It’s played pretty loose and natural—no actors, no heavy editing polish—just a group of nerds leaning into the creepy weirdness and seeing where the story goes. Sometimes tense, sometimes funny, occasionally very bad decisions, always a bunch of cursing. If you’re into: slow-burn mystery horror with a weird edge tabletop actual play that feels more like a late-night campfire story …you might just enjoy it. Join our survivors as they peel back the layers of a mystery where every choice matters - and one wrong step might just be their last.
