Nightmare House 2 is a horror themed modification for Half Life 2 (Episode 2).

The mod started as a small map pack for Half-Life 2 in 2005. Nightmare House 2 is to continue the bizarre story of the stranger who had the misfortune to crash his car outside an old house with a horrific past.

In Nightmare House 2 you wake up inside an abandoned hospital with no understanding of how you came to be there, only a vague memory of the girl from Nightmare House haunts you. Soon it will be difficult to determine between a dream and reality. How long will it take you to realize that escape is not an option?

Nightmare House 2 is now out!

Hey guys, it's been a while...

As some of you may know, Nightmare House 2 has been broken for quite some time now.
But we come bearing good news!

Around a year ago VALVE have introduced the "steampipe" update to Steam and as a result, along with many other MODS, Nightmare House 2 broke and stopped working, I have received tons of emails, PM's and steam messages from people ever since, who just wanted to play Nightmare House 2 again.
While people came up with a few "unofficial" workarounds, the game was and still is pretty broken at this point.

I tried to wait it out, hoping the problem would fix itself with another Steam update but eventually saw this isn't going to happen, and to be honest? I kinda wanted to update Nightmare House 2 for a while anyway.

So I gathered the old NH2 team, along with a few great friends from the very amazing Underhell MOD and we all started working on a new version of Nightmare House.
We've decided to update a few other things on the way as well! you can see more about them below.

The following are features you'll find in the new and updated version of Nightmare House 2.

It actually works!

  • The new version of Nightmare House 2 is now comfortable with the new Steampipe system used by all the new games on steam. A nice "side effect" to this is that the MOD should not require having HL2/EP2 anymore, everyone should be able to play it regardless! (we're still testing some scenarios though, so don't take my word on it).

Runs on Source Engine 2013.

  • The new version of Nightmare House 2 has been ported to the last and current version of the source engine, from 2007 to 2013 to be exact. We won't get into too many details but it means lots of engine fixes, faster loading times, etc.

Map fixes and changes as well as few new bits.

  • As part of updating the MOD to the new engine I went over all of the NH2 maps and fixed many bugs I've collected over the years, added small changes to make things prettier, better and more clear, and of course added a few new bits, areas, and scares, but we won't get into details.

New models, sounds, and textures.

  • We have decided to try and get rid of as much "third party content" as possible, things like models we found online, used from other MODS (with permission of course), and took from the community. So we are hard at work creating original content to replace everything that has not been made by us or Valve.

Better visuals.

  • The new Nightmare House 2 version should not only play better, it should look better as well. Thanks to the new and updated engine we can now use better lights, shadows, and shaders for things like post-processing.

Additionally, we also have a MAYBE list, we're currently looking at these features, but we can't promise anything!

New weapons.

  • We're currently at the process of getting a new weapon modeler to join us, if all goes well Nightmare House 2 might have it's own original weapons! (instead of using models found online) Also, this time around weapons will be coded from ground up, which means they won't be a simple HL2 weapon replacement.

MAC and LINUX versions.

  • We are currently looking into compiling the code for Mac and Linux, and we hope we'll be able to bring the MOD to these 2 platforms to be able to reach a broader audience!

Oculus Rift support.

  • Source 2013 makes it easier to integrate Oculus Rift, and we are currently looking into implementing that feature. If we are able to pull it off right, Never Lose Hope hospital will look and feel better than ever in Virtual Reality.

Even more new models and textures.

  • Ultimately we want to try and get rid of HL2/EP2 assets as well, but there's lots to replace.
So yeah, there you have it.
Nightmare House 2 - 2013 promo

We don't have any actual release date yet but you can expect it to be coming soon.
We're also looking at Steam Greenlight, but we'll dig into it once the game is fully fixed first.

We hope to see you revisit Never Lose Hope hospital once again soon.

We're here for you, because we care.

Stay tuned.
The NH2 team.

Try to delete "surfaceproperties_manifest.txt" from scripts folder in the mod directory. My mod is basing on NH2 and that helped, hope it will help you too.

It worked for me, but i'm still missing quite a few textures in the game.

Edit: I got past the loading screen but the game still crashes at certain points.

I know you have sorta moved past NH2 and are onto Underhell now (which is amazing BTW, and I am not a super action fan, but the mix of action and horror is just enough) I figured I would try to post anywhere here in hopes that you Hen or another player can help me. I should start by saying I HAVE PLAYED THIS BEFORE MANY TIMES, WITHOUT ISSUES :D I am not a newbie that didn't read the description about what I need to have etc.
Here goes: I am having an issue with the pink/black checkers on the menu and in game, everywhere it is supposed to be dark. I have HL2EP2, which I purchased through Steam, AND I was playing this game fine up until recently. I played NH1 (the one included with NH2) and began NH2 and now I don't know what happened. I chekced to see if I was enrolled in the pipleline beta which I wasn't so I figured that I would try to enroll in it but even after doing that it still wouldn't work. I DID notice however, that the missing dialogue that has never been fixed no matter what I've done for HL2EP2 IS now fixed, while opening it to create a new save file, since I never had a save file on it because there weren't any voices. I am super bummed as I sorta got lost in some new games and finally came back to complete this and can't- Any suggestions would be greatly appreicated! Thanks :D

PS-I just noticed it isn't just NH2 it is also Abberation too (another HL2EP2 mod). It is definitely a HL2EP2 problem, and unfortunately I know Steam won't fix it seeing as they never bothered to fix the issue with no dialogue in HL2EP2 for the counteless people who purchased it through them. Any ideas what I can do?

Yep...I have them all...I actually talked with the dev and he had me try numerous fixes for days, and asked other friends that code to try to make a patch. Nothing has worked, and after days of trying he said there is nothing we can do for now. This happened due to the Steam update to HL2EP2 and he said that there is nothing he can do to fix it right now. Later this year he is going to try to move NH2 to another engine which will fix the problem but he doesn't have the code yet. Sorry guys, no NH2 for awhile :(

Please release a fix this instant! XD

The "surfaceproperties" issue is getting annoying :/

Trinitylynne98 Dec 16 2013, 6:17pm replied:

The surface properties issue sounds like you either don't have HL2EP2 OR you have not opened HL2EP2 and created a save file. Also seeing as this is a free mod that has 1000s of tireless hours put into it, a little less demanding may go a long way! Just saying :D

You don't really have a clue what you are talking about, do you? :P

Only way to get past this error first of all, is finding the text file in the new format "vpk" in my steamapps folder.

Then you gotta copy and paste crap to get rid of the checkered textures... blablabla.

Still the game is filled with crashes throughout.

Only thing we can hope for, is someone, or at least the developers, will at least reformat the game to the 2013 source engine.

At least that would save allot of trouble :D

That exact same error happens to people when they don't have HL2EP2 and I said that before I knew that eveyone's copy of NH2 was having issues. I was just trying to help you-and make a point about being nice to dev, didn't mean to offend you :P
So since you do know what you're talking about I was hoping that you could elaborate on what "crap" I have to copy and paste and into which folder in the steamapps/sourcemods/NH2 folder to get rid of texture error? I do not care about occasional in game crashes, just the texture issue fix would be amazing! TY :D

Awesome nightmare feeling! Better than FEAR or other horror shooter. One of the best, or the best mod in 2010.

Too much like F.E.A.R. and I wasn't too amazed by the last boss.
