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!

I found a fix for NH2 in a thread on Steam. Haven't tested it but you might give it a try.

Hey guys, sorry the game is broken right now, it was a steam update that broke everything, someone on our forum posted a "dirty workaround" to get the game to work, but it will require you some work, for all that is interested:

Additonally download this fix I made by myself:

Start the game with Nightmare House 2.bat
You must always close hl2.exe with TAB manager after leaving the game or you can't start any Source game afterwards (not even NH2 itself).
Other than that, the game should run just perfectly fine (even with Steam overlay!)

It seems you also have to take the sound folder from HL2 (is included) and place it into NH2 (don't overwrite any files!) to have all sounds working. THEN it should work as supposed to be.

I actually talked with the dev and he had me try numerous fixes for days, and has even 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 Source 2013 engine which will fix the problem but he doesn't have the code yet. Sorry guys, no NH2 for awhile :(

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.
