Hello everyone!

In case you haven't looked at the calendar, today Underhell begins!

Underhell Chapter 1



*Make sure to completely uninstall Prologue before installing Chapter One, do not install on top!*

The game ONLY requires Source Sdk Base 2007 installed, no other source games are required.
(to avoid possible bugs/crashes)

It has now nearly been two weeks since Underhell Chapter 1 has released, and where it took us nearly a month for Prologue to get 10 000 downloads, it only took us these two weeks to get them for Chapter 1.
The entire team is very happy and proud of what has been achieved, and very thankful of all the bug reports, positive and constructive feedback, and the support from the community.
You guys make us feel like we are doing the right thing!

During those two weeks, Underhell was featured on Kotaku and on PC gamer's Mod of the Week.
It was reviewed on GND-tech and had a great video review by Custom Gamer:

We are sure this is only the beginning, and hope for the best in the future!

We are also bringing you development news, it is not a secret that multiple users have had issues with the game, crashes and bugs. Most of these issues seem to be a deep engine problem, either related to graphic drivers, or corrupted cache/install.

We have managed, through our Technical Support forum thread to help dozens of users through these technical problems and to be able to enjoy the game. But truth is, Source Engine 2007 seems to have quite a lot of problems, and appears to be outdated. This is why we are currently working on porting Underhell to Source 2013! This will grant Mac support, Linux support, Occulus Rift support, as well as Multithreading, which should greatly improve performance on multi core CPUs.

We are also hard at work preparing for an eventual Greenlight release, since Underhell is currently #4 on Steam Greenlight, it is very likely that we will be greenlit in the next batch of games!
Therefore we are removing or remaking all the contributed content from the community, and slowly phasing it out. If anytime was a good time to vote for Underhell on greenlight, now is it! To ensure we will be greenlit in the next batch!

Underhell Greenlight

Strelok, our sound support has been re-creating original sounds for the game, either by recording them, or buying them from royalty-free websites that allow commercial usage.
Progsys and GuessMyName have been re-creating many props that had been contributed in the past, therefore making sure that all the items or environmental props are 100% original and made by the team.
Pedro Calvo, our texture artist is currently re-creating many materials and textures for the human clothing, and infected clothing as well as remaking any contributed blood textures we have been using in the past.
And last but not least, Alex Voysey has began to re-create all the weapon models and textures for the game, to finally call them our own.

All this are very exciting news for us and the game! We hope everyone will be able to enjoy the updated and upgraded version of Underhell before the end of the year!
We are also working on a little something else, that we will talk about in a "near" future, so stay tuned for more!

Thanks, and see you soon.

Mxthe, i have just finished Chapter One, and i have to say, ******* congratulations man, what a masterpiece of a mod this is! Did Valve hired you yet?

There are a few thing here and there about the story that i don't get right, maybe i just need to stop being a ******* pussy and try to look for those journal pages :/

Can't wait for the next Chapter! I am really curious to see how this will turn out!

I had a discussion with him over the story and it turns out that the story isn't as literal and that the course of events isn't as linear as it appears.

Oh uh...
If you've got experience and knowledge in Half Life Universe after you are finishing Underhell stuff and other you should do an Seven Hour War mod.
It will be awesome.
Thanks for reading.

Leeory, I've picked through so many mods, 1187 is probably a mod you'd want to try, but you should still try out Underhell because, frankly, it's incredible.

LeeoryHarold Sep 15 2013 replied:

I mean the action OF The Seven Hour war. Not the post-war.
1187 is post-war after war action.
I mean you are an human or an combine synth. Not an running survivor...

Also I was hacked.
Can't play it until someone does an rip-off or someshit like that.
Not joining steam anymore.

On the end of Chapter 1, i noticed that you could see the player's hand (it looked like a baloon,lol) at the left of the screen (only if you looked to the left)

I believe that is the model for the "quick grenade." I saw it too at that part. I'm sure that's not intentional, and thanks for posting this (because I forgot to).

I was wondering about that too, for a little while I was thinking it was the shoulder mounted flashlight.

If Underhell becomes a full conversion mod, would it be possible to put a price tag on it? I think it's at least worth $10.

Black Mesa : Source isn't for sale so if Jeremy wants cash he would put it max for 30 $
It's a good mod.

I wouldn't mind paying money to play this. I can think of worse games I've paid full retail price for.

If you'd like to pay money for this, why not purchase the OST to support them?

I would pay for it, and I can't say that for much.

If it's free it would still be useful to go standalone to let people without source games be able to play it. And it would be excellent to give them 100% credit for everything in there. There isn't too much to convert. Just some textures and sounds. People can help out if Valve charges a license fee.

Excellent, excellent. Always great to hear the success of indie developers, and the never ending passion that they put into their games. Have an idea what that "news" is, and can not wait for it. Take as much time that you need, more time can only bring better things. Mxthe, I salute you ser.

Great news about remaking all the assets and textures, that's quite a haul but I'm sure it will be well worth it.

If you will create new prop models, can you make they breakable? Unbreakable lab flasks, microscopes, etc and old monitors looks strange :)

I don't believe that is supported in the current Source engine they are using, but it would be a neat feature!

Swaggletooth Sep 15 2013 replied:

Of course it's supported, breakable props have been in every version of Source. The problem is just that it would just be a humungous amount of work for the prop modellers - whether or not it happens is a question of time and availability.
