Killing Stone is a deckbuilder folk horror about a family cursed by the devil

The Killing Stone: A Cursed Family Locked In By the Devil’s Card Game

When you make a deal with the Devil and lose the bet, they will come knocking to collect. The Killing Stone takes that classic soul bargain and transforms it into a Yu-Gi-Oh card battle. You must play the game, battle with enchanted cards and miniatures, and break a family curse.

Dealing Out the Family’s Debt Cards

You arrive at the Svangård estate as the Maven — the masked apprentice and friend of the late Mariken Svangård. She was a master of the dark arts, brilliant and reckless. Mariken spent her life bargaining with demons for power. Now she’s dead. Her debts didn’t vanish with her passing. Instead, they have sunk their claws into her family, twisting each member in ways they don’t fully understand. Your job is to cleanse their souls before the Devil comes to collect.

The story unfolds in first‑person as you explore the manor, interview the Svangård relatives, and piece together the truth behind Mariken’s final days. The writing slips between period‑accurate 17th‑century English and modern clarity, giving the whole experience a dreamlike, fractured quality. Every conversation reveals a secret, a sin, and another reason the Devil is circling overhead.

Ritual Combat on the Fanghella in The Killing Stone

Each family member has a card deck shaped by their personal history and inherited sins. Throughout the Killing Stone, corruption will surface in a family member, forcing you, the Maven, to cleanse them through ritualistic card combat. The cleansing ritual commences on the Fanghella, a.k.a. the ceremonial Killing Stone resting in the centre of the board. When this situation unfolds, the board comes to life with animated figurines that twitch to life, and spell effects that crackle with occult energy.

The Reserve System lets you hold cards above the battlefield and watch the figurines battle out your choices. Demons will tempt you with bargains between encounters, offering power at a price that always feels a bit too steep. In doing so, you can either cleanse these cards or induce the corruption.

Every run will eventually throw down the gauntlet and lead toward a showdown with the Devil himself. The demon loves games and will put you through various challenges with every encounter. If you win, you save a soul, but if you lose, the Devil adds another name to his ledger… permanently.

Cultic Atmosphere and Design

The Killing Stone’s SvangÃ¥rd estate is cold, dim, and oppressive, lit by candles that barely push back the Arctic darkness. The art style screams Chiaroscuro, complementing the icy folk-horror aesthetic. The overall environment setting has painterly textures and stark lighting to bring out the gothic features of the manor. Overall, the look and feel of the SvangÃ¥rd estate is like a haunted painting come to life.

On the board, the animations are deliberately uncanny. The board figurines‘ movements are stiff and have a puppet‑like precision as they reenact ancient rituals. Spell effects burst with ritualistic flair, making each battle feel like a ceremony rather than a skirmish. On the other hand, the occult energy flows like silk, making it appear more otherworldly against the rigid world around it.

The demon designs are melded with historical familiarity and otherworldly aspects. The unholy creatures outside the board stand out for their twisted human disguise. The card game’s minatures all carry unique features that seem to centre around their purpose and abilities. All monsters have unforgettable aspects that make them easy to differentiate and wary of what they can do.

Voices That Whisper, Watch, and Wait

The soundscape of the Killing Stone breathes the uncanny life into the dreary atmosphere. The soundtrack blends droning ritual tones with eerie folk instruments, creating a constant undercurrent of tension. Voices are heard echoing through the dark halls of the manor, and demons add to that concophony with layered, distorted tones.

Along with the supernatural sound effects, the environmental sounds (creaking, wood, distant winds, muffled voices) make the estate feel alive and restless. The devs definitely put a lot of effort into the mood, voice work, and presentation because this game has immersion for days!
