The sinister deckbuilding roguelike gets a spine-chilling demo update. More days to haunt, more cards & rooms to test, and even a mysterious cat roaming the halls!?
DANGEN Entertainment and Mantis Games are excited to announce the release of the Deck of Haunts Demo v2.00 on Steam, Out Now ahead of Steam Next Fest. This major update introduces significant gameplay improvements, new content, and fan-requested features for unforgettable haunts!

Deck of Haunts is a sinister deckbuilding roguelike where players take on the role of a malevolent haunted house. In this eerie title, players build their mansion, lure unsuspecting humans into it, and terrify them into madness, or kill them, using a variety of haunting cards.
The latest demo update brings an overhaul to core mechanics and expands the content, making the haunted house deckbuilder more strategic than ever. The mansion building has been reworked, investigating humans act more realistic and will be harder to deal with, and new cards and rooms have been introduced to even the ghostly odds.

New Features and Improvements:
- Revamped Building System – The building/day phase has been redesigned to encourage building around the Heart Room and discourage clustering small rooms. Plus the highly-requested undo button has also been added!
- Dynamic Pathing – Players can now break the path to the Heart Room during the building phase, provided a valid route is made before nightfall begins when humans enter. The Entrance room can now be repositioned as well.
- Enhanced Human Encounters – Human adventurers can now arrive in staggered waves instead of all at once, adding tension and unpredictability. Some of them now possess the Pathfinder trait, allowing them to bypass the main entrance and enter your mansion through a backdoor!
- New Cards – Five powerful, new cards introduce new strategies.
- New Room Types – The ‘Mechanical Room,’ which reduces Sustain costs for adjacent rooms, and the ‘Weapon Room,’ which doubles the damage you do to humans inside of it. Additionally, The Phobia Room now drains Sanity based on the number of adjacent rooms.
- Personalized Names – Players can now enter a custom name list from which humans will draw their identities, adding a personalized touch to their demise.
- Extended Playtime – The demo now includes two additional nights, allowing players to haunt their prey for even longer.
- Polished Art & Mechanics – Numerous visual and mechanical updates for a more immersive, haunting experience.
- Azrael the Cat Joins the Fright – The mysterious feline Azrael (as seen on the internet) now roams the haunted halls, bringing an extra layer of charm to your eerie mansion!
Be sure to experience the chilling new content ahead of its full release in early 2025!
