Rock, paper, scissors. Three simple choices, one familiar childhood game. But in Desecrated Deck, losing a round means considerably more than admitting defeat. German solo developer Elvis Posa has turned the game into the centrepiece of a first-person psychological horror experience, complete with a spectral opponent, cursed cards and an ominous ritual.
A free Windows demo is available on Steam, following the game’s participation in October’s Steam Next Fest. It is also being promoted during Steam Scream V, which runs from 26 October to 2 November 2026.
A familiar game with unfamiliar consequences
The premise places players inside a sinister basement, facing an entity across an occult ritual circle. The underlying objective remains straightforward: reach three points before your opponent. But a selection of Item Cards and supernatural Perks introduces choices that can affect health, reveal information and shift the rules between rounds.
Cards such as the Plague Doctor, Thief, Revolver and Hangman add a more sinister dimension to an otherwise accessible set of rules. It isn’t intended to be a conventional deckbuilder. Instead, the tension comes from a direct confrontation in which a familiar decision can have an unsettling result.
A story behind the ritual
Speaking directly to Coloured Static Press, Posa explained the darker folklore underpinning the experience. In the game’s backstory, villagers tell of a mysterious ritual game that could supposedly grant wishes. Desperate to save his ill daughter Lilly, a father attempted the ritual. His wish went unanswered, and tragedy followed.
For Posa, the creative challenge was pairing that mythology with something almost everyone already understands. The familiar three-way choice of rock, paper and scissors becomes the point of entry into a far less comfortable world.
The demo continues to evolve
The developer says feedback has already shaped the public demo, including a redesigned in-game manual, improved guidance and additional supernatural interactions. Steam development updates also document adjustments to camera tracking, audio options and gameplay presentation as the project approaches release.
Posa has confirmed that independent creators may record or livestream gameplay from the demo. One restriction is worth noting for video creators: licensed music used in the official trailer may generate automated claims if the trailer is reuploaded, so captured gameplay is the safer route for a feature or first look.
The full game is still in development. Although Steam currently displays 25 December 2026 as a planned release date, Posa has told us that the final release date is not yet confirmed. We would treat the store date as provisional.
