Hell Deck

Hell Deck is a roguelike deckbuilder defense game set in the depths of Hell. Holy angels descend to purge the abyss, and you must lead its demons against them by changing the laws of nature and building a food chain that can repel the invasion.

The abyss under attack

Angels are the predators hunting you, while the demons under your command fight to survive. The battlefield is a volatile ecosystem where survival depends on predation and sacrifice, and power comes at the cost of flesh.

Build an ecosystem

Your units hunt one another rather than simply holding formation. Place them on a strictly limited tile grid, where each placement can set off an uncontrollable chain reaction. Cannibalism consolidates power, while accidental placements and deliberate sacrifices can trigger biological mutations that turn weak grunts into apex predators.

Manage your hand and inventory bag as you arrange units and their interactions. The right biological synergies can help you overwhelm hundreds of incoming enemies at once.

Death and upgrades

Death is part of the experiment. A mysterious, omniscient voice watches your failures and promises to “fix you” each time you break. When you return to the lobby, you unlock permanent upgrades.
