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at large, our lawyers have informed us that this isn't a legally viable direction, and some of our investors have withdrawn.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!

This will probably reach the final release, and all source devs know that Valve did some important changes - SteamPipe and stuff like that.

The chapter is 15 minutes long. It's practically a demo in itself.

And it's not gonna die. Slow =/= dead.

While we appreciate the excitement, we're sure you'd much more enjoy a finished and polished product than a "demo" of the mod in its current alpha state.

Valve fixed the issue with Source SDK almost a couple of weeks ago.

We haven't updated with a new post, but some of us have been able to resume development. IIRC, there are still one or two down for the count, and we're all busy with exams and work, but things are getting done.
We'll probably update the news once we get some media to show.
