You wake up in the depths of Hell, but it isn’t the demons you should fear. Holy angels are descending from the heavens to purge the abyss, and you are their prey. To survive, you must take command of Hell’s denizens and rewrite the laws of nature.

Hell Deck is a dark, twisted roguelike deckbuilder defense game. Here, the battlefield is a living, breathing, and volatile ecosystem where survival is bought with flesh. Force your units into a brutal cycle of predation and sacrifice, engineer a grotesque food chain, and repel the holy onslaught.

"WHY DO YOU DOUBT THIS PARADISE?"

Forget everything you know about good and evil. In this world, angels are the apex predators hunting you down. Lead the demons of the abyss, adapt to the harsh reality of the underworld, and turn the holy invasion into a crimson feast.

Your units don’t just stand in formation—they hunt each other. Master a unique "Ecosystem Deckbuilding" mechanic where power is consolidated through cannibalism. Accidental placements and deliberate sacrifices trigger grotesque biological mutations, turning weak grunts into god-like apex predators.

Space is your most precious resource. On a strictly limited tile grid, every single placement can trigger an uncontrollable chain reaction. Manage your hand, monitor your inventory bag, and orchestrate the perfect biological synergy to decimate hundreds of oncoming enemies at once.

Death is merely part of the experiment. As a mysterious, omniscient voice watches over your failures—promising to "fix you" each time you break—you will unlock permanent upgrades upon returning to the lobby.
