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. 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.

Beta Update

1 month ago News 4 comments

Hey! Long time no see.

Okay, so it hasn't been that long, but definitely long enough that some stuff has happened! Beta is going pretty great. We've been Hammering out our bugs, making our props prettier, fixing our choreography and having some great recording sessions with our voice actors and actresses. Really, these guys are great, and they really bring the course experience together. We can't wait for you to hear them!

Amidst our polishing, general progress and whatnot, we've also gone ahead and set up a page over on Facebook. If you're interested in more frequent smaller updates (and you'd better be!), go ahead and follow us over there as well. It's a great time. We'll keep you guys posted, can get in touch with us, all that good stuff.


That's the brunt of our news for now. As a parting gift, have another peek at some of Beta's fruits. Remember this?

Well, JeffMOD and Crypt teamed up for Beta, and blew it out of the water.

That's all for now. We'll try not to be a stranger, and will have more updates for you soon. See ya then!

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.

So whats left to be done? Are you still adding to the map or maps, or are you just tweaking and adding bits and pieces to the maps? Or something else entirely?

Without going into specifics, and only covering the more major things; many areas still need further detail/lighting passes, some animations still need doing, our script is undergoing revisions, choreo hasn't been touched, and we've yet to contact our VAs for voice work.

Remember, we're still in Alpha, and this is only the notable, general stuff I could recall off the top of my head.
