Heart: The City Beneath is an award-winning complete tabletop roleplaying game about delving into a nightmare undercity that will give you everything you've ever dreamed of - or kill you in the process.

It is a dungeon-crawling, story-forward tabletop RPG from the designers of Spire that focuses on what characters have to lose in pursuit of their dreams in the chaotic darkness beneath the world.

Sharing a setting with Spire, Heart expands the unreal world beneath it. It uses an expanded and updated version of the Resistance system, the mechanics that power Spire, to help you tell stories of desperation, hubris and adventure in the City Beneath.
