Submundus

When fate deals you a bad hand, you must play it right.
You wake in a cell deep beneath the world, with no memory of who you are or why you were thrown away. Beyond the bars: caves, ruins, and the peoples of the deep — and somewhere far above, the light. Submundus is a survival roguelike deckbuilder where your deck is not just your weapon. It is your body, your pack, and the passage of time itself.

YOUR DECK IS YOUR LIFE
Every wound you take, every meal you skip, every hour without rest enters your deck as a card. Survival damage doesn't just hurt — it clogs your hands, dilutes your strategy, and slows you down. Manage it, purge it, or be buried by it.

YOUR DECK IS YOUR CLOCK
Time in Submundus passes in deck cycles. A lean deck moves fast; a bloated one drags. Hunger, thirst and fatigue accumulate as time flows — every card you add is a choice about who you are and how fast you live.

EVERYTHING IS A CARD
Weapons grant cards. Spells inject cards. Enemy poison and disease infest your deck as cards. Even your memories return as cards — fragments of a past that someone wanted buried. Even light matters: your torch burns down in cycles, and the dark below is not kind.
NO TWO DESCENTS ARE THE SAME
Every run carves a new underground. Rooms, encounters, factions and fortunes are procedurally generated — then persist for the length of your run. Backtrack, map the depths, and choose your route through a world that remembers your passage, even if no one remembers you.
MAKE ALLIES. MAKE ENEMIES. OR TRUST NO ONE.
The deep has its own peoples, its own wars, and its own grudges. Take sides, or walk alone — discover who you are, why you were forgotten underground, and fight your way back to the surface. If the surface is still waiting for you.
FOUR WAYS TO SURVIVE
Begin as a Brute, a Contrabandist, an Elven Apprentice or a Dwarf Acolyte — starting points, not cages. Each remembers different fragments of the same buried truth. Build your character freely: any path is open to anyone strong enough to walk it.
