Nightmare House 2 is a horror themed modification for the Source Engine.

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!

Hello again and happy Halloween!

Today, just in time for Halloween, we’re proud to release an updated version of Nightmare House 2!

More than 5 years ago we released Nightmare House 2, which proved to be an immediate success. The mod was and still is very popular, however it was later broken by a Steam update. We tried to wait it out, but it soon became clear that NH2 would need to be updated as well.

Almost a year has passed since we resumed work. On the way some new members joined the team, and it became much more than just a quick fix, it became a full update, with us fixing many bugs and adding several new features.

And you can download it right now!

Nightmare House 2 (2015)



The mod now runs on Source 2013:

NH2 was originally created on Source 2007, the new version has lots of fixes, faster loading times, and other small tweaks. Most importantly compatible with the Steam update.

No Source games are required to run NH2:

That's right, you no longer need to own Half Life 2, Half Life 2 Episode 2, or any other Source engine game. NH2 requires only a registered Steam account.

Note: If you do not have any Source engine games installed, Steam will automatically download the base assets (several gigabytes in size) when NH2 will be launched for the first time.

Mac OSX and Linux support:

The release you’re about to download will run on Windows, Mac OSX and Linux. One download, three operating systems!

New weapons:

NH2 originally had simple Half Life 2 weapon replacement models we found on third party websites. In the new version the weapons have been modeled, animated, and programmed by ourselves, and now look and behave differently than the original NH2 weapons.

New models, textures, and sounds:

We managed to get rid of all the third party assets we used in the original version. All models, sounds, and textures found in the mod were created by Valve or us, with the exception of some world textures from

Map changes and bug fixing:

We’ve added new things to all of the NH2 maps, tons of bug fixing, re-balance, and even some new things here and there we’ll leave you to find.

It’s also worth mentioning all maps got a full re-texture overall, you shouldn’t find any Half Life 2 textures now. (Special thanks to

Better visuals:

Using Source Engine 2013 allowed us to now have better lighting, screen effects, and sharper dynamic shadows.


This modification requires a registered Steam client.

  1. Extract the NH folder inside NH2.rar to: Steam\steamapps\sourcemods (if sourcemods doesn't exists create it).
  2. Restart Steam and Nightmare House 2 should appear in your game library.

Note that you are not required to own any Source engine based game (Half-Life 2, etc) in order for NH2 to run.

However, steam will automatically download the base assets when trying to launch NH2 without any Source based game installed, so get ready to download a few extra gigabytes.

If you do not know where your main steam folder is it can usually be found in C:\Program Files on Windows, and in your home directory on Mac OSX and Linux.

YOU MAY CRASH AFTER THE INTRO, to fix this do the following:

  1. Go to your Steam library, click on games, from the drop menu select tools.
  2. In the tool list find "Source SDK base 2013 singleplayer", right click on it, select properties.
  3. Go to the BETAS tab, you should see a little down arrow under the "Select the beta you would like to opt into" title, click on it and from the dropdown menu choose "upcoming-" and click close.
  4. Steam will download some missing files, when done, restart your steam and launch NH2 again.


Steam Greenlight:

Many people asked us to set a Greenlight page for NH2, we want to, but first we have to see if it’s still relevant, NH2 was released in 2010, and was a huge hit back then. However Greenlight didn’t yet exist, so we may have missed the boat.

However, if we see NH2 is still being played by lots of people, and is worth it, we will look into setting up a Steam Greenlight for NH2.

How can you help us:

Spread the word! Most of the people who will see this news article are people who have already played NH2 before. However there are many people out there hungry for horror games who simply don’t know about NH2. Tell people! Make let’s plays (We enjoy watching them)! Now that NH2 doesn't require any Source based games it is more accessible than ever, let people know!

There you have it, see you in another 5 years!

Very excited for the updated version and the new goodies added in. SO- my issue is this: I have NH2 on Steam already and actually spent months begging all my Steam acquaintances to help me get it to work. Believe it or not we did get it to work with the help of a few awesome people including Hen7. Anyway, my question is when I go to extract the NH2.rar file into the Steam/steamapps/sourcemods folder, I already have a NH2 folder there from the other copy. Do I still extract this one to there, or do I need to make another one or delete the pone I have etc. Please let me know if anyone has any advice. Thank you so much!

Delete the old version entirely, as it is not relevant to anything anymore.

You can either delete the old version, or edit it's folder and gameinfo.txt file to have names.

Nice secret level you added there. It was random as hell. I wonder if anyone else found it because nobody commented about it yet. What does the map's name mean anyway?

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.
