About this game
Enter the haunting world of Nightmare House. This is the definitive edition of the highly acclaimed horror classic "Nightmare House 2".
Initially released in 2010 as a Source mod for Half-Life 2, the Nightmare House series captivated players with its intense atmosphere and gripping gameplay.
After fighting your way through an abandoned house, you wake up in the teared down, ironically named hospital ‘Never Lose Hope’. As you navigate these eerie halls, encounter terrors and enemies, team up with otherworldly allies and try to survive the unending hordes of horrors coming your way. If you manage to pull through, you might finally escape.

Free game Days Without Incident is out now!
So just last year, we released Nightmare House: The Original Mod for free on Steam. You've probably checked it out if you're reading this post here. It was our little gift to you guys for In Sound Mind's 3 year anniversary, and just in time for Halloween. Now a year later, we've just hit the button to release Days Without Incident: another small gift to the horror community that makes it all possible! We've put a lot of love and care into polishing up this oldie-but-a-goodie, so please check it out:Days Without Incident is totally free, but if you haven't already, we'd appreciate it if you threw us a wishlist for the follow-up to the Nightmare House mod: a recreated and massively expanded version of the house that started it all. Thanks so much for playing our games!Ido / We Create StuffRead full article on Community Announcements (wcs)AnnouncementsOfficial

It was never released, and was kept in a shelf for a long time. This is Days Without Incident.Read more about about the anniversary here:What's next for the mod?We're still looking into adding controller support to make it playable on handhelds- thanks NBC66!Implementing adding some localizations. We already have French, Portuguese, Spanish (LATAM), Korean and Turkish coming soon.

Overwhelmingly Positive reviews + new languages available!
Just a month ago we release Nightmare House: The Original Mod on Steam, and we've since hit 97% Overwhelmingly Positive reviews! {STEAM_CLAN_IMAGE}/45160347/cc21754b49b9637f51f110c19248f301e9da2524.png We've also just pushed support for additional languages, including: - Italian - Spanish (Spain) - Hungarian - Serbian And we have more in the works, coming soon™ : - French - Spanish (LATAM) - Portuguese And btw, we're still looking to add German and Korean. If you'd like to help, contact us via Discord if you're a translator with Source experience. Languages can be changed by launching the game while Steam is in set language, and in the properties -> language when selecting the game. To enable languages not supported by the Steam UI, such as Serbian as of writing this, use `cc_lang serbian` in the console. {STEAM_CLAN_IMAGE}/45160347/21ad1c2e66f2d0047ed827942fb742bc4ff39542.png Finally, we're working on a few fixes to the game taking in some of your feedback. Generally, at 97% positive we don't want to change much, but we'll address some balance issues and minor bugs. We're also looking into controller support and OST download. Also coming... when it's ready™ In the meantime, most of the team is hard at work cooking with a brand new zombie chef and redecorating the old house from scratch for Reimagined. We haven't published much since the Reimagined announcement but there's A LOT of content in the works, taking notes directly from the original.

Nightmare House is NOW AVAILABLE
After a few anxious delays, we’re happy to announce Nightmare House: The Original Mod is NOW AVAILABLE FOR FREE on Steam! Get it here: https://store.steampowered.com/app/2954780/Nightmare_House_The_Original_Mod/ Coming Full Circle The game is originally known as “Nightmare House 2”, a horror Source mod in 2010 released on Moddb. It packaged an earlier horror map of a haunted house, Nightmare House, with a full fledged story of a hospital run over by a failed experiment, Nightmare House 2. Nightmare House was featured in the Moddb 2010 Mod of the Year Awards, played by super early days of Markiplier, jacksepticeye, PewDiePie and others. Since 2010, we’ve only released one more iteration in 2015 in an effort to fix the issues followed by the 2013 Steampipe update. At the time, shipping mods on Steam wasn’t as accessible- so it’s really exciting for us to finally ship it here now, free and accessible to everyone. {STEAM_CLAN_IMAGE}/45160347/1912a92c7cde5ed646b7b94712af23e0b88d487f.png NH:TOM shipping went kinda like this, but hey it shipped New Old Horror Now with The Original Mod in 2024, it was super important for us to respect the same classic horror experience. But other than just making it available here, we’ve peppered it with many small improvements. To start, the mod is now under Mapbase, giving us access to new modern features such as tree sway, better lighting and fog. Thanks Mapbase! We also took this opportunity to retouch a few areas in the game, switched some textures, improved the lighting, fixed the harsh flickering lights across the maps and more. We have additionally rebalanced a few parts of the game like the boss fight, and since we’re on Steam, there are now Steam Achievements to hunt. You might want to try to find the hidden Dave Co map. If you’re looking for The Lost Files- we will add them in a future patch sometime soon, but in the meantime you can find the original sources on Moddb. {STEAM_CLAN_IMAGE}/45160347/e28a95f1aad986e254a8a8b232e9966e0...Read full article on Community Announcements (KingbladeGames)
