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!

Been a while since we posted news here, although not Nightmare House 2 related, we would like to let you know that Underhell Chapter 1 just came out!

As you know or might not know, Underhell Chapter 1 just came out, and myself and many of the NH2 team members have helped Mxthe develop and bring it to this world, and now it's finally out!

You can go and grab Underhell Chapter 1 here:

Underhell in a way is very similar to Nightmare House 2, even better, so you won't be disappointed.
You can visit the Underhell Moddb profile page for all the info you need.

Another fun fact - Nightmare House 2 and Underhell are set in the same "universe" so you can expect to hear about and meet a few characters and places you know and love.

This news post is aimed for our 2,236 watchers, don't miss it!

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.

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 :(

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.
