Cavernous chambers, strange creatures, bugs, and the remains of lost civilizations are all lying dormant under your feet, just waiting to be found. What’s waiting underneath for you?

Underneath is a solo cave exploration and mapping game of the unexpected things you encounter underground. Map, journal, and roll dice to build out a winding cave system while dealing with all the dangers and perils subterranean caverns have to offer. Build a cave system, unearth its unknown pockets, and map your discoveries.

Underneath is a solo game of map-making and journalling that you will play between the game book, your excursion journal, a map, and a pair of six-sided dice propelling your character through this cave system.

Pick your character and start rolling, the cave system has much to discover: Features, Paths, Encounters, Obstacles, Discoveries, and Caverns. Each of these different elements of the cave builds out the system and what you will find there, with each new path potentially leading you into a Scenario cavern, a large room in the cave that holds many secret and strange things.

Find yourself in Scenarios such as:

• Arora’s Cove: a fungal nightmare
• The Still: a vast quiet lake
• The Database: a series of interconnected terminals built into the rock.

Once you’ve entered the cave, it’s time to map the system, charting your exploration alongside recording your findings and responses to the prompts associated with each part of the cave into your excursion journal. Manage your gear, your skills, and the dangers in the environment while still trying to find your way back out alive.
