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!

Dev Guys, can you make fix for gameinfo.txt? Cause when mod running, it loads very slow and in the SteamApps folder spawns .gcf files of EP2 Content which already has new SteamPipe file format.

What? Who EVER said anything about replacement? They are two different mods; ones a horror and the other is a thriller

The Prologue is more like an action game, not horror. Except the house.

No need to claim one mod as better than the other, especially when they take place in the same universe.

Wait a ******* minute, they do not take place in the same universe, I am calling ******** unless you provide source. *whoops* I edited this and just checked, I see now, that's pretty ******* neato actually.

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.
