How to play Heart: The City Beneath
You roll a pool of d10s based on your character's strengths and the context of their actions, then take the highest die to determine the outcome. Pressure adds Stress to tracks like Blood, Mind, or Supplies. As stress accumulates, Fallout can occur, affecting you or the situation. A turn is straightforward: state your intention, understand the risk, roll the dice, manage the result, and decide your next move. Play flows between conversation, exploration, and crisis.
Players create bold, flawed characters motivated by a calling and a readiness to make difficult decisions. A professional Game Master introduces the City’s delves, factions, treasures, and horrors, establishes clear stakes, and employs safety tools. You will use character sheets, dice, quick maps, and shared notes. Online games run smoothly over video with a shared map or VTT. See common options for online play.
In a one-shot, you engage in a focused delve with a clear objective and tight pacing, aiming for memorable moments and a clean conclusion. Expect tough negotiations and a taste of Fallout before wrapping up. In a campaign, your crew builds connections and resources, attempts riskier delves, and deals with lasting scars and rewards. Obsessions deepen, relationships evolve, and the City Beneath remembers your actions. Sessions typically last 3 to 4 hours.




Frequently Asked Questions
Do I need to know about Heart or Spire to play?
No. You can arrive with no prior knowledge. A professional Game Master will explain the rules in minutes and guide you through character creation. The system uses pools of d10s and straightforward outcomes, so it comes together quickly. You will learn about Stress and Fallout as you experience them. Familiarity with Spire enhances the atmosphere, but it is not necessary. You can also choose someone who enjoys teaching beginners when you browse available Game Masters.
How is Heart different from D&D?
Heart focuses on risk, cost, and discovery rather than tactical combat. There is typically no grid. Position and narrative matter more than exact distances. You create dice pools based on your actions and location, then manage Stress to tracks like Blood, Mind, and Supplies. Fallout alters scenes and characters, not just hit points. Equipment is lightweight and tagged, magic is potent but expensive, and factions influence your decisions. Delves feel like perilous expeditions where objectives and consequences drive gameplay.
What tone and content can I expect? Is it quite scary?
Prepare for surreal horror, obsession, and bizarre wonder. Scenes may feature body horror, cults, scarcity, and psychological strain. This experience is intended for adults, not children. Prior to play, our Game Masters establish lines and veils and utilize safety tools such as Script Change or the X-card. You determine the level of intensity you desire. The game can be grim and desperate, or balanced with moments of hope and beauty. The goal is to create tense, meaningful play where you feel secure as a person, even when your character is in peril.
What group size is ideal and how long does a session last?
Heart is designed for 2 to 5 players. Fewer players mean more focus on individual characters and a more intense, perilous journey. More players introduce dialogue, strategies, and more complex consequences. Sessions usually run for 3 to 4 hours. A one-shot is ideal for a single adventure with a clear goal and a definite conclusion. In an ongoing campaign, you develop connections and resources, take on riskier explorations, and deal with lasting outcomes. Your Game Master will adjust the pacing to fit your group's style.
What types of characters can I play in Heart?
You choose a class with a unique flavour, such as Deep Apiarist, Vermissian Knight, Junk Mage, Cleaver, Heretic, or Hound. Your Calling determines what motivates you, whether it be Adventure, Enlightenment, Profit, or Protection. Abilities, equipment tags, and Beats influence your actions and development. Character creation takes approximately 20 to 30 minutes with guidance, or you can opt for pregenerated sheets for a quicker start. Expect bold, flawed individuals who are ready to trade safety for their desires.
How dangerous is Fallout? What occurs when I take Stress?
Stress accumulates on various fronts as you test your luck. When Fallout occurs, the Game Master enforces an appropriate consequence. Minor Fallout may damage equipment, change the scene, or leave a temporary scar. Major Fallout can alter your journey, affect relationships or resources, or even remove your character from play. While death is a possibility, the game often transforms you before it takes your life. Risks are clearly indicated, allowing you to decide when to push forward, regroup, or negotiate for a safer path.
Does Heart function effectively online, and what tools do you use?
Yes. Heart operates seamlessly over video with straightforward maps, shared dice rollers, and handouts. Many of our Game Masters use Roll20, Foundry, or Owlbear Rodeo, or keep it simple with theatre of the mind and a shared document. The system’s dice pools and narrative positioning are ideal for online play. If you have a preferred setup, please mention it when booking.
