Enter the House: Heartworm’s Haunting Tale Gets a Release Date
Indie developer Vincent Adinolfi and horror maestros at DreadXP are excited to announce the release date of their highly anticipated lo-fi survival horror. Heartworm, a standout indie title highlighted by media in ‘Best of PAX’ and Steam Next Fest roundups, is launching on Steam on July 31, 2025. Fans of the classics from the psychological horror golden era of the 90s have been waiting for the game, and Adinolfi has crafted a thrilling love letter to those who appreciate the unease of haunted locations.
Step into a world where memories and mourning blur the lines between reality and supernatural visions. In this atmospheric survival horror game, you’ll follow Sam, a young woman overcome with grief after the passing of her beloved grandfather. Her quest for closure leads her into a deep rabbit hole of online forums, and ultimately to a remote haunted house up in the mountains. What begins as a desperate attempt to reconnect with the past quickly spirals into something more sinister and inexplicable, as she pushes deeper into the unknown armed with only a camera and her determination to venture further.
Blending the spirit of the survival horror classics like Resident Evil and Silent Hill with modern gameplay options, Heartworm tells a deeply personal story through pre-rendered and in-game cutscenes, classic and mind-bending puzzle-solving, and limited but meaningful tense combat using a camera as your weapon to fend off what lies ahead. Featuring optional tank controls, PSX-style visuals, and retro effects, you can tailor the experience to make it feel like it’s straight out of the late 90s, or scale back the nostalgia a little bit for a more modern experience. An original soundtrack and evocative environments guide you through 4-6 hours of exploration, tension, and discovery, with multiple endings waiting on the other side.
Enter the house. Face the other side. Uncover the truth that these mountains hide.

Heartworm launches on Steam on July 31st, and the free, highly acclaimed demo is available now. The game will be available in English, French, German, Latin American Spanish, Japanese, and Brazilian Portuguese.
