HELLCARD - это a cooperative roguelike deckbuilder that plunges you into the paper dungeons of the Book of Demons universe. Whether you play solo with AI companions or team up with up to three friends, you’ll build and evolve a custom deck of cards, engage in fast-paced tactical battles and use monster placement as a key strategic element. Every decision-from card choices to unit positioning-can spell victory or doom as you face the Archdemon’s horde.

Book of Demons – a charming and inventive hack & slash that blends classic dungeon crawling with card‑based mechanics and a playful paper‑cutout aesthetic. You step into the pop‑up world of the Paperverse, where every item, spell, and skill is represented by a card. Instead of endless clicking, you build and adapt your deck on the fly, choosing the right mix of attacks, defenses, and special abilities to tackle procedurally generated dungeons beneath the Old Cathedral.
