Black Mesa: Hazard Course is an add-on for the Source Engine mod Black Mesa, featuring a completely new perspective on Half-Life's Hazard Course. The Black Mesa Hazard Course will feature:

-New HD models & textures
-New dialogue & voice acting
-New maps and detailed environments
-Expanded intro, similar to Half-Life's PS2 version

Since this is a community project, we welcome people to help out in any way, from suggestions to fan-made content. Currently we are looking for people to fill these positions:


Any suggestions (within reasonable bounds, of course) are also welcome from anybody!

Media Policy

Remember that great mod, Black Mesa? Anyone familiar with the Black Mesa mod and its agonizing development cycle may remember long periods of media blackout. Since this is a community project rather than a full-fledged modding team, we are pleased to announce that, unlike the original mod, it will be our policy to strive to be as open as possible with the development process!

That's right. Expect to see half-finished areas, heavy WiPs and lots of orange and gray "dev" textures!

We do, however, announce this policy with a disclaimer: We hope that all of our followers will try their best to be as mature as possible, and realize that due to the open nature of our development process, the vast majority of media that will be released will NOT be fully representative of the final product.

This can be a good thing! It allows YOU, the followers, to give feedback early, so that we can make easy changes to give YOU what you want!

So criticize away! Just keep it civil!

Is this mod dead?

If you're reading this, then no. There is no point in letting a project die without notice. If we were to die, we'd be sure to let you know, but now that we're in Beta, development is going stronger than ever!


Black Mesa: Hazard Course requires:
-The free Source SDK Base 2007
-Black Mesa

Thank you. Have a very safe, and productive day.

Sup, guise.

*tap* *tap* Is this thing still on?

*brushes cobwebs* My, it's been a while, hasn't it? This place has grown quite dusty since the last time we posted an update. Don't worry though. *cough* We're still alive, and we're doing quite well. *hack* *wheeze*

*shuffles index cards* Anyway... today I come to you, as Benevolent Dictator For Life Hazard Course Lead Developer, to announce an important announcement, of important importance: Over the last few months at the Hazard Course Dev Team, we've been busy being dead working to reach an enormous goal.

Like what, you ask? Well, for starters, several months ago we took a look at the "Release Date" listing on the right of this page.

Go ahead, take a look. I'll wait. It's right there. ==>

I'll tell you right now: That number is really scary. When we looked at it, we shuddered to ourselves, and immediately began to panic. When the dust finally settled, we picked ourselves up and took an oath: We would try our utmost to make that number a reality.

But how?

Over the past several months, we enslaved committed ourselves to a series of aggressive milestones, each more ambitious than the last. We worked nonstop, tidying up rooms, fixing bugs, implementing gameplay mechanics, revising our script-- all in the name of one goal: Get the hell out of Alpha development stage. Achieve feature-completeness. Reach Beta.

And now, after all these months, it is with great happiness that I can finally tell you this: We did it.

The Black Mesa Hazard Course is now at the stage of development in which all planned features are implemented, and everything is in, or almost in, a near-finished state. All gameplay has been finalized. There are no more dev textures. The script is complete (thanks to JeffMOD), and will be shipped off to the Voice Acting team as soon as they give us the thumbs up and indicate that they're ready. At long last, the Hazard Course has finally entered Beta.

Behold, just a few of the many fruits of our labors:

Of course, we're not finished yet. From now on, our focus will be on polishing the mod, fleshing it out, and fixing bugs rather than experimenting with new features, thinking up new lines for the script, or rearranging rooms. There's still quite a ways to go, but I'm glad to report that we're definitely on track.

Okay, I hear the groans in the background. I get it. We all get it. Trust me, we're just as sick and tired of this long development cycle as you are. These past three years have taken a toll on all of us.

But I think the wait will be worth it. Our Hazard Course goes above and beyond what Black Mesa would have done if they'd decided to work on it themselves. Every time I fire up the latest build, I think to myself, "There's pretty much no way this kind of training level could have been a part of any game". Any sane development team would have fired anyone who attempted to pack this much stuff into "just" a game tutorial.

But we're not just any developers, and this is no longer "just" a game tutorial. We're the Hazard Course Development Team, and the mod really feels more like a whole new chapter in its own right. In a way, we were lucky that the Black Mesa team decided not to work on the Hazard Course. It gave us the opportunity to go all-out on it, instead of treating it as just one small part of an already enormous mod. I'm confident that you'll find that our Hazard Course is far more extensive than what it could have been, if the Black Mesa team hadn't decided to stop working on the Course themselves.

I'll see you guys next update. Until then, Have a very safe, and productive day.

my request may seem strange, but you can make a small part about the location as in this screenshot?
this will add diversity mod, and wow-effect, if it will added as a continuation of the original course after the time when Gordon was leaving by train

We do have outdoor areas for the intro and outtro, but they don't look at all like that April Fool's shot, and quite frankly I feel like they're a lot better too.

We are currently working toward Beta stage. The beta builds will be internal since there really isn't any point in making them public.

We are only working on the Hazard Course at this time. The Hazard Course, however, has been expanded quite a bit, so there's plenty of new stuff for you to experience.
