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.

O.M.G. This has got to be about the scariest game I've ever played, I mean it, there were bits where I'm thinking "I really don't want to go down this corridor/open this door!" Incredible graphics . Some very nice gameplay concepts. Sat up half the night playing and only took a break about halfway into the endgame sequence.

Also, you never forget this is a HL game, so there's still a good dose of vent-crawling, puzzle-solving, and jumping. Simply one of the best.


My only real criticism was the endgame. I took a break then partly because it was 3 AM but I was also feeling that it was getting a bit tedious. As it happened that was just before things started getting weird again, and that helped redeem it. Those little zombies, which were absolutely terrifying the first time we see them, and in the warehouse, got to be little more than an annoyance in the Core sequence, and they are so dim all you need to do is stand behind a piece of fence, shoot them, then run up and do your work. I'm not a designer, so I'm not sure what i might have done differently, but that bit did seem to drag. Clever bit with the supply boxes, though! And the actual artwork and design of the Core was great too.

Speaking of the warehouse: slight glitch. Got to the end with 2 SWATs, and one says you have to wait for everyone. Well, one of them just kind of disappeared -- still showed all 3 on the HUD of course -- went all the way back through, but I had to run that whole sequence again. Kept us all together that time, and no problem.

Favorite bits: 1) those black shadows in the corridor! I kept waiting for them to do something! I was practically whimpering on the return trip. 2) The mannequins in general, and esp. where the SWAT is waving at you through the window, and when you go through the door it's the mannequin. Talk about your blood running cold! Excellent, excellent game. Bravo.

the description for the download states:

IMPORTANT: This modification requires a registered Steam client with Half Life 2: Episode Two installed.

quite clearly

I don't see thay anywhere in the description...I looked everywhere, and just checked again..where? I even clicked the release news posting, where it ususally will say the requirements and it isn't there either. It IS complicated for people because it isn't listed right there and it is posted under the wrong episode of HL, as it is listed as a HL2 mod, when it is really a HL2EP2 mod. That very well may not be the devs fault, I don't know, but it is not "quite clear" that much I do know-Just saying ;)

I am not trying to look the gift horse in the mouth here, on this awesome, and free mod. In fact I always support the devs on here and never complain. BUT-these HL2, HL2EP1 and HL2EP2 mods aren't all seperated into categories based on the episode you need to run it, (which some are, and that makes it only more confusing). The devs should post a description of EVERYTHING you need to make the mod run, including ALL of the Source SDK files needed. This mod is listed as a HL2 mod but you really need EP2 to run it. I got HL2, just to ply this mod after hearing and see nothing but amazing stuff! Once I downloaded, and opened it lead me to Steam to download 1 Source SDK 2007 file, then I tried to play the mod,it gave me an error (the exact error is listed on this page of comments from another user) saying I was missing something outta the EP2 file. Then I get EP2, and it still errors. Then I read through 15 pages of comments, and see someone saying we need SSDK 2006 and SSDK also. Don't get me wrong there are plenty of idiots who don't read the description and just blindly download and then wanna know whats wrong. But-I have looked and can't find the info. Could I google it, and sift through all the comments, and ask questions and eventually figure it out? Sure! But-WHY? BTW-I now have ALL the SSDK files, AND both HL and HLEP2 and it STILL is giving me same error. I am gonna get HL2EP1, but am not hopeful at this point- Could someone be so kind as to post what is needed to run this mod? TY

I feel SO bad posting this after reading back from page 138-77 or so. The devs got b!tched at so much for stupid things, I will not take a mod's category for granted and take the time to read the older comment sections. Perhaps Desura should have categorized this under HL2EP2 and saved both the devs and players a lot of grief! I cannot believe the amount of time that went into making this mod, and how rude people were while waiting for it. Still haven't gotten this mod to work, but I (think) know why I have the error now, after lots of reading...Even though I had to figure it out on my own, If I could pull my own comment down I would in an instant!! So sorry.

Same error here-I think we need EP 2 to play this..Not sure, I am waiting for a response too! It took forever to download that Source SDK 2007 file from Steam, and now I still can't play! :(

I just got HL2-EP2 and it still won't work. I will try to contact Steam, but I have a feeling they will blame the mod! I tried downloading the mod "Grey" for HLEP2 and that seems to work. I don't know what the problem is. I heard nothing but amazing things about this mod. Finally got the correct HL episodes to play it (I only had HL1 before) and still can't-anyone have a suggestion?

I got hl2 ep2 today and it worked for me. I think you may need both half life 2 and hl2 ep2 to play it. And I think a few other mods need both games as well. It's should be more specific on exactly what games are required.

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.
