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, however we have absolutely zero plans on doing so, and the mod is currently going strong.


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

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

Blog RSS Feed Report abuse Latest News: Hazard Course Direction Update Update

10 comments by JeffMOD on Apr 4th, 2015

Another day, another change of plans.

Earlier we announced our recent change of direction. We're here to announce that we will not actually be making a Five Nights at Freddy's themed Hazard Course. Despite the resounding, near deafening approval from the community at large, our lawyers have informed us that this isn't a legally viable direction, and some of our investors have withdrawn. As such, we will be sticking with classic Half-Life style!

We are, however, still looking for a Choreographer to breathe life into our NPCs - and we need that secured before we can finalize the Beta version! As we've said before, with a choreographer on our team, we should be able to release before the end of the year no problem.

And lastly, for those who are curious, that FNAHC video was actually a totally functional "prototype," made by project leader/level designer "dky.tehkingd.u," entirely within the Hammer editor over about a week and a half, with additional assets and VO by level designer JeffMOD. If you're interested, you can check it out, and play it for yourself right here.

(Update: Just pushed a missing texture fix. Download should be back up now. Thanks for your patience! -DKY)

Five Nights at Hazard Course

We hope it put a smile on you guys' faces. And if not, well... we'll just send Purple Man and give you a reason to keep it that way.

Until next update, good days, guys!

Is it worth doing all this just for 1 map?

Sigh. Okay, this time I'll just spell it out.


Give me a chance to make stupid tree puns in front of a thousand people and dammit I'm doing it.

Will this mod have new areas other than the lobby from the PS2 version?

Yep, some areas will be extended, there's some new rooms, etc. One of the images we posted is an overview, and while it's a tad outdated, it can give you a decent idea of new areas.

Firstly, I want to say that I really like and appreciate what you guys are doing! But I have just one concern though, and that is what will happen when BMS gets released on the new engine? Will you be able to adapt/convert the contents of this mod to be compatible?

Haha I replied to a similar question a while back and my teammates were like "noooo DKY why would you promise that we'd support the new Black Mesa?? too much work nooes lol" so I think I'll be more careful about my statement this time. :P

When the retail Black Mesa (and the new Free Black Mesa) are released, we will take a look at both games and make an honest assessment about whether or not it will be worth our time to support the Hazard Course in those games. Only then will we be able to better understand what we will be able to do to support it. That isn't to say that we won't try! ;)

(Personally? I have a feeling that there's a good chance that we'll be able to do it. No guarantees, but I don't THINK you should be too worried... ;) )

There's this really cool, big white box at the top of the page called the "Description." The Description contains text. This text will communicate information about this mod. So much so, that reading not even the entirety of the first sentence will answer this question.

And yes, it was worth the extra 7 seconds of time to type that out.

Yeah, but it was a really silly question that there was no reason to not know the answer to, and I had the extra few seconds.
