Delta Green TTRPG · Delta Green: The Role-Playing Game

Delta Green

Delta Green places you in the role of investigators who know too much. Modern cities, quiet suburbs, and treacherous backroads conceal impossible truths. Cases begin like a police procedural, then twist into an atmosphere of creeping dread. The mood is tense, grounded, and tragic. It is beloved for its blend of clue-hunting, human drama, and cosmic horror that does not shy away. This is an excellent choice if you enjoy thrillers and the uncanny, or wish to explore Cosmic Horror with a clear mission ahead of you.

With a professional Game Master, a session feels like a sharp investigation under pressure. You interrogate witnesses, sift through evidence, and determine how far to push. Choices carry weight. Violence is swift and costly. The tone and intensity are tailored to your group, and safety tools are standard. It is suitable for beginners who prioritise story, as well as veterans seeking grit. Ideal for 2 to 5 adults, in one-shots for tense evenings or linked operations for a slow-burn campaign.

How to play Delta Green

You roll percentile dice, which are two ten-sided dice that represent a number from 1 to 100. When attempting something risky, you aim to roll equal to or below your skill level. Describe your actions, ask questions, and follow the clues. The Game Master will only call for a roll when the outcome is uncertain. In combat, decisions are swift and ruthless. When faced with the impossible, you must test your sanity to continue.

You should come prepared with a clear character concept, a few personal Bonds, and a readiness to investigate. A professional Game Master provides the mission brief, engaging NPCs, maps, handouts, and maintains a careful pace. They adjust the mystery and horror to suit your comfort level, ranging from tense to terrifying. If you have specific preferences for tone, check GM playstyles and request an investigative, gritty, or psychological focus.

One-shots unfold a single operation within one session. Pre-generated agents are common, and the story has a distinct beginning and end. Campaigns connect multiple operations with downtime, home scenes, and significant consequences. You will observe stress and secrets accumulate over time, and minor choices may have major repercussions. The rules remain centred on investigation, consequence, and survival in both formats.

Frequently Asked Questions

Do I need to know the rules before we start playing?

No prior knowledge of the rules is required. The system is simple: you roll two ten-sided dice to generate a percentage. If your roll is below your skill level, you succeed. The Game Master will explain the rules as they arise and keep the game flowing. Your focus will be on choices, clues, and consequences, rather than calculations. If you are already familiar with Delta Green, the GM can incorporate any optional adjustments you prefer. Either way, you will be playing confidently within minutes.

How frightening is it, and how do you ensure safety?

Delta Green is intense, adult horror. Themes may include violence, gore, and psychological stress. Before play, your GM will establish lines and veils with you, and utilise safety tools such as pauses and check-ins during the game. You decide how far to turn the dial, from moody thriller to harsh horror. Consequences are significant, but player comfort is paramount. To align tone and content with your preferences, explore GM styles here: GM playstyles.

What group size and session length are most effective?

It shines with 2 to 5 players. Fewer agents create a more surgical and tense atmosphere. Larger teams allow for more skills and crossfire, but attract more attention. A typical operation lasts 3 to 4 hours. One-shots often fit into a single session. Campaign play maintains the same session length, with occasional debriefs or home scenes as time permits. Your Game Master adjusts the pacing and clue density for the group, ensuring everyone gets their moment in the spotlight.

How does Delta Green differ from D&D?

It is modern, grounded, and investigation-led. There are no classes or levels. You create an agent with skills, a job, and personal connections. Combat is quick, lethal, and typically a last resort. Supernatural elements are rare, unknowable, and perilous to utilise. Sanity and Bonds measure the personal cost of the work. In contrast to D&D’s heroic fantasy and dungeon crawls, Delta Green is more akin to crime drama combined with cosmic horror and covert operations.

Which edition and ruleset do you use?

Sessions utilise Delta Green, The Role-Playing Game from 2016. Players follow the rules in the Agent’s Handbook. The GM operates from the Handler’s Guide. Core mechanics include percentile skills, Lethality for certain firearms, and Stress and Sanity with Bonds. If you have preferences, the GM can incorporate or omit optional adjustments to suit your group. Both published scenarios and original cases are available to meet your objectives and time constraints.

Shall we create our own agents or use pre-generated ones?

Both options are viable. For a one-shot, pre-generated agents allow you to dive into the case quickly and come with built-in hooks. For extended play, creating your own agent helps you engage with Bonds and background more deeply. Group creation takes around 30 to 45 minutes, using profession templates such as law enforcement, science, military, or academia. You select stats, assign skills, and define Bonds. If you have an existing agent, the GM can adapt them to fit this ruleset.

Can we play online, and what equipment do we need?

Yes. Delta Green works exceptionally well online as evidence, maps, photos, and audio clues are easily shared. You only need a computer, a microphone, and a stable internet connection. The GM will confirm whether to use a virtual tabletop or video chat and will provide digital handouts and a dice roller. In person, two ten-sided dice will suffice. If you wish to explore online options, see online play platforms.

What players think

  • First of all, I want to say that Sebastian was really great as a DM. For his first run as a booked DM, he did a really good job. The 3 stars refer to the following: 1. We were disappointed that the adventure was labelled a One Shot and yet wasn't a complete story. Discovering that there are two more parts wasn't very positive for us, as it meant there was no satisfying conclusion to the story. 2. As new players, it was difficult for us to understand the English character sheets in such a short time. In German, it would have been much easier. Even receiving the character sheets a few days in advance would have been helpful for preparation. 3. More guidance would be beneficial. Especially for beginners, a more linear one shot would have been preferable. We wasted a large portion of the adventure time doing unnecessary things because we didn't really know how the game worked. Overall, I think the StoryForgers concept is really good and I see a lot of potential in it, especially for introducing new players to D&D. I hope you don't take my feedback the wrong way but as honest criticism. Best regards, Mario

  • Bryan was exceptional. We had a group with varying levels of experience, and he managed to keep everyone engaged and involved. His attitude was fantastic, and he made the game enjoyable for all. I particularly appreciated how he could clearly explain what was required from our less experienced players while keeping our more seasoned players on their toes with his extensive knowledge of the game. Everyone in our party had a wonderful time thanks to Bryan.

  • Dayron was fantastic. Well-prepared, punctual, and had a brilliant sense of humour.

  • Dayron was fantastic; he provided an excellent experience. Thank you!

    The Merry Meeple

  • The game was incredibly engaging. I arranged a session as a gift for my boyfriend, who is very enthusiastic about it, and he was thoroughly pleased and appreciated Leonardo's professionalism. I don't have much experience with DnD, but I found the game to be quite straightforward and enjoyable.

    Marina

  • A very good GM, Baptiste adapted well to our group and helped us progress in this one-shot. One issue was with the character sheets provided, which were not complete or clear. Some of the French translations were rather approximate. For instance, our cleric was missing spells (no healing spell) even though they were meant to have some.

    Pierre

  • Rachel was fantastic; my daughter and her friends left their game saying it was the most fun they'd ever had, and my daughter wanted to sign up for another game with her straight away. She was friendly, and her approach enabled the players to fully immerse themselves in the game by allowing them to control how they wanted their actions to be carried out. I would certainly work with her again.

    John

  • A pleasant and straightforward introduction to D&D. Amber was adept at explaining and guiding the game, allowing us as players to quickly get into the rhythm and concentrate on the narrative. Collaborating with my colleagues to devise attack strategies was an enjoyable experience and provided valuable insights into each other's characters, thought processes, and differences. Overall, I found it to be a highly enjoyable session.

  • Pim is truly brilliant as a DM! Cheerful, adaptable, and exceptionally experienced. With a group of novice players, he managed to create an amazing experience in just a few hours. He maintained control in an enjoyable manner and engaged every player in the story, regardless of whether they were vocal or reserved. If you embark on an adventure with him, it will certainly be unforgettable!
